- Reimplemented mutex to use the _kern_mutex*() syscalls.
- The initializer functions cannot fail anymore -- changed their return type
to void.
- Changed the initializer function semantics to not copy the name by default
anymore (as in the kernel). Also added *_etc() versions of them that take an
additional flags.
- Added static initializer macros.
- Made the mutex (and thus recursive_lock) lock functions non-interruptable.
- Got rid of the "lazy" version. They are no longer needed, since the
initialization of the standard types can be done statically and cannot fail.
* Adjusted libroot, runtime loader, and other code using the private libroot
locking primitives to the new semantics.
* pthreads mutexes and condition variables:
- Reimplemented using the _kern_mutex*() syscalls.
- Consistently use POSIX error codes.
- Fixed some not quite POSIX compliant behavior.

keeping all returned heap memory in the 0xdeadbeef state (including the
first sizeof(void *) bytes otherwise for the free list). While wasting a lot
of memory it allows you to rely on 0xdeadbeef being always present as no
future allocation will reuse the freed memory block.
* Also added heap_debug_malloc_with_guard_page() which is intended to allocate
a memory block so it is aligned that the start of invalid memory past the
allocation is in an unmapped guard page. However the kernel backend that would
guarantee this is not yet implemented, so right now this works only by chance
if no other area happens to be allocated exactly past the created one. With a
very specifc suspicion you can put that one allocation you get to good use
though. It causes a crash when accessing memory past the allocation size so
you actually get a backtrace from where the access happened instead of only
after freeing/wall checking.

* Make the contiguous page allocation capable of aligning the allocation
and make it more clever by checking up front if there's a chance of getting
enough pages at all, by giving up earlier if the page count can't be fit
anymore, and in the alignment case by only checking the pages which have a
valid alignment.
* If the alignment requirement is > B_PAGE_SIZE we now use page allocation
directly, because the bins aren't necesarily aligned on their size past
B_PAGE_SIZE anymore.
* When doing aligned bin allocation, calculate the aligned size up front and
choose the right heap for the allocation.
* Also when doing aligned bin allocations we not only need to round up the size
but also ensure that the bin we choose is aligned at all.
* Moved adding leak check info into it's own function.
Fixes various misalignment problems when working with alignments > B_PAGE_SIZE
or when using alignments < allocation size. Also the directly aligned page
allocations now only use up as many pages as actually required instead of
allocating based on the rounded up to align size.

When initializing driver settings, make sure to set the parameter count to 0,
because these settings have not been parsed yet. This allows us to safely free
the settings. Freeing the settings is triggered in load_driver_settings() if
we encounter settings which have been originally loaded by the boot_loader,
which might be stale. I think the bug would trigger for settings which had been
loaded by the boot_loader but had never been parsed.

sHeapBase will probably not point to memory in the heap area. Use
sFreeHeapBase instead.
* When reserving the heap area range fails, set sHeapBase to NULL, so we'll
later know about the fact.
* hoardSbrk(): When resizing the area fails, we'll now try to allocate a new
one, if the former failure was not due to an "out of memory" situation.
E.g. if the heap range reservation failed or, if we just have exhausted the
range, another area could be in the way. Also when mmap()ing over
malloc()ed, the heap area count be split in two with the first part
retaining the old area ID, thus preventing resizing as well. Fixed#5168.

capabilities to aid in debugging memory corruption issues.
It does:
* Initialize memory to 0xcc to help turn up use of uninitialized memory
* Set freed memory to 0xdeadbeef to help find accesses of freed memory
* Use the paranoid heap validation to turn up many cases of memory corruption
* Use a simplistic wall check to turn up memory overwrites past allocations
* Take extra steps to validate freed addresses to turn up misaligned frees
It has an interface to en-/disable paranoid validation and to start/stop regular
wall checking. Both are currently just enabled. At a later stage a debug version
of libroot could be used by an application and the checks enabled at will. Note
that due to the paranoid validation and the suboptimal locking this allocator
will perform horribly. Still to find memory corruption issues in the system or
also in your applications it can be helpful to build your installation with it
turned on. To enable it you currently need to edit the Jamfile to sub-include
the malloc_debug instead of the malloc directory.
