61b37794a4 Added explicit support for loading executables compiled with the
respectively other gcc version on a Haiku compiled with gcc 2 or gcc 4.
The libraries for such an executable are first searched in "gcc4"
respectively "gcc2" subdirectories of the standard search path
directories. If not found there, we try again with the standard paths.

8560d1885b * The runtime_loader's test_executable() no longer analyzes the
executable permissions of the file by hand. We use _kern_access()
  instead, which also handles the root case correctly.
* The user and group arguments of test_executable() aren't needed any
  longer.

12a5e9a4a2 bonefish+axeld:
The runtime loader did not correctly resolve %A correctly with the
actual normalized program path. IOW it would not work correctly with
symlinks to applications that had their own lib directory.

1873b4b37e Give the runtime loader a chance to reinit its semaphore after fork().

74c0424a43 * 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.

46f4d84912 * Got rid of sLoadingImages. It was always empty.
* The previous symbol resolution code was incorrect. It would search all
  loaded images in the order they had been loaded. Thus an add-on would
  possibly see a symbol of an earlier loaded add-on. Now we search
  recursively starting with the respective root image (executable or
  add-on).
* Added BeOS style symbol resolution and made it the default. A symbol
  undefined in an image is only searched in its direct dependencies.
  Fixes bug #889 (BeOS apps crashing under Haiku when opening a file
  panel).

6f0994d460 * 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).

7f4e6824df Added a private call to get the dependencies of a loaded image. This will be used
to determine linkage of libnet.so vs. libsocket.so/libbind.so in the libnetwork.so.

0cd3c003d1 While investigating how our deals with doubled shared libs, I found two
issues:
* Our glue code was broken after all - it allowed Haiku apps to start under
  BeOS (and vice versa), but the initialization/termination functions were
  called with an invalid image ID - on *both* sides! As it turns out, the
  Be glue code did *something* with %ebx, but certainly didn't put the image
  ID in there, but just passed it on the stack, as we did before (just in
  the wrong order...). Therefore, the arch_call_init_term stuff is not
  necessary.
* When unloading add-ons, their termination functions were never called, as
  the image (for get_image_symbol()) was already made inaccessible, and
  therefore the symbol couldn't be found.

9a6bbd514e Once libroot's getenv() is available, that one will be used instead of the one built in.
This makes the runtime_loader able to adopt path changes properly.
