* Introduce on-container jam variable HAIKU_CONTAINER_SYSTEM_DIR_TOKENS
containing the directory tokens relative to the container root to
refer to system.
* Use the variable in *ToContainer rules that need to put something in
system.
* AddFilesToContainer: Fix overlooked reference to AddFilesToHaikuImage.
* AddBootModuleSymlinksToContainer: Use relative symlinks. This avoids
special-casing in the boot loader for packagefs.
The HaikuPackage rule now sets the variable
HAIKU_CURRENTLY_BUILT_HAIKU_PACKAGE to the given package and all
*ToPackage rules use that instead of a parameter. This saves passing the
package in each of those rule invocations.
Move common code from AddDirectoryToHaikuImage/AddDirectoryToPackage to
AddDirectoryToContainer. AddDirectoryToPackage was incorrect, using an
incorrect search directory for the attribute files.
* Create rules (build/jam/PackageRules) and a script,
build_haiku_package, to build hpkg files.
* Move all rule invocations that copy files and created symlinks and
directories in the "system" directory from HaikuImage to
HaikuPackages, which creates a package "haiku.hpkg".
* build_haiku_image: Comment out adding the copyrights info to
AboutSystem for the moment.
