package command: -z now takes an argument to specify the compression method.

The upcoming change to use zstd by default will make the -z no-argument
variant obsolete, so instead we need to support passing "zstd" or "zlib"
to actually indicate the compression method we want to use.

package: prevent creating a package that contains itself.

Fixes #10117.

package: Explicitly use B_HPKG_COMPRESSION_NONE

Allow specifying the compression level for package creation

* Introduce BPackageWriterParameters which comprises all parameters
for package creation, currently flags and compression level. Such an
object can be passed to BPackageWriter::Init() and is passed on to
PackageWriterImpl and WriterImplBase.
* PackageFileHeapWriter: Add compressionLevel property and pass the
value on to ZlibCompressor.
* package add/create: Add options -0 ... -9 to specify the compression
level to be used.

package kit: some fixes for multi-version support

* Use enums/constants/functions instead of preprocessor macros.
* Missing include in PackageInfoAttributeValue.h.
* PackageReaderImpl::Init(): Check version before header size and
return B_MISMATCHED_VALUES instead of B_BAD_DATA, if the version
doesn't match. This allows callers to determine the condition and
try a reader for a different version. A more flexible interface for
that case would be nice, but since we want to support the old package
version only temporarily, the current solution should be good enough.

package_repo: Removes dependency to package

* Move StandardErrorOutput to libpackage and into proper namespace to
avoid "package_repo" having to reuse the "package" source file.
* package_repo: Fix incorrect includes of "package.h".

Add options -b and -I to package command

* With -b building a build package can be requested. It will be empty
save for the .PackageInfo. No license check is performed.
* -I allows to specify an install path.

Move directory iteration helper to own file

Move PackageWriterListener to separate file

Missing include

Add create -i option for specifying a package info

Fixed printf() format related warnings.

Largish adjustments to PackagerReaderImpl and package attribute
handling:
* package attributes are now compatible with the low level attribute
handling of other HPKG attributes (such that 'package dump' now shows
package attributes, too)
* dropped type names from hpkg format, the attributes were identified
by IDs already and this simplifies the code considerably. Type names
are now handled in BLowLevelPackageHandler only.
* instead of rolling their own mechanism, high-level package attributes
handling is now implemented via a corresonding set of
AttributeHandler-subclasses
* adjusted package writer to only write package attributes that are
needed (empty ones are left out)

Implemented repository writing:
* fleshed out RepositoryWriterImpl
* renamed BRepositoryHeader to BRepositoryInfo (in accordance with
BPackageInfo)
* adjusted BRepositoryInfo to be able to parse itself from a
driver_settings file
* added package_repo binary (only 'create' works as of yet)

* implemented checking of licenses, such that it is no longer possible
to create a package that refers to a license that is not a system
license or contained in the package
* added package-info flags (currently only approve_license and
system_package)
* adjusted package-reader/writer and pkgman accordingly

Refactoring step towards implementation of RepositoryWriter:
* pulled commonly useful parts out of PackageWriterImpl into
WriterImplBase
* moved CachedStringTable and related methods into a separate class,
StringCache, in order to support having more than one string cache
per package file
* made package attribute section use a string cache, too, as that's
going to be very useful for repositories
* instead of writing package attributes directly, we now collect
corresponding PackageAttributes and write those later
* adjusted package reader accordingly

Refactored hpkg implementation to provide some separation between
public and private API (still far from ideal, but a start):
* moved several HPKG-classes into the public namespace BPackageKit::HPKG
* added fImpl-wrappers around PackageReader and PackageWriter to hide
most of the gory details

More work on package kit:
* added class BPackageInfo, which contains packaging attributes of
a package (the values relevant for package management)
* implemented parser (mostly) for reading a BPackageInfo from a config
file (.PackageInfo) in order to pass them on to the PackageWriter
when creating a package
* pulled hpkg-related stuff from bin/package into the package kit
* adjusted packagefs-Volume to skip .PackageInfo files when populating
the mountpoint, as those files shouldn't appear as part of an
activated package

format itself.
