options.
* module_init() now sets sDisableUserAddOns to whatever the safemode settings
say, ie. the B_SAFEMODE_DISABLE_USER_ADD_ONS setting is now respected by
the module code.
* Minor cleanup.

than you own - instead of crashing some time later, it will now panic as
soon as it can.
* No longer put the module image for B_KEEP_LOADED modules - essentially,
that feature was broken.
* Now use the RecursiveLocker in favour of manual locking where appropriate.
This actually fixed two locking bugs in error code paths.
* Applied a patch by François Revol: open_module_list() did not work
when the prefix was already inside a module (as opposed to a directory
on disk). The current solution is not as efficient, but that can be
fixed by improving the iterator code.

* Images preloaded by the boot loader had to be modules to be of any use
to the kernel. Extended the mechanism so that any images not accepted
by the module code would later be tried to be added as drivers by the
devfs. This is a little hacky ATM, since the devfs manages the drivers
using a hash map keyed by the drivers inode ID, which those drivers
obviously don't have.
* The devfs emulates read_pages() using read(), if the device driver
doesn't implement the former (all old-style drivers), thus making it
possible to BFS, which uses the file cache which in turn requires
read_pages(), on the device. write_pages() emulation is still missing.
* Replaced the kernel_args::boot_disk structure by a KMessage, which can
more flexibly be extended and deals more gracefully with
arbitrarily-size data. The disk_identifier structure still exists,
though. It is added as message field in cases where needed (non net
boot). Moved the boot_drive_number field of the bios_ia32 platform
specific args into the message.
* Made the stage 1 PXE boot loader superfluous. Moved the relevant
initialization code into the stage 2 loader, which can now be loaded
directly via PXE.
* The PXE boot loader does now download a boot tgz archive via TFTP. It
does no longer use the RemoteDisk protocol (it could actually be
removed from the boot loader). It also parses the DHCP options in the
DHCPACK packet provided by PXE and extracts the root path to be
mounted by the kernel.
* Reorganized the boot volume search in the kernel (vfs_boot.cpp) and
added support for network boot. In this case the net stack is
initialized and the network interface the boot loader used is brought
up and configured. Since NBD and RemoteDisk are our only options for
net boot (and those aren't really configurable dynamically) ATM, the
the boot device is found automatically by the disk device manager.
Booting via PXE does work to some degree now. The most grievous problem
is that loading certain drivers or kernel modules (or related activity)
causes a reboot (likely a triple fault, though one wonders where our
double fault handler is on vacation). Namely the keyboard and mouse input
server add-ons need to be deactivated as well as the media server.
A smaller problem is the net server, which apparently tries to
(re-)configure the network interface we're using to boot, which
obviously doesn't work out that well. So, if all this stuff is disabled
Haiku does fully boot, when using the RemoteDisk protocol (not being
able to use keyboard or mouse doesn't make this a particular fascinating
experience, though ;-)). I had no luck with NBD -- it seemed to have
protocol problems with the servers I tried.

When iterating through modules, the iterator was loading the module file, inserting it into the module image hash. Then, the first time get_module() was called on a module contained in the image, it was trying to load the image again. It probably actually was. Changed the logic to call get_module_image() which checks to see if it's already loaded.

used during early boot. Thanks!
* Fixed open_module_list() so that it can deal with a NULL prefix.
* Added a note that get_next_loaded_module_name() is implemented incorrectly.
* Minor cleanup.

no on-disk modules could be found... (since revision 16584).
* iterator_get_next_module() now makes use of the KPath features, and doesn't
build the new path manually anymore.

longer pushing a whole path on the stack.
* open_module_list() now adds the prefix to the paths it puts on the
stack to reduce the amount of searching to do (this probably wasn't
done before because of the earlier boot method via bootfs which
didn't allow for deep path names).
* module.c is now module.cpp (for KPath usage).
