Package Kit/Launch Server: avoid/ignore use of requires keyword

In C++20 `requires` is a reserved keyword. GCC13 warns against its use. This
change removes the use of the keyword in our own code, and ignores it in the
external 'libsolv' code.

Package Kit: Improvements to partial download handling.

* Move IsDownloadComplete call into DownloadFileRequest; this way
we will always revalidate checksums even if the file is fully
downloaded instead of skipping that.

* Treat ERANGE as a "bad data" error in PackageManager (it usually means
we have a size mismatch between the local and the server's file)

* If we fail checksum validation or get ERANGE, and we reused a download,
immediately try again without reusing the download. This fixes most
problems that previously required you to delete old transaction
directories.

Package Kit: re-use downloads from unfinished transactions

There are three parts to this change:
- In FetchFileJob, if the request fails with a timeout or IO error
(probably because of unstable connection) attempt to resume the
download with a range request. No limit on number of retries
currently, maybe we should add one.
- In PackageManager, before downloading a file, look around in other
transaction directories in case it's already there. Partial and
complete downloads are differentiated by an attribute which the
fetch file job maintains. For complete downloads, no fetch job is
scheduled, for partial downloads, the fetch job will request the
remainder of the file.
- In BHttpRequest, the implementation of SetRangeStart() and
SetRangeEnd() have been added, along with some refactoring to
handle listener notifications consistently. This also fixed a
bug where the final notification for download progress was not
emitted for compressed data.

Fixes #12414.

Package daemon notifications

* Sentence casing
* Localize notification texts in the package kit
* Have "Package daemon" as group name and "Warning" as title
* Use ::BPrivate in Bitmap.h to solve an ambiguity (as pointed out
by PulkoMandy). Though not needed for my changes any more, since
a the icon of the notifying app is now shown by default.

Fixes #13590.

SoftwareUpdater updates

Bug fix- show correct version on package uninstall list item tooltip
Correct if else formatting
Use the BPackageManager FullSync() function instead of Update
Change warning strings in BPackageManager to sentence casing
Show list item tooltip on a mouse down (helps with touch devices)

Package kit: more style fixes.

Pointed out by Axel this time. Thanks!

chroot support in package kit: style fixes

- Catching an exception in the normal flow is not a good thing, instead,
test before calling the function (I've been doing too much python
lately)
- Avoid using uninitialized nodeRef if there is no system root and also
no specified root in the message.

Thanks to Ingo or the code review.

Fix use of findpaths from inside chroot

The package kit needs to provide the package daemon with the node_ref of
the root directory, so the package daemon gives the correct results when
the request comes from inside a chroot.

Moreover, the package kit must be able to handle a root with a system
but no home package dir, as is the case inside the chroot environment
created by haikuporter.

Fixes #12602.

Moved BJob, and JobQueue into the support kit.

* Put it in the BSupportKit namespace, following the style introduced
with the package kit for now.
* The BSupportKit::BJob class no longer knows about the package kit's
Context class. However, the BPackageKit::BJob class does.
* Due to the namespace juggling, a lot of files had to be touched.
* The JobQueue class remains private.
* Due to the way Haiku is built on itself, you cannot build this change
under Haiku with an older release.

Package Kit: FetchFileJob now contains package size.

* So that you know how much already was, and still has to be downloaded.
* Automatic whitespace cleanup.
* The link in FetchFileJob.h did not fetch the correct header under
Haiku anymore (since the addition of the private headers to the
image).

BPackageManager: Add SetDebugLevel()

Sets the debug level of the solver.

Package Kit: Always allocate local repository

Consequently always register it with the solver in Init(). This solves the
problem that it made a difference at which time Init() is called. Init() is
called at the beginning of Install() and Uninstall(), but HaikuDepot was
calling it before that for other reasons. A second call to Init() will exit
early. If local package files were added to the PackageManager instance,
the local repository was created lazily, but because Init() did not run a
second time, the local repository was not registered with the solver. Now
it already is, since it is no longer created on demand, but always.

BPackageManager: Support installing/updating local package files

* The Install() and Update() versions that take a const char* array
now check whether a string looks like a path to a local package file.
If so, they use that file instead of interpreting the string as a
search string.
* Extend the repository hierarchy. There's now a LocalRepository base
class from which InstalledRepository and the new MiscLocalRepository
derive. The latter is instantiated once and collects all package files
specified by path.

