6607b17d6b Pimped up the "caches" command. Now it prints the caches in trees with
additional info (offset, size, used pages, areas), sorting the trees
by used pages.

5e3a974d1e * When KERNEL_HEAP_LEAK_CHECK is enabled we also store the calling
function requesting the allocation.
* The "allocations" commands does also print the caller and can filter
  by caller, now.
* Added new "allocations_per_caller" command, which sums up allocations
  per caller and prints them in a table sorted by size or count.

0f448d21e5 * Added vm_page_write_modified_page_range(), which is similar to
vm_page_write_modified_pages(), save that it only writes pages in the
  given range.
* Added vm_page_schedule_write_page_range() which schedules all modified
  pages in the given cache's range for writing by the page writer.
* Added _kern_sync_memory() syscall and the msync() POSIX function.

403bfdda6c * The floating point output now correctly honours eventual sign flags,
and actually shows the sign (before, it would just absorb it).
* On calling floating() from vsnprintf(), the order of the "fieldWidth", and
  "flags" parameters were mixed, causing some strange output.
* Minor cleanup.

15173df4e9 Last patch of the vm86 patch series from Jan Klötzke - thanks!:
* The new function vm86_do_int(struct vm86_state *state, uint8 vec) provides a
  facility to call BIOS interupt handlers. The function must only be called from
  a user thread context because the lower 1MB of the address space is used.

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.

c44fb2a62c Advisory locking fixes:
* Made the access strategy to vnode::advisory_locking consistent.
  get_advisory_locking() was guarding it with sVnodeMutex,
  create_advisory_locking() was using atomic_pointer_test_and_set(), and
  release_advisory_lock() just set it unguardedly. We do use sVnodeMutex
  consequently, now.
* Beautified create_advisory_locking() (got rid of the gotos,
  reorganized the control flow).
* Fixed race conditions in acquire_advisory_lock(). It was always
  unlocking and relocking the advisory_locking object when it didn't
  have to wait, but in the meantime someone else could have changed the
  locking situation. Reorganized the control flow, so that it only drops
  the lock when it has to fail or wait. Using create_advisory_locking()
  upfront simplifies the code quite a bit (and fixes another race
  condition).

APR's testprocmutex test seems happy now, at least.

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.
