943bec1287 * Made a class out of free_chunk.
* Fixed realloc() - "size" wasn't what I thought it would be.

840be9d6e6 Added __init_once(), an almost exact clone of pthread_once(), with the
difference that the initialization function has an additional void* argument,
so that it is suitable for initializing stuff in objects.

be62abafab * Use a condition variable when waiting for a syscall to be done calling.
* Use C++ DoublyLinkedList class instead of the struct list.
* Note, this code is untested yet, but I will test it now (Qemu doesn't work
  on Haiku anymore for some reason) :-)

258b34c594 * Fixed wrong parameter of lazy_mutex_destroy().
* Split locks.cpp into mutex.cpp, recursive_lock.cpp, and rw_lock.cpp (new
  subdirectory locks/).
* runtime_loader no longer includes the rw_lock, allowing removal of the TLS
  dependency again.

a4faebeb11 * Replace the FD used for fopendir() instead of closing the old one - according
to the specs, the application may still use the FD without changing its state,
  and only closedir() should finally close it.

ea77094b24 Replaced the hown-grown recursive lock implementation by a shared lazy
recursive lock. I haven't investigated it closer, but the previous
implementation was even broken -- "strace /bin/true" showed two
release_sem() calls, but no acquire_sem().

937b23cb21 Added locking primitive lazy_mutex, which has essentially the same behaviour
as a mutex, but allocates its semaphore lazily. This comes at the cost of an
additional atomic_add() when the semaphore has actually to be acquired, but
saves the semaphore creation completely in single-threaded programs and in
any program when there's no lock contention.

d78ffde5d1 * Some minor cleanup and improved comments.
* Fixed check in hoardSbrk(): resize_area() was invoked, even if the area was
  already large enough.
* Increased the initial heap size to 64 pages. Apparently the hoard
  implementation is rather generous and the first malloc() (caused by
  __init_heap()) already required enlarging the area.

* Added stub for mknodat().
* The kernel backend for faccessat() does not yet differentiate between
  effective and real user/group IDs, though.
* Removed B_ENABLE_INCOMPLETE_POSIX_AT_SUPPORT, as we now support everything
  (more or less). This also closes ticket #4928.

432bb91f34 * dir_vnode_to_path() now uses B_* error codes instead of POSIX ones, and also
returns the correct error code if the buffer was too small (should be ERANGE
  instead of ENOBUF).
* Also, it is now independent of B_PATH_NAME_LENGTH, and therefore should
  fulfill POSIX getcwd() requirements. This should also close ticket #3352.
* Is there any reason to allocate another buffer instead of using memmove()
  at the end instead of memcpy()?

5472c0c23e * The VESA driver now tries to find the PCI card that it is controlling by
checking the physical frame buffer location.
* This allows us to map the whole frame buffer at once, which means there is no
  need anymore to remap the memory on mode change.
* Also, this will ease the burden of the MTRRs, as the memory size will be
  properly aligned.

bb163c0289 * Added a set_mtrrs() hook to x86_cpu_module_info, which is supposed to set
all MTRRs at once.
* Added a respective x86_set_mtrrs() kernel function.
* x86 CPU module:
  - Implemented the new hook.
  - Prefixed most debug output with the CPU index. Otherwise it gets quite
    confusing with multiple CPUs.
  - generic_init_mtrrs(): No longer clear all MTRRs, if they are already
    enabled. This lets us benefit from the BIOS's setup until we install our
    own -- otherwise with caching disabled things are *really* slow.
* arch_vm.cpp: Completely rewrote the MTRR handling as the old one was not
  only slow (O(2^n)), but also broken (resulting in incorrect setups (e.g.
  with cachable ranges larger than requested)), and not working by design for
  certain cases (subtractive setups intersecting ranges added later).
  Now we maintain an array with the successfully set ranges. When a new range
  is added, we recompute the complete MTRR setup as we need to. The new
  algorithm analyzing the ranges has linear complexity and also handles range
  base addresses with an alignment not matching the range size (e.g. a range
  at address 0x1000 with size 0x2000) and joining of adjacent/overlapping
  ranges of the same type.

This fixes the slow graphics on my 4 GB machine (though unfortunately the
8 MTRRs aren't enough to fully cover the complete frame buffer (about 35
pixel lines remain uncachable), but that can't be helped without rounding up
the frame buffer size, for which we don't have enough information). It might
also fix #1823.

f89fd840a0 bonefish+stippi:
PThreads didn't have their array for the TLS values initialized.
From what we can tell, this would have been a problem for any program using
pthreads, but since all threads are pthreads now, it was much more likely to
be encountered. Like in Beam as reported in #4949 (which via libbind seems
to use some pthread stuff).
