Add install path support to packagefs

Add architecture property to Package

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).

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.

Rename Package "name" property to "fileName"

* 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.

* Package: Added Open() (and matching Close()) method, which opens the package
file once, tracking an open count.
* Added VFSInit()/VFSUninit() methods to the Node and PackageNode class
hierarchies, called by the {get,put}_vnode() PackageFile implements them to
set up/tear down access to the file data. Also added a Read() reading the
data.
* Implemented the open(), free_cookie(), and read() FS hooks for real. Reading
files works now. Executing doesn't yet -- it requires working with
IORequests in a way not supported by the userlandfs.

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.
