39b1f6172a Move _obstack_compat out of common
it is impossible to create an alias of a common symbol (as
compat_symbol does), because common symbols do not have a section or
an offset until linked.  GNU as tolerates aliases of common symbols by
simply creating another common symbol, but other assemblers (notably
LLVM's integrated assembler) are less tolerant.

2a26ef3a01 Add HAVE_MREMAP for mremap usage
Introduce (only on Linux) and use a HAVE_MREMAP symbol to advertize mremap
availability.

Move the malloc-sysdep.h include from arena.c to malloc.c, since what is
provided by malloc-sysdep.h is needed earlier in malloc.c, before the inclusion
of arena.c.

e19af3803b muntrace: reset file and hooks before finalizing the stream
fclose will call free, invoking its hook, then fprintf which would indirectly
try to allocate a buffer, and this can cause malloc to be used (thus its hook
to be invoked) if libio uses malloc instead of mmap; given any malloc/free hook
locks the internal lock, this leads to a deadlock.

To prevent this hook roundtrip at muntrace, first unset MALLSTREAM and the
hooks, and only after that close the trace file.

9fab36eb58 Shrink heap on linux when overcommit_memory == 2
Using madvise with MADV_DONTNEED to release memory back to the kernel
is not sufficient to change the commit charge accounted against the
process on Linux.  It is OK however, when overcommit is enabled or is
heuristic.  However, when overcommit is restricted to a percentage of
memory setting the contents of /proc/sys/vm/overcommit_memory as 2, it
makes a difference since memory requests will fail.  Hence, we do what
we do with secure exec binaries, which is to call mmap on the region
to be dropped with MAP_FIXED. This internally unmaps the pages in
question and reduces the amount of memory accounted against the
process.

6ef9cc37f0 Return requested size for malloc_usable_size when MALLOC_CHECK_ > 0
[BZ #1349]

malloc_usable_size returns the usable size in an allocated chunk,
which may be >= the requested size. In the case of MALLOC_CHECK_ being
exported to > 0 however, only the requested size is usable, since a
magic value is written at the end of the request size to trap writes
beyond request bounds. Hence, when MALLOC_CHECK_ is exported to > 0,
malloc_usable_size() should return the request size.

f0c1dedf0d Fix tst-obprintf - and mcheck in general
tst-obprintf failed with GCC 4.7.

It turned out that this is the fault of GCC optimizing away the
following from malloc/mcheck.c:
      /* We call malloc() once here to ensure it is initialized.  */
      void *p = malloc (0);
      free (p);

gcc sees the malloc(0);free pair and removes it completely.

And now malloc is not properly initialized and we screw up if both
mcheck is used (via tst-obprintf) and MALLOC_CHECK_ is set (as it is in my
environment).
