480742bd7a KPath added to the build.

f3604f65e7 * Added missing `flags' parameter for the mount functions.
* fs_mount() and fs_unmount() are now aware of partitions. A device to
  be mounted is looked up by the DDM and the mount state and mount
  cookie of the corresponding KPartition are updated accordingly.
  Still missing is support for mounting files. Moreover the device path
  needs to be normalized.
* Added RecursiveLockAutoLocker class to ease the `goto errN' pain a bit.

5de8542789 Since the kernel links against libgcc.a and we use some C++ features that cause functions of libgcc.a to be included that use a couple of formerly undefined symbols (stderr, fprintf, abort, debugger) those had to be added to kernel_cpp.cpp. We don't build the kernel utils as static library anymore, since libgcc.a is listed at the end of the link command line and trying to change that would be a bit ugly. For C++ in the boot loader nothing changes.

1b5f626633 * Changes to use KPath where possible now.
* Made GetMediaStatus() a bit more robust. If the ioctl fails (e.g. if it
  is not implemented as in Thomas' drivers), it gets the device geometry
  and does not fail, if the device is not removable.

48ac51f886 Added support to map more than 4 MB in the kernel space. This became necessary
to be able to have more than 1280x1024x8 resolutions. The best solution, however,
would be to map the graphics memory outside of the kernel space, anyway.

a7fb02e6a2 No longer enables video mode when in debug mode (when a menu came up before
it switched to the logo mode afterwards).
Improved and broke the second call of platform_switch_to_logo() with a
different video mode: it now at least works when switching to a lower
resolution.

b81068c0c8 Turns out that the interrupts were temporarily turned on during startup,
and that main2() cannot therefore just wait until interrupts become
enabled.
Now, the main2() thread is resumed after interrupts are turned on.
I am not yet sure if this is really necessary, but I have the feeling that it is.

c9e4e71f10 Implemented optional additional serial output in the boot loader.
When the debug boot option is set, or ENABLE_SERIAL defined on compile time,
the serial port 1 is activated.
It will also read the serial base port info from the BIOS data and use
that if any ports are reported (will fall back to 0x3f8 if not).
Right now, a fixed baud rate of 115200 and 8n1 is used.

8083619cf7 Since the additional 512 bytes of dprintf() on the stack can potentially
change the flow of things, it now has its own buffer, and fills it with
interrupts disabled (everything comes at a price).
Now uses the safe vsnprintf() instead of vsprintf() which could crash
the kernel.

f9fea8ac78 A clean FPU state is now saved during init, and copied into every fresh
thread. That also allows kernel threads to use the FPU as well.
arch_thread_enter_uspace() no longer needs to initialize the FPU.
i386_stack_init() is now only called once, in arch_thread_init(), as
thought.

ad2a2999a9 In early boot mode, open_module_list() is not able to find everything we
want it to find; therefore, we're now using get_next_loaded_module_name().
Added a temporary suffix to the FS DDM modules (disk_device/v1) - they
might get merged with the standard FS interface modules.

93048e141e The decision to put reserved regions along real ones proves problematic: fixed
three code locations that didn't handle them properly (when iterating over all
areas).
That and the fact that unmap_and_free_physical_pages() is no longer broken now
leads to the boot region being unmapped and freed properly as intended before.
That revealed another bug: the boot loader region was disposed too early, we
need a few other components pick up boot loader resources first; it now happens
in vm_init_post_sem().
allocate_kernel_args() was also broken, and actually didn't try to allocate
kernel args areas, but tried to reallocate all the virtual allocated ranges
of the boot loader...

64807a40c3 As Thomas and I found out in a late debugging session, the VM handled the
boot loaders passed in memory completely wrong (for example, the premapped
graphics buffer could be mapped to the same region as some thread stacks,
just because the VM did not use its knowledge about that mapping): the boot
loader regions are now reserved so that they cannot be overwritten
with other regions anymore. The kernel_args arguments are now tracked, and
areas are created for them (they are not yet freed, though). arch_vm_init_end()
must now call the new vm_free_unused_boot_loader_range() to free any remaining
parts of the memory not yet mapped in by any areas.
Renamed a lot of init functions (ie. postsem to post_sem, init2 to post_area),
also updated because of the vm_translation_map*() arch_vm_translation_map*() move.
B_ALREADY_WIRED can now only be used during kernel startup (it's a private flag).
Replaced PAGE_SIZE with B_PAGE_SIZE.
Some minor cleanups.

Renamed the internal vm_translation_map_quick_query() to early_query(),
renamed vm_translation_map_quick_map() to arch_vm_translation_map_early_map().
Removed the _module part of the initialization functions.
Added a function that completes the initialization of the kernel map (it
creates the map's lock, which was just not done before).
arch_vm_translation_map_init_map() will now fail with an appropriate
error code if the map's lock couldn't be created for anything that
is not the kernel map.

Changed return types to status_t rather than just having "int" stand
for a status code.

11f838fbf7 Updated due to changes to the kernel_args frame buffer structure.
Most importantly, it now always uses map_physical_memory(), and no longer
relies on eventually mapped data by the boot loader (that the VM didn't
know about).

09ff55a821 BeGeistert checkin: we now have memalign() - and because of that, the
USE_WALL feature can now be used.
Started implementing a USE_CHECKING_WALLS feature, that has a kernel
daemon running that periodically checks the walls of *all* memory
allocations - does not work yet (because of some initialization order
problems).

8593dcc214 Being on a kernel stack doesn't mean we didn't come from userland: we now
no longer pop %fs from the iframe in that case, too.
When we restore a custom stack, however, we'll now pop %fs from the iframe
as such strange threads may even do their own business with it.
Added some comments.

bd4b903e57 Switched from the old team_create_team() to a load_image() compatible mechanism.
The path name is now always taken from the provided argument list (except for
_user_exec() which now replaces args[0] with the path argument).
The team_arg structure know nows if it must delete its arguments or not - this
also fixes a memory leak in case team_create_team() failed when invoked from
userland.
load_image() is now also exported for the kernel.

4711148ca9 wait_for_child() can now also wait on children in the current or any other
process ID (in the current session).
get_death_entry() could call free() with interrupts disabled; now follows
the same mechanism as chosen with the groups (ie. it returns a pointer
to a death_entry to be freed by the calling function).

6a70123a9d Big update, but everything is related:
- we now have a working process group/session model. Implemented related syscalls
  and the kernel backend, some POSIX process functions are now available in the
  kernel as well.
- dying teams now monitor their exitus by leaving death_entry structures in
  their parent team.
- Implemented wait_for_child() for pid == -1 and pid > 0; IOW waiting for process
  groups is missing yet. Hasn't yet been tested intensively.

48e64cd7c8 Added two experimental release_sem_etc() flags (both should stay, but they
may be renamed):
- B_RELEASE_ALL: the semaphore count is set to 0, all waiting threads are released
  (the "count" argument of release_etc_sem() is ignored then)
- B_RELEASE_IF_WAITING_ONLY: the semaphore count is only decreased if there
  are any waiting threads; ie. the semaphore is signaled
Together, they will make the pthread_cond_*() functions easy to implement, and
they come in handy at other places, too.
Removed release_threads variable in release_sem_etc(), as it was useless.

c2289a8876 Changed the way a dying thread propagates its exit status and reason: we
