e2a938c274 Add define for the kernel area to ppc & m68k. They still don't initialize TLS though.

Gerald Zajac. Thanks a lot!
* Also put it on the image by default.

b3d6c12dbf * Fixed kernel tracing for gcc 4. The ABI changed in a way that isn't
compatible with what our code assumed (pointers to objects of
  TraceEntry and its POD base class trace_entry aren't identical
  anymore).
* Added optional stack traces for ktrace_printf() output in the kernel.

fbe0c27a94 axeld + bonefish:
Changed condition variables so that it is allowed to block (e.g. lock
mutexes etc.) between Add() and Wait(). This fixes #2059, since the
block writer used them this way and could thusly fail to wait for a
condition variable, causing a temporary stack object to be used past its
lifetime.

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).

d648afb8d7 * For each userland team the kernel creates an area in the userland
address space that is fully locked and marked B_KERNEL_AREA. It can
  thus be accessed by the kernel without additional checks.
* For each userland thread we do create a user_thread structure in that
  area. The structure is accessible from userland via TLS, using the
  private get_user_thread() function.
* Introduced private userland functions [un]defer_signals(). They can be
  used to cheaply disable/re-enable signal delivery. They use the
  user_thread::defer_signals/pending_signals fields which are
  checked/updated by the kernel.

* Added BDiskDeviceRoster::GetDiskSystem() method, that can get a disk system
  by short/pretty/module name - since they should all be unique, I put them
  in a single namespace, please complain if you don't like that :-)
* Cleaned up DiskSystem.h and DiskDeviceRoster.h according to the updated
  header guidelines.
* Renamed ntfs pretty name from "ntfs File System" to "Windows NT File System".

arguments they get a single thread_creation_attributes structure now.

  which allow to specify the stack size or the stack to be used for the
  new user thread.

the C list mechanism which also makes the code nicer.

3dfe682f55 * Added some padding to the sem_t structure.
* Changed the semantics of unnamed semaphores. Before parent and child
  of a fork() would always share an earlier created semaphore. Now we do
  that only, if the "shared" parameter of sem_init() was true. That's
  still not quite the behavior Linux and Solaris have, but should be
  perfectly fine with how reasonable code would use the API.
* There's a global table for shared unnamed semaphores now. ATM a
  semaphore is leaked when no one explicitly destroys it (just as with
  named sems).
* Enforce per-team and global semaphore number limits.

8b1e3b1af8 - Implemented MediaExtractor::Copyright, which just calls the instantiated reader
- Implemented BMediaFile::Copyright, which just calls Copyright() of the extractor. So this is just a simple pass through.
- Style cleanup (mostly whitespaces)

Problem is that our readers currently return the copyright of the source code, not the copyright of the MediaFile itself, like the BeBook documents. Thus, we might need to change all readers to return appropiate data or behave differently for Haiku readers.

cdc00dadfc * Added optional {send,read}_data_no_buffer() hooks to the protocol
module interface. They directly operate on iovecs and thus allow
  protocols that don't need it to avoid the creation of a net_buffer.
* Adjusted the socket module to support the new hooks. If they are
  present, they will be chosen over the old hooks.

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.

ee96aa8f6e * Replaced cutex::release_count by flags field. It is only one thread
that can unlock the mutex, so one bit is sufficient.
* Added cutex_init_etc() which has an additional "flags" parameter.
  The only specifyable flag is CUTEX_FLAG_CLONE_NAME, which causes the
  function to strdup() the given name and free() its copy in
  cutex_destroy().
* cutex_destroy() does now unblock waiting threads.

8562499f44 * Introduced a new locking primitive I called "cutex" (sorry for the
name, couldn't resist :-P). It's semantically equivalent to a mutex,
  but doesn't need a semaphore (it uses thread blocking and a simple
  queue instead). Initialization can't fail. In fact it is ready to use
  without initialization when living in the bss segment, also in the
  early boot process. It's as fast as a benaphore in cases of low lock
  contention, and faster otherwise.  Only disadvantage is the higher
  immediate memory footprint of 16 bytes.
* Changed how the "thread" and "threads" debugger commands list the
  objects they are waiting for. Cutexes are also included.

  This removes a race condition when concurrent threads would notify at
  the same time.

801591dbde * Added an atomic_pointer_set() template function to util/atomic.h.
* Made the pointers const.
* Changed how the ARP module maintains its arp_entry::request_buffer: it
  now uses the atomic_pointer*() functions to make sure there is no race
  condition, and it's deleted only once.
* Getting an ARP entry would return uninitialized data, if the entry hadn't
  been resolved yet.

  {ADD,UPDATE}_PARANOIA_CHECK macros that imply the used "mode"

* Added TraceEntry::DumpStackTrace() callback which is supposed to print
  a stack trace for the entry, if it can do that.
* Added "--stacktrace" switch to the "traced" command, which causes the
  stack traces for all entries that have one to be printed as well.

  compatibility with BeOS. Though there shouldn't be many applications
  opening a pty, that we might be interested in...
