This reverts commit 754c178a.

Turns out we don't need it afterall (needed a stable sort anyways).
So, we'll make that change in the dev branch instead.

NOTE: This replaces qsort.c with the FreeBSD version. While
      the patch changes the source, it should not alter the
      implementation that should use the exact same algorithm.

The 64-bit data is not currently being used and more than doubles the size.

ZoneCompactor was using the system time zone database to get the offsets
instead of using the data it was compiling, so for newly added or recently
changed zones the index could be inconsistent with the data.

Affected zones: San_Luis, Casey, Davis, Mawson, Kathmandu, Novokuznetsk

use 64 bytes cache lines, reduce the main loop to 64-bytes instead of
128 bytes and adjust the prefetch distance to the optimal value.

* changes:
  bionic/linker: make the buddy allocator compute max_order on its own
  bionic/linker: change the buddy allocator to take a handle to the managed area

The code generated for Thumb and Thumb2 targets has different handling
for abort().  Because abort() is "noreturn", it doesn't need to preserve
the callee-save registers.  The Thumb2 version trashes LR and makes it
impossible to figure out who called abort().

This inserts a trivial stub function; net effect is stack traces are
reasonable after an abort().

For bug 2191452.

-- rename struct ba_info to struct ba
-- move the static ba descriptor from ba.c to linker.c and rename it ba_prelink
-- ba_init, ba_allocate, ba_free, ba_start_addr, and ba_len all take a pointer
   to struct ba

The lowest bit of the symbol's value should be ignored when looking at UNDEF symbols
for correctness. It is used as an ARM/Thumb flag by the linker.

the issue here is that abort() can be called from anywhere, in particular
from malloc or free. When we try to use the debug_log functions, these
can end up calling into some code (like malloc/free) that called abort()
in the first place and end up in an infinite recursion loop.

Do not submit this patch before the one that modifies the Android emulator to
work-around a weird ARMv7 emulation issue. This is done to temporarily re-allow
the -user builds needed for QA.

This is required to work-around some corny bugs in ARMv7 emulation.

The emulation itself is required to run the dex pre-optimization pass
for -user builds.

  Revert "Revert "bionic/linker: fix symbol lookup during relocations""

  Fix ABI breakage in libc.so and libm.so between 1.6 and Eclair.

This reverts commit 33acbf07.

372 MB/s for large transfers, 440 MB/s for smaller ones down to 1KB. 130 MB/s for very small transfers ( < 32 bytes )
Performance is similar with non-congruent buffers.

This reverts commit 8d0c0334.

  bionic/linker: fix symbol lookup during relocations

When resolving relocations while loading a library, the linker used to find
symbols by looking them up in the list of all linked libraries for the current
process, as opposed to following just the library's DT_NEEDED entries.  This
can cause a problem where the symbol is picked up from the wrong library.

* changes:
  Add pthread_mutex_lock_timeout_np

This is used to perform a mutex lock for a given amount of
milliseconds before giving up. Using the _np prefix since this
is absolutely not portable.

Also remove a compiler warning in pthread_attr_getstackaddr

For performance reasons, we don't call the kernel helper. Instead, we directly
access the TLS register on ARMv6 and higher. For ARMv5TE, keep using the hard-coded
address populated by the kernel on each task switch.

NOTE: Since we don't call the kernel helper, this must precisely match your
      kernel configuration. This is controlled by setting the ARCH_ARM_HAVE_TLS_REGISTER
      variable to 'true' in your board configuration file.
