* 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.

* changes:
  Fix an infinite loop in time2sub.

The problem is that time_t is signed, and the original code relied on the
fact that (X + c < X) in case of overflow for c >= 0. Unfortunately, this
condition is only guaranteed by the standard for unsigned arithmetic, and
the gcc 4.4.0 optimizer did completely remove the corresponding test from
the code. This resulted in a missing boundary check, and an infinite loop.

The problem is solved by testing explicitely for TIME_T_MIN and TIME_T_MAX
in the loop that uses this.

Also fix increment_overflow and long_increment_overflow which were buggy
for exactly the same reasons.

Note: a similar fix is needed for system/core/libcutils

  bionic/linker: keep track of opened libraries by basename

Merge commit '22b5eb85'

* commit '22b5eb85':
  linker: remove newlines from DL_ERR so that dlerror works correctly

Prior to this change, the dynamic loader kept track of opened libraries
either by their base name (i.e., libfoo.so instead of /system/lib/libfoo.so)
when the shared library was loaded through the DT_NEEDED tag in an ELF header,
or by whatever name was passed to dlopen(). This created a number of problems,
among which:

1. dlopen("libfoo.so") and dlopen("/path/to/libfoo.so") would open the same
library twice;
2. dlopen("/path/to/libfoo.so") and then dlopen("libbar.so"), where libbar.so
depends on libfoo.so, would open libfoo.so twice.

This patch makes the dynamic loader keep track of each loaded library by
basename, which resolves the above ambiguity. The patch also enforces
library lookup by base name, which means that it will refuse to load another
library that has the same name.

Thanks for the inspiration Iliyan.

  Make the DNS resolver accept domain names with an underscore.

More precisely, this accepts domain labels with an underscore in
the middle (i.e. not at the start or the end of the label). This
is needed to perform complex CNAME chain resolution in certain
VPN networks.

  Restore malloc debug.

Some libc changes were preventing the initialization call from being made.
The basic problem appears to be that libc_init_common.c is only built once,
and it's only built for the non-debug libc.
