183ad9df53 Allow sharing the RELRO section via a file.
Add flags and a file descriptor to android_dlopen_ext() to allow writing
the RELRO section of the loaded library to a file after relocation
processing, and to allow mapping identical pages from the file over the
top of relocated memory in another process. Explicitly comparing the
pages is required in case a page contains a reference to a symbol
defined in another library loaded at a random base address.

12bbb91645 Support loading libraries to a reserved address.
Add flags and parameters to android_dlopen_ext() to allow loading a
library at an already-reserved fixed address. If the library to be
loaded will not fit within the space reserved, then the linker will
either fail, or allocate its own address space as usual, according to
which flag has been specified. This behaviour only applies to the
specific library requested; any other libraries loaded as dependencies
will be loaded in the normal fashion.

There is a new gtest included to cover the functionality added.

012cb4583a Add android_dlopen_ext() interface to linker.
Add a function "android_dlopen_ext()", defined in <android/dlext.h>.
This is an extended version of dlopen() which takes a struct for passing
additional parameters for Android-specific functionality. This will be
used to support RELRO section sharing between separate processes.

40b0579127 Add iswblank for libcxx.
We have similar degenerate implementations for all the other isw* functions,
so it's weird to exclude just one.

02c78a3867 Reimplement isinf/isnan/fpclassify.
Also move isinf and isnan into libc like everyone else.

Also move fpclassify to libc like the BSDs (but unlike glibc). We need
this to be able to upgrade our float/double/long double parsing to gdtoa.

Also add some missing aliases. We now have all of:

  isnan, __isnan, isnanf, __isnanf, isnanl, __isnanl,
  isinf, __isinf, isinff, __isinff, isinfl, __isinfl,
  __fpclassify, __fpclassifyd, __fpclassifyf, __fpclassifyl.

5eb670462a Replace the bionic hack for a vfprintf leak with (roughly) the upstream fix.
Currently in bionic free and freedtoa are equivalent, but that's not true
of gdtoa. This makes it easier to test gdtoa without having to replace
everything. (Yes, I found this bug the hard way.)

fe6adbad19 Upgrade to tzdata2014b.
From the release notes:

  Changes affecting near-future time stamps

    Crimea switches to Moscow time on 2014-03-30 at 02:00 local time.
    (Thanks to Alexander Krivenyshev.)  Move its zone.tab entry from UA
    to RU.

    New entry for Troll station, Antarctica.  (Thanks to Paul-Inge
    Flakstad and Bengt-Inge Larsson.)  This is currently an
    approximation; a better version will require the zic and localtime
    fixes mentioned [in the full release notes], and the plan is to wait
    for a while until at least the zic fixes propagate.

edd7c2ec25 Fix the printf issue for 64 bits. The following case:
printf("%1$s %1$s\n", "test");

would print garbage instead of the second "test". The problem is __find_arguments
and the patch is a backport of two patches from OpenBSD that fix the issue:

Author: tedu <tedu@cvs.openbsd.org>
Date:   Sat Apr 29 23:00:24 2006 +0000

    check mmap for failure.  the helper functions using it return -1, but
    callers do not yet check since printf() for example is not documented
    to return an error.
    some formatting cleanups.
    mostly ok deraadt millert

Author: millert <millert@cvs.openbsd.org>
Date:   Fri May 16 14:28:54 2008 +0000

    C99 says that for each va_copy() there must be a matching va_end().
    Replace the non-portable hackery in __find_arguments() with a union.
    From FreeBSD.

473d06707b Fix the POSIX timers fix.
If we're not going to wait for the timer threads to exit, we need
another way to ensure that we don't free the data they're using
prematurely. The easiest way to ensure that is to let them free the
data themselves.

Replace _mark with netid.

Mark sockets used to test IPv4/IPv6 support as well as sockets
used to determine source address for rfc6724 sort.

Remove pid/uid mappings (functionality moved to system/netd).

Do not create resolv_cache when it does not exist, but rather only
when DNS configuration is supplied.

Clean up unused functions.