BPackageManager: Make BCommitTransactionResult available

* BFatalErrorException: Add commitTransactionResult property and
respective constructor. In case committing the transaction failed,
BPackageManager throws a BFatalErrorException with the result.
* BFatalErrorException::UserInteractionHandler: Pass
BCommitTransactionResult to ProgressTransactionCommitted().

package daemon: Rework error and issue propagation to client

* BDaemonClient: Move inner class BCommitTransactionResult to top level
and make it public.
* BCommitTransactionResult:
- Add a whole bunch of specific error code enum values. Such an error
code is now the primary error, as opposed to before where we would
mix status_t and enum value errors. There's a systemError property
of type status_t which may provide additional information, though
(depending on the primary error type).
- Remove the errorMessage property. Due to mapping all errors to the
specific error codes this is no longer necessary. Mixing such a
message with another error description is also not very helpful when
it comes to localization (still not supported, though).
- Add several properties (paths, strings, error codes) that serve as
arguments to the primary error and are used by FullErrorMessage().
- Add issues property, a list of instances of new class
BTransactionIssue. Those describe non-critical issues (e.g. failed
update of a settings file) that occurred in the process of
committing the transaction. Those issues should be presented to the
user by the package management program.
* Exception: Adjust to transport the BCommitTransactionResult
properties.
* CommitTransactionHandler, FsTransactions, Root, Volume: Adjust to
BCommitTransactionResult/Exception changes.
* CommitTransactionHandler: Now requires a BCommitTransactionResult to
which it adds the issues it encounters. The reply BMessage is no
longer needed, though.
* Volume: Refactor common code from the three methods that use
CommitTransactionHandler into new method _CommitTransaction.

pkgman: Add full-sync command

* BSolver/LibsolvSolver: Add FullSync() method. It uses libsolv's
SOLVER_DISTUPGRADE mode.
* BPackageManager: Add FullSync() using the new solver mode.
* pkgman: Add full-sync command.

The new command is similar to the update command without arguments, just
more aggressive, allowing downgrading or even removal of packages, to
match the state of the repositories. Just like "update" it doesn't work
properly yet.

BPackageManager::UserInteractionHandler: Make non-abstract

Most of the hooks don't strictly need a non-empty implementation. The
defaults now simply throw exceptions in those that do. This allows the
class to be instantiated, which is useful when a BPackageManager is only
used for finding packages.

BPackageManager: Add mandatory constructor parameters

Require the installation interface and the user interaction handle to
be passed to the constructor. Formerly, derived classes set them
manually in their constructors. This makes using the class without
having to subclass it possible.

Remove /boot/common for good

* Remove support for the "common" installation location from packagefs,
package kit, package daemon, package managers.
* Rename the B_COMMON_*_DIRECTORY constants referring to writable
directories to B_SYSTEM_*_DIRECTORY.
* Remove/adjust the use of various B_COMMON_*_DIRECTORY constants.
I'm sure some occurrence still remain. They can be adjusted when the
remaining B_COMMON_*_DIRECTORY constants are removed.

Package Kit: Implement progress notifications.

- BJobStateListener: Add progress state and corresponding hook.
- FetchFileJob: Notify job progress hook on libcurl notifications.
- UserInteractionHandler: Add hooks for download progress and checksum
validation progress.
- PackageManager: inherit from JobStateListener and watch for job
notifications for internally generated jobs. Forward to corresponding
UserInteractionHandler hooks as needed.
- Adapt pkgman, HaikuDepot and package_daemon to above changes.
Neither HaikuDepot nor package_daemon's progress hooks are wired up to
do anything yet though.

BPackageManager: Eliminate RequestHandler.

- Pull functionality back into package manager itself since the extra
indirection doesn't really buy us anything in this case, as neither
request that it handles requires a decision provider.
- Adjust pkgman and HaikuDepot accordingly.

BPackageManager: Auto-refresh if repository cache is missing

This makes the initial "pkgman refresh" superfluous, that was necessary
for "install"/"search" to work.

BPackageManager::_CommitPackageChanges(): Fix error handling

The error returned by CommitTransaction() is just indicates whether
transactionResult has been initialized.

BPackageManager: Support pre-added packages

... as needed for the package daemon. _PreparePackageChanges() doesn't
try to clone them in this case.

BPackageManager: Add InstalledRepository::EnablePackage()

BPackageManager: Add ResultComputed() callback

BPackageManager: Add VerifyInstallation()

BPackageManager: Add alternate Install()/Uninstall()/Update()

BPackageManager: Make _InstallationRepository() protected

BPackageManager: Abstract installed repository initialization

* Rename TransactionHandler -> InstallationInterface and
DaemonClientTransactionHandler -> ClientInstallationInterface.
* Add InstallationInterface::InitInstalledRepository(). Use in
_AddInstalledRepository() to get the repository packages instead of
using the package roster. The ClientInstallationInterface
implementation does it that way.

Refactor reusable pkgman code into libpackage

* Move RepositoryBuilder class to libpackage and add B* prefix to name.
* Pull BPackageManager class out of PackageManager and move to
libpackage. The base class is customizable via three handler objects
responsible for transaction handling, request execution, respectively
user interaction.
* Reorganize _ApplyPackageChanges(): Now we first prepare the
transactions for all affected installation locations (downloading
files etc.) and then commit them.
