In practice, with this implementation we never need to make a system call.
We get the main thread's tid (which is the same as our pid) back from
the set_tid_address system call we have to make during initialization.
A new pthread will have the same pid as its parent, and a fork child's
main (and only) thread will have a pid equal to its tid, which we get for
free from the kernel before clone returns.
The only time we'd actually have to make a getpid system call now is if
we take a signal during fork and the signal handler calls getpid. (That,
or we call getpid in the dynamic linker while it's still dealing with its
own relocations and hasn't even set up the main thread yet.)

Parts of this are just getting us in sync with upstream, but the
'const' stuff is our own mess. We should kill the *_tz functions
and lose this difference from upstream.

This brings us closer to upstream's ToT localtime.c; our main interest
being their alternative fix for the stack usage we addressed in commit
8a8b0c9bfc.

On Nakasi builds, /system/bin/tf_daemon is a pre-compiled
vendor supplied binary. When support for non-PIE executables
was removed, that daemon failed to start, which induced
a number of bugs.
* keystore is broken
* CTS runs will hang after a certain period of time
Temporarily reenable non-PIE support for 32-bit platforms
until Nakasi is fixed.
This rolls back the following commits:
Cleanup: updated comments
* 6275f20834
Cleanup: remove AARCH/ARM_COPY relocation support
* b906e13c55
And restricts the following patch to 64 bit only:
Remove support for non-PIE executables

This allows an easier way to share config parameters between unit tests
and the bionic code.
It also fixes a problem where the 32 bit bionic tests based on glibc, or
the cts list executable did not have the pvalloc,valloc tests.

Rename jemalloc.cpp to jemalloc_wrapper.cpp to avoid problems with
the libc library having two jemalloc.o files that clobber each other.

The C library didn't export the 'index' symbol, but its C++ name-mangling
instead, which broke the ABI and prevented some applications from loading
properly.
The main reason was that the implementation under bionic/index.cpp relied
on the declaration to specify that the function has C linkage.
However, the declaration for index() was removed from both <string.h>
and <strings.h> in a recent patch, which made the compiler think it was
ok to compile the function with C++ linkage instead!
This patch does the following:
- Move index() definition to bionic/ndk_cruft.cpp and ensure it uses
C linkage.
Note that this removes index() from the 64-bit library entirely, this
is intentional and will break source compatibility. Simply replacing
an index() call with the equivalent strchr() should be enough to fix
this in third-party code.
- Remove bionic/index.cpp from the tree and build files.
- Remove x86 assembly implementation from arch-x86/ to avoid conflict
with the one in ndk_cruft.cpp

getdtablesize(3) was removed fro POSIX 2004. Keep the symbol around in LP32 for
binary compatibility, but remove the declaration from unistd.h.

This is the change to export the tty ldisc definitions (like N_TTY)
from Linux uapi kernel header. So bionic is compatbile with glibc
which has its own tty ldisc definition exported through ioctl.h

Add 64-bit bionic implementation for denver. memcpy/memset are
denver-specific optimized. Use generic version of other routines.
