This patch fixes a known bug in bionic libm
due to aliasing issues in gcc 4.2 and 4.4; more
specifically in frexpf.
The function frexpf is used to extract the
mantissa and exponent from a double precision number.
The bug has already been reported here:

Originally, there are _rand48 (in libc/bionic/_rand48.c) and __rand48
(in libc/stdlib/_rand48.c) implemented in bionic. Besides the naming,
the functionality is identical. This patch removes the duplicated
_rand48. Also, drand48 and erand48 are modified accordingly.

Although header libc/stdio/local.h declares the macros and private
variables of stdio, there are several internal symbols exposed
unexpectedly.
Change-Id: Ie7a07f85b70322fb9cd05b3c8e1bcc416061eb4b
The change explicitly isolates the assembly-only macros in header
<machine/cpu-features.h> in order to prevent mis-inclusion in C/C++
source files.

In order not to conflict with the symbols defined in file
libc/netbsd/getaddrinfo.c, this patch makes the internal/helper
functions static.

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.

1. Make the feature test work by excluding known-deficient processors, so
we don't have to maintain a complete list of all the processors that support
REV and REV16.
2. Don't abuse 'register' to get an effect similar to GCC's +l constraint,
but which was unnecessarily restrictive.
3. Fix __swap64md so _x isn't clobbered, breaking 64-bit swaps.
4. Make <byteswap.h> (which declars bswap_16 and friends) use <endian.h>
rather than <sys/endian.h>, so we get the machine-dependent implementations.

ARMv6 ISA has several instructions to handle data in different byte order.
For endian conversion (byte swapping) of single data words, it might be a
good idea to use the REV/REV16 instruction simply.

With this patch _and_ an upcoming build/ patch, the destruction
of static C++ objects contained in shared libraries will happen
properly when dlclose() is called.
Note that this change introduces crtbegin_so.S and crtend_so.S which
are currently ignored by the build system.
+ move definition of __dso_handle to the right place
(before that, all shared libraries used the __dso_handle
global variable from the C library).
Note that we keep a 'weak' __dso_handle in aeabi.c to avoid
breaking the build until the next patch to build/core/combo/
appears. We will be able to remove that later.
+ move bionic/aeabi.c to arch-arm/bionic/ (its proper location)
NOTE: The NDK will need to be modified to enable this feature in
the shared libraries that are generated through it.

Add ip6t_get_target() to kernel_known_generic_statics in
libc/kernel/tools/defaults.py to be able to build ip6tables.

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.
