Also make sysconf use PTHREAD_STACK_MIN rather than redefining its
own, different, constant.

off_t is signed to support seeking backwards, but that's a liability
when using off_t to represent a subset of a file.

Restoring DEFAULT_MMAP_THRESHOLD to 64k, the way it was before
999089181e.
This forces allocations in the 64k-256k range to be mmaped.

Yet another archaic relic containing bugs that had been fixed years before the
Android project even started...

This updates the MIPS arch to be much more in
sync with the commit Nick Kralevich made last
June; see 9d40326830.
Rewrite
crtbegin.S -> crtbegin.c
crtbegin_so.S -> crtbegin_so.c
__dso_handle.S -> __dso_handle.c
__dso_handle_so.S -> __dso_handle_so.c
atexit.S -> atexit.c
Previously __do_global_dtors_aux was in the tasks
__FINI_ARRAY__ linked with crtbegin.S and it now being
removed as there is no need to call a destructor just
before terminating a process.
Shared libraries, on the other hand, are linked with
crtbegin_so.c and have a hidden destructor declared
to allow the bionic linker to call __on_dlclose().

This reverts commits eb1b07469f and
d14dc3b87f, and fixes the bug where
we were calling mmap (which might cause errno to be set) before
__set_tls (which is required to implement errno).

Tested using a static version of the strlen libc_test program
on a nexus7 that uses the generic code.
Merge from internal master.

This optimized version is primarily targeted at cortex-a15.
Tested on all nexus devices using the system/extras/libc_test strlen test.
Tested alignments from 1 to 32 that are powers of 2.
Tested that strlen does not cross page boundaries at all alignments.
Speed improvements listed below:
cortex-a15
- Sizes >= 32 bytes, ~75% improvement.
- Sizes >= 1024 bytes, ~250% improvement.
cortex-a9
- Sizes >= 32 bytes, ~75% improvement.
- Sizes >= 1024 bytes, ~85% improvement.
krait
- Sizes >= 32 bytes, ~95% improvement.
- Sizes >= 1024 bytes, ~160% improvement.
Merge from internal master.
