Copy:
* packages: Haiku -> HaikuBootstrap
* images: HaikuImage -> HaikuImageBootstrap
... and remove some unncessary content.
Setting the jam variable HAIKU_BOOTSTRAP_BUILD enables using the
bootstrap files.
* Deskbar now uses ~/config/settings/deskbar/menu_entries for its menu,
falling back to /system/data/deskbar/menu_entries, when the former
doesn't exist. The latter always exists and is a virtual directory
merging the deskbar/menu subdirectories of ~/config/settings/ and
<any installation location>/data/. So, if a package provides a
deskbar menu symlink, it is added automatically when the package is
activated. The user can add own menu items by putting stuff into
~/config/settings/deskbar/menu/, only use their own organization by
symlinking it to menu_entries, or do fun stuff by making menu_entries
a customized virtual directory.
* HaikuImage: No longer create any deskbar menu symlinks in the user's
settings directory. Instead add them to the Haiku package.
* OptionalPackages: At least for the optional packages that do have
hpkgs, no longer create deskbar menu symlinks in the user's settings
directory.
* Move all Deskbar settings files to ~/config/settings/deskbar/ and
drop the "Deskbar_" prefix.
* Also make use of new build feature rules.
* Since the hacky long_jump_buffer field has been removed from the
jpeg_error_mgr struct in the new package, the structure is now
wrapped in the JPEGTranslator code to achieve the same behavior.
We have to use actual targets that cause the respective download and
extract the packages. Otherwise the build fails when the packages
haven't been extracted yet.
* this package wraps the haiku_cross_devel package (i.e. it contains
that package in /develop/cross)
* the wrapper package is meant to be installed into the system
hierarchy, from where haikuporter will fetch the contained package
when needed
* Add new package haiku_loader.hpkg and move haiku_loader there. The
package is built without compression, so that the stage 1 boot loader
has a chance of loading it.
* Adjust the stage 1 boot loader to load the haiku_loader package and
relocate the boot loader code accordingly.
* build_haiku_image: Remove MIME DB creation code.
* Rename beos_mime source directory to mime_db.
* Add rules to build the MIME DB in the source directory's jamfile.
* Add MIME DB directory to haiku.hpkg in data/mime_db.
* Add optional packages Zlib and Zlib-devel.
* Simplify the build feature section for zlib and also extract the
source package.
* Replace all remaining references to the zlib instance in the tree and
remove it.
