d129070196 Release the fork lock when _kern_fork() failed or otherwise we'll
deadlock when trying the next fork().

a8af2b6dda Some work on pthreads:
* Made the pthread_cond_t internals public. This is necessary to support
  process shared condition variables. Fixed initializer macro.
* Made the pthread_rwlockattr_t structure opaque.
* pthread_t is no longer typedef'ed to int. It's the pointer to the
  internal _pthread_thread structure.
* Removed __get_pthread(). pthread_self() can be used instead.
* No longer tunnel the pthread exit value through Haiku's thread exit
  value. We do have a separate field in the _pthread_thread structure
  for it, now.
* Handle detaching of threads correctly.
* pthread_rwlockattr_{g,s}etpshared() use the
  PTHREAD_PROCESS_{SHARED,PRIVATE} constants, now.
* Commented out yet unsupported structures (barriers, spinlocks).
* Rebuilt APR optional package. The pthread changes weren't binary
  compatible.

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).

3ca1072d44 * Reimplemented pthread_once. The old one was neither thread-safe nor
particularly efficient.
* pthread_mutex implementation:
  - Removed the pthread_mutex_t indirection (the type was a pointer to
    the actual structure which was allocated on the heap), as it made
    sharing the mutex between processes impossible.
  - Removed the distinction between process shared and non-shared
    mutexes. Benaphores work just as well in shared memory, so we always
    use them.
* Fixed some static initializer macros. PTHREAD_COND_INITIALIZER is
  still broken, since it doesn't work in C code.

eb1a8c446e siglongjmp() calls __longjmp_return() also on x86, now. This resets the
signal mask as required. and also makes my recent return value fix
unnecessary, since __longjmp_return() already does that.

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.

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.

  provide private functions.

  with respect to the lifespan of the key specific values.
* It supports up to 256 different keys, which is equivalent of the solution
  that FreeBSD offers.

3cf7ecd1e4 * Added <sys/mman.h> header. It declares only mmap() and munmap() yet
and defines the macros needed by them.
* Renamed syscall sys_vm_map_file() to _kern_map_file() and changed the
  path to an FD parameter. Changed vm_map_file() accordingly and
  adjusted the kernel ELF loader and the runtime loader.
* Added syscall _kern_unmap_memory().
* Added bool unmapAddressRange parameter to vm_create_anonymous_area()
  and map_backing_store(). If true and the address specification is
  B_EXACT_ADDRESS, all areas in the specified address range will be
  deleted (unless an area is covered only partially).
* Introduced B_SHARED_AREA flag, which is set on areas that have been
  created by {vm,_user}_map_file() with REGION_NO_PRIVATE_MAP. When
  fork()ing those areas won't be copied CoW, but rather be cloned. This
  is needed for mmap() MAP_SHARED.
* {vm,_user}_map_file() also accept an FD argument < 0, in which case an
  anonymous area is created.
* Implemented mmap() and munmap(). Currently there's the restriction
  that we can't partially unmap areas. Otherwise the functions should be
  rather compliant. We also support the non-POSIX extension
  MAP_ANONYMOUS.

7ffafac8d7 * Reorganized the FS interface a little:
- Moved most file_system_module_info hooks into separate structures.
    Those that operate on mounted volumes to fs_volume_ops, those
    operating on a vnode to fs_vnode_ops.
  - Got rid of the fs_volume, fs_cookie, fs_vnode typedefs. We use void*
    again.
  - Instead of a void* volume and node cookie hooks are passed a
    fs_volume and fs_vnode structure pointer, which contain the cookie
    and an ops pointer (fs_volume a few more things).
  - The VFS {new,publish,get,...}_vnode() functions take a fs_volume*
    instead of the volume ID. So does vfs_get_fs_node_from_path().
  - Added type and flags arguments to publish_vnode() and the
    get_vnode() hook and removed the type argument from lookup() hook.
    Added vnode::type using formerly unused bits to store the node type.
    Simplified a few things in the VFS due to the now always available
    node type.
  - Added fs_volume_ops::{create,delete}_sub_vnode() and
    fs_vnode_ops::get_super_vnode() hooks. They are used to support file
    system layers, e.g. allowing to extend an FS not supporting BeOS
    attribute with attribute support. Needs some more work in the VFS.
  - Added fs_vnode_ops::create_special_node() hook for creating special
    nodes (e.g. FIFOs).
* Adjusted the built-in file systems and BFS according to the interface
  changes. Removed all other FSs from the image for the time being.
  We'll see whether further API changes are necessary before porting
  them.
* Adjusted the bfs_shell accordingly.
* Implemented create_special_node() in rootfs to support special nodes.
* Added support for FIFOs:
  - Added syscall _kern_create_fifo() (used by mkfifo()), which creates
    a special node (type S_IFIFO) in the respective file system.
  - When a special node is published the VFS creates a respective sub
    node. Currently only FIFOs are supported.
  - Added a little support for FIFO subnodes by using functionality from
    the pipefs.
  - Added mkfifo to the image. It can create FIFOs in the rootfs, but
    the FIFOs aren't really usable ATM, since they still work like
    pipes, i.e. readers and writers need to have them open at the same
    time.
* Some smaller changes in the VFS:
  - Made the *_CALL macros nicer to use (vargs).
  - Refactored FS entry lookup into new function lookup_dir_entry().
  - create_vnode() no longer just calls the FS create() hook. First it
    looks up the entry and uses open_vnode(), if it already exists. This
    is necessary for two reasons: 1) The FS might not support create()
    while still allowing to open() entries. 2) When the FS has other
    layers on to of it (or the respective node) it might not be
    responsible for opening the node.
