Build a separate libsupc++ for the kernel with correct flags.

Kernel mode code on x86_64 needs to be built with -mno-red-zone as
interrupts would corrupt the red zone if it were in use. However, the
kernel is linked with libsupc++, which was not compiled with
-mno-red-zone. If an interrupt occurred in libsupc++ code the red zone
would get corrupted. This was causing random panics, particularly under
heavy system load. Therefore, on x86_64 a separate build of libsupc++
with -mno-red-zone is now done for the kernel to use. Note: this commit
will require a rerun of configure and rebuild of cross tools.

Attribute index support for non-special attributes

* Add AttributeIndex class.
* Each attribute does now have an attribute index cookie. The new
attribute index service methods Node::IndexAttribute() and
IndexCookieForAttribute() create+set/retrieve the cookie. The cookie
is actually the attribute index's tree node.
* Add OldNodeAttribute::IndexCookieForAttribute() so the cookie is
available when the node changes.

Move helper function out of QueryParser.h

They live in the new QueryParserUtils.{h,cpp} now.

Add last modified index support

* Add class LastModifiedIndex.
* Create and add an instance of it in Volume::Mount().

Add size index support

* Add class SizeIndex.
* Create and add an instance of it in Volume mount.

NodeListener::NodeChanged(): Provide old value

* Add interface OldNodeAttributes an instance of which is passed to
NodeListener::NodeChanged() to provide the old attribute values
(currently only modification time and file size).
* Also extend PackageLinksListener::PackageLinkNodeChanged() with a
OldNodeAttributes parameter.
* Add OldNodeAttributes implementations for PackageLinkSymlink (inner
class OldAttributes) and UnpackingNode (OldUnpackageNodeAttributes).

Add Query class and query management in Volume

Add NameIndex class and create instance in Volume

Add Index base class and index table in Volume

Add a global node listener mechanism

Support for auto-generated package node attributes

* Add utility class AutoPackageAttributes and AttributeCookie subclass
AutoPackageAttributeCookie.
* UnpackingAttributeCookie::Open() does now try to create a
AutoPackageAttributeCookie, when it doesn't find the attribute in the
PackageNode.
* Adjust UnpackingAttributeDirectoryCookie to also list auto-generated
attributes.

Currently the only supported attribute is "SYS:PACKAGE", which is the
file name of the package containing the node.

Move PackageLinkDirectory::Link to own file

And rename it to PackageLinkSymlink.

WIP towards dependency package links

* Add ResolvableFamily and DependencyFamily classes for grouping equally
named resolvables/dependencies.
* Add hash tables to PackageFSRoot to track resolvables and
dependencies. That is done in {Add,Remove}Package.
* Resolvable does now have a list of Dependency objects, the ones it
satisfies.

Add package link directories to system volume

* Add PackageLinksListener interface. It is used by
PackageLink[s]Directory to notify a listener about changes.
* Volume does now implement PackageLinksListener and recursively adds/
removes package link directories.

This makes the package link directories appear at least. They are still
empty.

WIP: Create empty package links directories

* Rename PackageFamily to PackageLinkDirectory and derive from
Directory.
* PackageLinksDirectory: Add the PackageLinkDirectory objects as
children and remove the no longer needed hash table (we use the
Directory's child hash table).

Move EmptyAttributeDirectoryCookie to own files

Add yet empty package-links directory

* Add PackageLinksDirectory Directory subclass. Currently not doing
anything.
* PackageFSRoot: Create a PackageLinksDirectory.
* Volume: Add/remove the package links directory for the system volume.

Pull derived UnpackingDirectory out of Directory

Move all package specifics from now abstract Directory to new derived
class UnpackingDirectory and adjust the Volume implementation
accordingly. This concludes the Node/Directory refactoring. Neither
class is aware of packages anymore.

Rename LeafNode to UnpackingLeafNode

Remove package related dependencies from Node

* Move package related methods from Node to new interface UnpackingNode.
* LeafNode and Directory derive from UnpackingNode now.
* Adjust Volume implementation accordingly.

Attribute dir access kernel interface abstraction

* Introduce interface AttributeDirectoryCookie and currently only
implementation UnpackingAttributeDirectoryCookie. This is an interface
for reading/rewinding an attribute directory.
* Add abstract virtual Node::OpenAttributeDirectory() method that
returns an AttributeDirectoryCookie and implement it for derived
classes.
* In the kernel interface attribute directory hooks use
AttributeDirectoryCookie now.

Kernel interface abstraction for attribute access

* Introduce interface AttributeCookie and currently only implementation
UnpackingAttributeCookie. This is an interface for reading/stat()ing
an attribute.
* Add abstract virtual Node::OpenAttribute() method that returns an
AttributeCookie and implemented it for derived classes.
* In the kernel interface attribute hooks use AttributeCookie now. The
attribute directory hooks are unchanged.

WIP towards packagefs package links support

* Introduce Version class representing a version.
* Introduce Dependency and Resolvable class and add lists of either to
Package.
* Parse package attributes and add dependencies and resolvables to
Package.
* Add a mount type to Volume and add a respective mount parameter
"mount-type" (values "system", "common", "home", "custom"). Also
implies the shine-through type, if that's not given.
* Introduce class PackageFamily which groups equally named and versioned
packages.
* Add class PackageFSRoot. Each instance represents a possible file
system root (separate roots for different chroot environments). Tracks
Volumes belonging to the same root and their packages.

Split package kit DataReader.cpp

Pull AttributeDataReader and FDDataReader implementations out of
DataReader.cpp into own source files. Thus we can avoid dependencies
(e.g. to fs_attr code) we don't need/want.

Pulled reusable stuff from PackageReaderImpl into new class ReaderImplBase.

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
* adjusted 'package'-binary and packagefs accordingly


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40320 a95241bf-73f2-0310-859d-f6bbb57e9c96

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


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40301 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Extract the attributes from the package files and attach them as
PackageNodeAttribute to the PackageNodes.
* Implemented the attribute FS interface hooks.
* Made Package and PackageNode BReferenceable.
* Fixed the reference management for Node.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34119 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added new interface BufferCache -- basically a memory allocator with the
option to cache a freed buffer -- and implementations
BlockBufferCache{NoLock,Kernel}.
* ZlibPackageDataReader does now dynamically get its read and uncompress
buffers from a provided BufferCache when needed.
* Allocating the buffers once and keeping them over the whole life time was a
bit too memory heavy, since we create a reader for every file for which a
vnode is created. A FS module global factory provides a buffer cache.
* Added a mutex to PackageFile::DataAccessor which guards the access to the
data reader which isn't thread safe.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34115 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented intermediate base class PackageLeafNode for PackageFile and
PackageSymlink with a "fat" interface.
* Replaced File and Symlink by fat class LeafNode.
* Added Package* object management to Directory and LeafNode.
* Implemented packagefs_read_symlink(), so symlinks work now.
* Added some missing locking the kernel interface.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34096 a95241bf-73f2-0310-859d-f6bbb57e9c96

Work in progress:
* The FS parses package files from "/boot/common/packages" and builds an
node tree representation of the contained entries. Merging directories should
work. Lots of other stuff is missing yet, though.
* Implemented the hooks for directory entry lookup and iteration. So it's
possible to see the contents of the FS at least.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34088 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented the most basic functionality required to cleanly mount and unmount
(at least in userlandfs).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34069 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added Jamfile for building for the userlandfs.
