This change adds support for tracing using the ATRACE_TAG_APP tag. This tag is
enabled only for processes in which the /proc/<pid>/cmdline value appears in
the comma-separated list of such values in the debug.atrace.app_cmdlines system
property. It is also only enabled if either the ro.debuggable system property
is set to 1 or the application has declared itself debuggable in its manifest,
which gets reported to libcutils by the framework.

We assume ARMv7 which with thumb2 has ldrex/strex operations that may be
inlined if -mthumb is defined.
Remove remnants of ARMv5 support.

Don't depend on sys/cdefs.h, which doesn't exist when building

in mingw32, it doesn't work.

Try to verify, at compile time, that the supplied
value buffer is large enough.
There's more we can do here, but this is a good first
pass.

The various atomic operations are declared as inline in the header files
to cut the function call overhead. However, the plain inline keyword is
just a suggestion to the compiler which makes its own decision on whether
to inline them or not. Worst, if they are not inlined, the
-fvisibility-inlines-hidden compiler flag will render them as hidden
symbols in the object file. If they are picked up by the linker over the
ones supplied in libcutils.so the following warning will be reported:
warning: hidden symbol 'android_atomic_inc' in foo.o is referenced by
DSO bar.so
One way is to add __attribute__((visibility("default"))) to those inline
functions to suppress the linker warnings. A better way is to force
inlining as with this patch.

With inline atomics, trace functions have no non-inline function calls
in the fast (tracing off) path. To enable this, ANDROID_SMP must be
defined for the project. Otherwise, normal (non-inline) atomics are
used.

Basic tracing functionality to cutils, which can be turned on at start,
or dynamically controlled by the frameworks. The goal is for hardware
modules to add tracing that will be controlled by their respective
services.

This will eventually allow us to remove the code in
logd_write.c#__android_log_write which uses the tag
to direct logs to the radio buffer.

Remount rootfs as recursively shared, so that mount changes are
propagated into child namespaces. Mount external storage for access
from adb.
Clean multi-user dependencies for use in Dalvik. Also define

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.

Also tid == 0 maps to gettid() on platforms that support it.
This is needed by mediaserver code that was formerly using

Android's kernel logger can optionally return UID information
in addition to the previously returned information. This
information is available by telling the kernel to use the
updated structure via the newly introduced LOGGER_SET_VERSION
ioctl.
int fd = open("/dev/log/main", O_RDONLY);
int version = 2;
ioctl(fd, LOGGER_SET_VERSION, &version);
