Remove mspace functionality from cutils.
Directly declare mspace from dlmalloc in code flinger's code cache, and
manage without using morecore.

Provides a new mechanism for dumpstate (while running as root)
to request that debuggerd dump the stacks of native processes that
we care about in bug reports. In this mode, the backtrace
is formatted to look similar to a Dalvik backtrace.
Moved the tombstone generating code into a separate file to
make it easier to maintain.
Fixed a bug where sometimes the stack traces would be incomplete
because we were not waiting for each thread to stop after issuing
PTRACE_ATTACH, only the main thread. So sometimes we were missing
traces for some threads.
Refactored the logging code to prevent accidentally writing data
to logcat when explicitly dumping a tombstone or backtrace from the
console.
Only root or system server can request to dump backtraces but
only root can dump tombstones.

qsort_r() is declared differently on BSD and GNU libc and
may be absent on other platforms.
Provide qsort_r_compat() which should work everywhere.

Both libraries are needed to build four shared libraries in 64-bit

The strftime_tz() function is not a standard C library function and should not
appear in <time.h>. Instead, it is being moved to <bionic_time.h>, a private
header only available to platform libraries.

This adds a new function to libcutils, partition_wiped().
This is used to determine if a partition is wiped.

Ext4 filesystems like to be unmounted before rebooting. The Android system
doesn't have a traditional Linux init setup, and shutting down the system
was not much more than calling sync(2) and reboot(2). This adds a new
function to libcutils called android_reboot(). By default, it calls sync()
and then remounts all writable filesystems as read-only and marks them clean.
There is a flag parameter in which the caller can ask for sync() not to be
called, or to not remount the filesystems as read-only. Then it will call
reboot(2) as directed by the other parameters. This change also updates
adb, init and toolbox to call the new android_reboot() function.
Fixes bugs 3350709 and 3495575.

This change moves the ARM definitions into GCC extended inline
assembler. In addition, the same set of x86 definitions are now
shared among all x86 targets.

Added atomic-inline.h. Added a platform-specific memory barrier call
there.
Added android_atomic_acquire_cmpxchg() and android_atomic_release_store().
Not tested on Mac OS X or SH.
Added memory barrier calls to linux-x86 atomics. Mac OS X has barrier
functions already. sh isn't really SMP-ready. linux-arm needs work
(to be done in a separate change).
Updated the makefile to make the SMP state visible to the code here.
Note that host binaries are NOT built with SMP enabled; while our hosts
are very likely SMP, it's not worth figuring out e.g. whether it's okay
to use the SSE2 mfence instruction or have to use something else. We
haven't had barriers enabled in host tools before, so there's probably
no need to stat now.
Removed quasiatomic 64-bit calls (now part of Dalvik).

POSIX seems to have chosen open_memstream() over the BSD variant. We
want something for Dalvik that will work on both GNU/Linux and Android,
so this is open_memstream() implemented in terms of BSD funopen().
For Windows there's just a stub that calls abort().
I'm putting this in libcutils since it seems inappropriate for bionic
(which provides the BSD alternatives) but isn't Dalvik-specific.

asocket_connect()
asocket_accept()
asocket_read()
asocket_write()
These calls are similar to the regular syscalls, but can be aborted with:
asocket_abort()
Calling close() on a regular POSIX socket does not abort blocked syscalls on
that socket in other threads.
After calling asocket_abort() the socket cannot be reused.
Call asocket_destory() *after* all threads have finished with the socket to
finish closing the socket and free the asocket structure.
The helper is implemented by setting the socket non-blocking to initiate
syscalls connect(), accept(), read(), write(), then using a blocking poll()
on both the primary socket and a local pipe. This makes the poll() abortable
by writing a byte to the local pipe in asocket_abort().
asocket_create() sets the fd to non-blocking mode. It must not be changed to
blocking mode.
Using asocket will triple the number of file descriptors required per
socket, due to the local pipe. It may be possible to use a global pipe per
process rather than per socket, but we have not been able to come up with a
race-free implementation yet.
All functions except asocket_init() and asocket_destroy() are thread safe.

Move fdevent from libcutils into adb directory. ADB is the only client of this API, and I intend to modify it extensively to clean its codebase soon.
