9f17027980 assert.h: remove include guards
* including assert.h multiple times with NDEBUG varying is
  perfectly legal, and required by POSIX.

ec0190adb0 malloc_debug: Implement allocation dump on exit in guarded heap.
When enabled (using heap_debug_dump_allocations_on_exit(true) or
MALLOC_DEBUG=e) this causes a dump of all remaining allocations when
libroot_debug is unloaded. It uses terminate_after to be called as
late as possible.

When combined with alloc stack traces this makes for a nice if a bit
crude leak checker. Note that a lot of allocations usually remain
even at that stage due to statically, lazyly and globally allocated
stuff from the various system libraries where it isn't necessarily
worth the overhead to free them when the program terminates anyway.

158e20e60e malloc_debug: Implement alloc/free stack traces in guarded heap.
When configured to do so (using heap_debug_set_stack_trace_depth(depth)
or MALLOC_DEBUG=s<depth>) the guarded heap now captures stack traces on
alloc and free.

A crash due to hitting a guard page or an already freed page now dumps
these stack traces. In the case of use-after-free one can therefore see
both where the allocation was done and where it was freed.

Note that there is a hardcoded maximum stack trace depth of 50 and that
the alloc stack trace takes away space from the free stack trace which
uses up the rest of that maximum.

121655e9ee malloc_debug: Add default alignment option.
This allows for something similar as was implemented in 217f090 but
makes it optional and configurable.

The MALLOC_DEBUG environment variable now can take "a<size>" to set
the default alignment to the specified size. Note that not all
alignments may be supported depending on the heap implementation.

d1dc9cf655 stdint.h: use correct type for INT64_MAX (#11647)
int64_t is signed. Although it does not make a difference by itself, because
INT64_MAX is still a valid number for uint64_t (UL), the later INT64_MIN
declaration depends on INT64_MAX, and therefore got implicitly casted to
unsigned type.

This fixes the following program on a x86_64 system:

	#include <stdint.h>

	int main() {
		int64_t test = 5;
		if (test < INT64_MIN)
			return 1;
		return 0;
	}

This is a regression since commit 1d13a609 ("stdint.h: define [U]INT64[MAX|MIN]
with [U]L on x86_64").

c516bac9f4 Revert part of hrev24647
The baudrate constant for MIDI speed was after all the others in BeOS,
and we have to keep them with the same values for things to work.
Moreover, the constants in SerialPort.h were not changed, so everything
was out of sync and all apps using BSerialPort ended up using the wrong
speed.

Add a comment in termios.h to make sure this doesn't happen again.

afaa6ed4b3 x86[_64]: Randomize initial stack pointer on alternative signal stacks
If the alternate signal stack is used randomize the initial stack
pointer in the same way it is randomized on "normal" thread stacks.
Also, update MINSIGSTKSZ value so that regardless of where the new
stack pointer points to there is at least 4k of stack left.
