9d16a79b18 Hide the symbol of helper function __libc_android_abort
Ideally __libc_android_abort would be static, but it could not be
because gcc would not allow calling a static function from an asm
statement.  Instead, using GCC visibility is work around.

cb7e8c5ef3 libc: update alarm() implementation to return 0 on error.
This matches the GLibc behaviour, and allows alarm(0xFFFFFFFF) to return 0.

519763265e libc: Fix sem_post() implementation to wake up all waiting threads.
This also allows us to optimize the case where we increment an
uncontended semaphore (no need to call futex_wake() then).

Also add missing declarations to misc. functions.
Fix clearerr() implementation (previous was broken).
Handle feature test macros like _POSIX_C_SOURCE properly.

b44fcd6e8f Fix for incorrect reply from sysconf(_SC_NPROCESSORS_ONLN)
When calling sysconf with _SC_NPROCESSORS_ONLN, the value one (1) was
returned on systems with two or more cores, since '/proc/stat' was
incorrectly parsed.

The function line_parser_getc (LineParser* p) read 128 characters of
input for each invocation.

The proper and probably aimed for behavior is to read 128 characters
at the first call, then for each subsequent call only return the next
buffered character until a new read is needed and only then read
another 128 characters.

Due to a flipped comparison between the two variables in_len and
in_pos that track the number of bytes of data read into the input
buffer and how much of it has been parsed, a new group of 128
characters were read at almost every call to line_parser_getc,
overwriting the still unhandled bytes from the previous call to
read. This caused the lines to be read to be sampled more than parsed.

d378c68d74 Fix spurious DNS lookups in the C library.
The problem was that the 'defdname' field of res_state structure
was not properly initialized in __res_vinit(). This field is used
to store the default domain name, which is normally build from
calling gethostname() (see line 549 of res_init.c).

Unfortunately, in the typical Android case, gethostname() returns
an error (the hostname is configured) and a random stack string is
used later to build the DNS search list (see lines 556+ in res_init.c)

For the sake of illustration, let's say the search list is set to
a random value like 'xWLK'.

The end result is that when trying to result an unknown domain name
(e.g. 'www.ptn'), the query fails then the resolver tries to make a
new query with the DNS search list path(s) appended (e.g. 'www.ptn.xWLK').

The patch simply initializes 'defdname' to an empty string to avoid
this when the net.dns.search system property is not set.

Also contains whitespace/formatting fixes

9f6915631b bonic: libc: cpuacct support for setuid functions
Any of the setuid functions now updates /acct/uid/ with its own tid
before changing users. This is so we can properly account for cpu time
per uid.

e31c1d0b48 Fix pread()/pwrite() stubs
On ARM EABI, 64-bit function parameters must be aligned
to an even/odd register pair.  The weird way these stubs
were written (using separate lo/hi parameters) prevented
this alignment from being enforced by the compiler.

6458c49c96 Fix ptsname_r(3) return type to match glibc
The gHardy man pages specify the return type of ptsname_r to be char*, but the
return value to be 0 on success, negative on error and the gHardy stdlib.h
defines extern int ptsname_r(...).

Busybox telnetd fails to run successfully without this change.

Merge commit '5f32207a3db0bea3ca1c7f4b2b563c11b895f276' into eclair-mr2-plus-aosp

* commit '5f32207a3db0bea3ca1c7f4b2b563c11b895f276':
  Wrap ARM abort() to improve stack trace.

5f32207a3d Wrap ARM abort() to improve stack trace.
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.

e36502673d fix [2170898] abort() doesn't print a stack tarce
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.
