2965c99fea * Changed the _kern_exec() and _kern_load_image() syscalls. They expect
a flattened argument/environment buffer now. This simplifies the work
  for the kernel a bit, since it can just copy the buffer and check
  whether it looks OK instead of messing around with individual strings.
  The runtime loader also gets a flattened array.
* Set the maximum size of the arguments/environment buffer to 128 KB.
  When more arguments are passed, we fail with a proper error code
  (instead of just truncating the arguments as before).
* On exec*() the first argument was silently replaced by the given path
  name, which is not correct.

f5b3a6a796 * Initialize all static mutexes in the kernel through a MUTEX_INITIALIZER()
and remove the then unneeded mutex_init() for them.
* Remove the workaround for allowing uninitialized mutexes on kernel startup.
  As they are all initialized statically through the MUTEX_INITIALIZER() now
  this is not needed anymore.
* An uninitialized mutex will now cause a panic when used to find possibly
  remaining cases.
* Remove now unnecessary driver_settings_init_post_sem() function.

6b202f4e3d * Introduced new header directory headers/private/system which is supposed
to contain headers shared by kernel and userland (mainly libroot).
* Moved quite a few private kernel headers to the new location. Split
  several kernel headers into a shared part and one that is still kernel
  private. Adjusted all affected Jamfiles and source in the standard x86
  build accordingly. The build for other architectures and for test code
  may be broken.
* Quite a bit of userland code still includes private kernel headers.
  Mostly those are <util/*> headers. The ones that aren't strictly
  kernel-only should be moved to some other place (maybe
  headers/private/shared/util).

4c49f2056b * Changed _kern_spawn_thread() and create_thread(): Instead of individual
arguments they get a single thread_creation_attributes structure now.
* Added stack_address and stack_size to thread_creation_attributes,
  which allow to specify the stack size or the stack to be used for the
  new user thread.

0c615a01ae * Removed old mutex implementation and renamed cutex to mutex.
* Trivial adjustments of code using mutexes. Mostly removing the
  mutex_init() return value check.
* Added mutex_lock_threads_locked(), which is called with the threads
  spinlock being held. The spinlock is released while waiting, of
  course. This function is useful in cases where the existence of the
  mutex object is ensured by holding the threads spinlock.
* Changed the two instances in the VFS code where an IO context of
  another team needs to be locked to use mutex_lock_threads_locked().
  Before it required a semaphore-based mutex implementation.

7727e08e5f Added experimental public API get_port_message_info_etc(). It is similar
to port_buffer_size_etc(), but returns the info through a structure,
which also identifies the sender (uid, gid, team ID) of the message.

  longer.

392ad2822d axeld + bonefish:
BeOS R5's glue code incorrectly calls _thread_do_exit_notification()
when main() returns, while Haiku does that in exit(). Therefore when
terminating this way the exit hooks were called twice for executables
built under BeOS R5. This caused e.g. NetPositive or the R5 svn to
crash on exit (our network code actually uses those hooks).
Fixes bug #1742.

34b3b26b3b Merged branch haiku/branches/developer/bonefish/optimization revision
23139 into trunk, with roughly the following changes (for details svn
log the branch):
* The int 99 syscall handler is now fully in assembly.
* Added a sysenter/sysexit handler and use it on Pentiums that support
  it (via commpage).
* Got rid of i386_handle_trap(). A bit of functionality was moved into
  the assembly handler which now uses a jump table to call C functions
  handling the respective interrupt.
* Some optimizations to get user debugger support code out of the
  interrupt handling path.
* Introduced a thread::flags fields which allows to skip handling of
  rare events (signals, user debug enabling/disabling) on the
  common interrupt handling path.
* Got rid of the explicit iframe stack. The iframes can still be
  retrieved by iterating through the stack frames.
* Made the commpage an architecture independent feature. It's used for
  the real time data stuff (instead of creating a separate area).
* The x86 CPU modules can now provide processor optimized versions for
  common functions (currently memcpy() only). They are used in the
  kernel and are provided to the userland via commpage entries.
* Introduced build system feature allowing easy use of C structure
  member offsets in assembly code.

Changes after merging:
* Fixed merge conflict in src/system/kernel/arch/x86/arch_debug.cpp
  (caused by refactoring and introduction of "call" debugger command).

fcfbb8aa6c libprefs.so uses the private _klock_node_() syscall, and even loops until it
returns success - since this stub always returned failure, this prevented all
apps using that library (like Gobe Productive) from running.
It now calls the Haiku equivalent _kern_lock_node(), and Gobe now runs fine!
This closes bug #562.

636bfc08ae * Renamed fs/vfs_select.cpp to wait_for_objects.cpp and got rid of
vfs_select.h, respectively moved most of it into the new kernel
  private header wait_for_objects.h.
* Added new experimental API functions wait_for_objects[_etc](). They
  work pretty much like poll(), but also for semaphores, ports, and
  threads.
* Removed the "ref" parameter from notify_select_events() and the
  select_sync_pool functions as well as from fd_ops::fd_[de]select(). It
  is no longer needed. The FS interface select() hook still has it,
  though -- the VFS will always pass 0.
* de]select_fd() take a select_info* instead of a select_sync* + ref
  pair, now. Added respective functions for semaphores, ports, and
  threads.

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.

44b5d72b5a Added new functions to the debugger API:
{set,clear}_debugger_{break,watch}point(), allowing to set/clear break
and watchpoints for the calling team. When a break/watchpoint is hit,
the team enters the debugger. Handy in situations when the program in
question can't really be started in a debugger (or it would be
complicated to do so). The functions work only as long as no debugger is
installed for the team.

We clear the arch specific team and thread debug infos now, when a new
debugger is installed, thus clearing break- and watchpoints.

1cbf8f4b3c initial support for a commpage, which is a chunk of memory in high kernel space with user readonly permissions.
The first use is to let the kernel decide what the preferred syscall mechanism is at boot time and copy the
appropriate user space code there. Can be used for routines the kernel can decide best how to use (memcpy, some
timing routines, etc).

ea4ff0f689 is_computer_on() lives again as a true syscall.
Replaced the _kern_null syscall with _kern_is_computer_on.
is_computer_on_fire is a bit harder, since it returns a float from kernelland, which
at the moment isn't supported in haiku.
