Ingo Weinhold 6075e354ab * Call module_init_post_boot_device() right after the boot volume has
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.

Axel Dörfler 5a123e3591 * Added a post boot device module init function that unloads all unused modules,
as they aren't unloaded when there is no boot device yet.

Axel Dörfler 423fcd43ae * Shuffled initializers around: the team, ELF, and module initializers come
now a lot earlier.
* That makes it now possible to use modules pretty early in the kernel (like
  before timer_init(), or int_init_post_vm()).

Axel Dörfler 0875ae984f * Preparations for a module listener API - this will be used in the (disk)
device managers.
* Cleanup.

Axel Dörfler ceba105306 Added function prototypes for the kernel private load_module() and unload_module() calls.
Made the header C++ safe.

Axel Dörfler 564cba312e Some header work: removed unnecessary dependencies to stage2.h, fixed
some broken C++ export definitions, added missing licenses etc.

Axel Dörfler 4e3c12c0af Moved <types.h> to <sys/types.h>.
Removed dependencies on arch/x86/types.h - this file is not really used
anymore, now. Might prevent compiling on Windows, though.
Replaced "int" with "int32" for the id types.
Removed some stuff from ktypes.h because it didn't belong there.
