Upgrade fnmatch.c from OpenBSD version 1.13 to 1.16.
This is needed primarily to address CVE-2011-0419.
This is a straight copy from upstream's version at
http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/gen/fnmatch.c and
incorporates the following changes:
Revision 1.16:
New fnmatch(3) implementation which is not recursive.
Written and provided under BSD licence by William A. Rowe Jr.
Originally released in Apache APR-1.4.5.
Merged class matching code from r1.14 and PATH_MAX check from r1.15.
ok miod millert
Revision 1.15:
Put a limit on recursion during matching, and reject input of size greater
or equal PATH_MAX. Based on similar fix made in NetBSD.
ok miod@ millert@
Revision 1.14:
POSIX character class support for fnmatch(3) and glob(3). OK deraadt@
Version 1.14 introduced charclasses.h, which we copy unmodified
from upstream version 1.1.

cdefs.h: Introduce the __purefunc attribute, which allows us to mark
certain functions as being "pure".
http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html
Many functions have no effects except the return value and their
return value depends only on the parameters and/or global variables.
Such a function can be subject to common subexpression elimination
and loop optimization just as an arithmetic operator would be.
string.h: Mark many commently used string functions as "pure", to
allow for additional compiler optimizations.

This change will automatically post-process kernel headers
specified by device, board, and product. This will allow us
to not check in each kernel header twice, at least for the
device specific headers for now.

New functions:
tfind
tsearch
tdelete
twalk
tdestroy (GNU extension)
Bug fix: the current implementation for realpath would crash
if the second argument (resolved_path) is NULL.
New headers:
ar.h
search.h

When the dynamic linker loads a shared library into memory, it
initially allocates a chunk of memory. The memory is then carved
into smaller chunks for each LOAD region, and appropriate memory
protections applied.
Modify the initial memory allocation so that the pages are mapped
as PROT_NONE, rather than PROT_READ / PROT_EXEC. This ensures that
gaps between LOAD regions are not inadvertantly readable / executable.
(Long term, we should munmap() these gaps entirely)

After forking, the kernel_id field in the phtread_internal_t returned by pthread_self()
is incorrect --- it's the tid from the parent, not the new tid of the
child.
The root cause is that: currently the kernel_id is set by
_init_thread(), which is called in 2 cases:
(1) called by __libc_init_common(). That happens when the execv( ) is
called after fork( ). But when the zygote tries to fork the android
application, the child application doesn't call execv( ), instread, it
tries to call the Java main method directly.
(2) called by pthread_create(). That happens when a new thread is
created.
For the lead thread which is the thread created by fork(), it should
call execv() but it doesn't, as described in (1) above. So its kernel_id
will inherit the parent's kernel_id.
Fixed it in this patch.

If we catch a fatal signal that won't automatically re-throw when
the thread resumes, re-throw it manually. (Common examples are
SIGPIPE and the SIGFPE from integer division by zero.)

This reverts commit 94a85f6636
There is a smoke test failure for Prime but Crespo/Stingray are fine. Will revert the change for now until further investigation is made.
Update wire protocol to return and process error code first.
This will make sure dns proxy operations do not stall when
an internal error happens.
Also fix a compiler warning.
Also fix a potential buffer overflow.
And use correct types (uint32_t) rather than int when reading from network.

This adds the thread id and name to the "Fatal signal" logging,
making it easier to track down where in process it actually crashed.

Add support for PT_GNU_RELRO. This allows the static linker to
indicate that certain regions of memory should be marked as
"read-only" after dynamic linking is complete.
See:
* http://www.akkadia.org/drepper/nonselsec.pdf (section 6)
* http://tk-blog.blogspot.com/2009/02/relro-not-so-well-known-memory.html
Note that this change has no effect on Android right now, because
we don't compile our code with relro enabled.

Summer time in Cuba has been delayed 3 weeks (now starts April 1 rather
than March 11). Since March 11 (the old start date, as listed in 2012a)
is just a little over a week away, this change is urgent.
