7e6ce1a3c5 Fix abort(3) to raise SIGABRT rather than causing SIGSEGV. 
tgkill() needs the .save stack unwinding directive to get the complete
stack trace.

Christopher Ferris
885f3b9cad Implement malloc_usable_size for debug impls. 
- Implemented chk_memalign.
- Fixed a few bugs in leak_memalign.
- Implemented {leak,fill,check,qemu}_malloc_usable_size.
- Make malloc_usable_size update at run time.
- Add malloc_test.cpp as a small set of tests for the
  malloc debug routines.
- Fix the qemu routines since it's been broken since it moved to C++.
- Add support for the %u format to the out_vformat in libc_logging.cpp.
  This is used by the emulator code.

Tested using the bionic-unit-tests with setprop libc.debug.malloc
set to 1, 5, and 10.

I tested as much as possible on the emulator, but tracing doesn't appear
to be working properly.

Bug: 6143477

Merge change from internal master.

Nick Kralevich
cf870199d5 FORTIFY_SOURCE: strcat / strncat optimize 
__strcat_chk and __strncat_chk are slightly inefficient,
because they end up traversing over the same memory region
two times.

This change optimizes __strcat_chk / __strncat_chk so they
only access the memory once. Although I haven't benchmarked these
changes, it should improve the performance of these functions.

__strlen_chk - expose this function, even if -D_FORTIFY_SOURCE
isn't defined. This is needed to compile libc itself without
-D_FORTIFY_SOURCE.

25a87f7641 Fix declaration of malloc_usable_size() 
The function should take a 'const void*' parameter, instead of 'void*'.
Note that the implementation in upstream-dlmalloc/malloc.c already does
this.
