* No longer send a SIGKILL when a page fault occurred, there was no
signal handler, and the debugger told us to continue as usual. Instead
we send a SIGSEGV. Instead in handle_signal() when not in the main
thread and there's no handler for the signal, we first send the main
thread a SIGKILL before letting the thread die.
So in cases where the main thread caused an unhandled page fault, the
team will die from the SIGSEGV, now. This fixes bug #2773.
* For the other hardware-caused signals we do now do the same as in case
of page faults, i.e. we first check whether the thread has a handler
for the signal in question. If so, we don't notify the debugger, but
send the signal right away.
* B_GENERAL_PROTECTION_FAULT is translated to SIGILL now. Seems better
than SIGKILL.

letting the boot loader provide full paths for the pre-loaded images.

been mounted, before anyone could try to load any modules from it.
Also pass it a flag whether the boot volume is where the boot loader
pre-loaded the modules from.
* module_init_post_boot_device() changes the pre-loaded module image
paths to normalized boot volume paths, now. Got rid of the code in
register_preloaded_module_image() which tried something like this.
* Changed module image ref counting. A referenced module has single
reference to its image, which is released when the module becomes
unreferenced.
* get_module() for a reference module will not try to re-get and re-set
the module's image anymore. That could lead to a similar module (from
different paths) being loaded at the same time. A module from a new
file can only be loaded when the old one has been put completely.
* Simplified B_KEEP_ALIVE module handling a bit. When the module is
initialized, we add another reference, which we'll never free. Thus
the module remains loaded without special handling. Removed
module_image::keep_loaded. A B_KEEP_ALIVE module remains referenced
and thus its image remains referenced, too.
* Removed module::file, a cached path to the module's image. An
optimization that wouldn't work with multiple root directories for
modules (/boot/beos/..., /boot/common/...) or when module files were
moved. get_module() does now always search the image file, when the
module is still unreferenced. This should be a bit slower than before,
but I didn't notice any difference in VMware at least. If it turns out
to be a problem we could introduce a more intelligent cache that stays
up to date by using node monitoring.

function (normalize_path()), now. There was some code duplication
before.
* Added "bool traverseLink" parameter to vfs_normalize_path(). When
true and the leaf component is a symlink, it will be resolved.
* KPath:
- Added similar leaf link traversal parameter to SetTo() and
SetPath().
- Added Normalize().
- Added DetachBuffer(), which returns the object's current buffer and
unsets itself.

elf_add_memory_image_symbol(). The former creates and registers a new
image that has not been loaded from a file. The latter adds a symbol to
its symbol table. This is mainly a debug feature, allowing to name code
or data in memory regions that aren't associated with loaded ELF
objects.

ELF symbols do now have a correct size.

translate addresses in the runtime loader correctly.
Note that this change will break code that assumes that the application
image is the first image returned by get_next_image_info().
