47a20cd6d1 M68K: turn #warnings into comments in public headers
The warnings made those headers and those including them not detectable
by libiberty's configure because of the way it checked for them.

This fixes the gcc build.

93ea83e53d Allow custom baud rates for FTDI serial ports
- Termios: cf{get,set}{i,o}speed can handle arbitrary speed values.
- The value is stored in the appropriate fields of the termios structure
  in this case. The old constants (stored in the flags) are preserved
  for BeOS binary compatibility.
- Adjust the FTDI FT232* driver to accept custom rates, by replacing the
  hardcoded regster values with a function that will compute it
  according to FTDI documentation (confirmed giving the same values for
  the existing baudrates).

7aebec8db1 libroot: Undefine constants for unsupported POSIX features
Haiku does not yet support certain features related to POSIX threads.
Constants used to test for the presence of these features should
therefore be left undefined, according to the POSIX spec, but are
currently set to -1. This can cause software built on Haiku to
incorrectly detect the presence of these features.

* unistd.h: Undefine _POSIX_THREAD_ATTR_STACKADDR,
  _POSIX_THREAD_PRIORITY_SCHEDULING feature constants.
* conf.cpp: __sysconf: Return -1 for unsupported features.

dbf060a3f7 libroot: Add brk() and sbrk().
This commit replaces the placeholder implementation of sbrk(), which
operated on a process' heap, with real implementations of brk() and
sbrk() that adjust a process' program break.

* unistd.h: Add standard definitions of brk() and sbrk(); include
  stdint.h for intptr_t.
* thread.cpp: Recognize RLIMIT_AS and RLIMIT_DATA resource limits
  (both currently unlimited); order limit identifiers alphabetically.
* arch-specific.cpp: Remove sbrk_hook().
* malloc_debug_api.cpp: Remove sbrk_hook().
* unistd/Jamfile: Build brk.c instead of sbrk.c.
* unistd/brk.c: Add.
* unistd/sbrk.c: Delete (placeholder implementation).
* libroot_stubs.c: Remove sbrk_hook().
* libroot_stubs_legacy.c: Remove sbrk_hook().
* src/tests/.../posix/Jamfile: Build brk_test.c.
* brk_test.c: Add (simple unit test that demonstrates behaviour of
  sbrk()).

75d1eb3a59 assert.h: reintroduce headers guard for function declarations.
The POSIX standard requires us to allow assert.h to be included multiple
times with differnt values of NDEBUG. So we can't have a global header
guard on the files. However, we must also make sure that we don't
declare functions multiple times in that case. Re-introduce an header
guard on the part of the file where we declare functions, only.

Fixes lots of warnings when building Netsurf.

8d2aee6bc8 libbind: integrate "netresolv" patches from NetBSD.
libbind development was transferred to the NetBSD project at
http://wiki.netbsd.org/individual-software-releases/netresolv/

There isn't an official release yet, but they provide a set of patches
against the latest libbind release.

* Remove all files we don't use
* Merge the changes to the remaining files
* Add some new files we need
* Move getifaddrs implementation to libnetwork (instead of libbnetapi)
so it can be used by netresolv.

Fixes #8293 : netresolv uses getifaddrs to determine if there is a local
IPv6 address. If there is not, it will not return AAAA records.

* Fixes sharing semantics, so non-shared semaphores in non-shared
  memory do not become shared after a fork.
* Adds two new system calls: _user_mutex_sem_acquire/release(),
  which reuse the user_mutex address-hashed wait mechanism.
* Named semaphores continue to use traditional sem_id semaphores.

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").

Moreover, the constants in SerialPort.h were not changed, so everything

speed.
