Support x86_64 in the runtime loader.

* Added x86_64 linker script and relocation code.
* Some 64-bit safety fixes to the heap code.
* Added runtime_loader, libroot and bash to the x86_64 image. The boot
script will be launched, but will panic shortly after because fork
is broken.

Revert hrev43458.

This reverts commit 80e6a84bf008b3479413d37737f1889bd2a02905.

Fix alignment mask, sorry for the noise.

Add a simplistic memalign() to the runtime_loader heap.

As KMessage now makes use of memalign() the simple heap in the
runtime_loader needs to provide that as well. Fixes build.

Implemented realloc().

* Added a mechanism to retrieve a BMessage with eventual error descriptions
for _kern_load_image().
* Added KMessage to the runtime_loader (a bit hacky, though) - it will use
it to deliver the above mentioned functionality.
* load_dependencies() did return the wrong status code in case a library
was missing; now it returns B_MISSING_LIBRARY.
* load_dependencies() will now try to load all dependencies when a report
message is requested; therefore, all missing libraries are listed.
* Renamed uspace_program_args to user_space_program_args.
* The kernel filled in various members of the user_space_program_args structure
unsafely, ie. was not using user_memcpy().
* Renamed some local variables in team.c to better fit our style guide (ie.
uargs to userArgs).
* Changed Tracker to use the new _kern_load_image() variant on Haiku to retrieve
and report all missing libraries. This fixes bug #1324.
* Adapted kernel_cpp.cpp to the runtime loader as well; the latter will now
compile with _LOADER_MODE defined.

The heap now grows if needed; this allows VLC to load all of its plugins.

* Switched to the boot loader's heap implementation.
* This sane heap revealed a bunch of bugs (like sLoadedImageCount not being
maintained that was used for various allocations).
* If the allocation of the image fails, opening the app will now just fail
instead of crashing of overwriting random data (IOW VLC will now load
okay, but cannot load some of its add-ons anymore).
