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
the old C++ API.

This change adds a layer of indirection to uevent's
uevent_kernel_multicast_recv, allowing dependent code to
get the remote endpoint if desired.

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);

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.

This will make it easier to add additional policies (cgroups) if needed.
Also added comments to the sched_policy APIs.

1. In printf, use "%zu" for variable of type size_t
2. Print tid in %5d
3. Make type of pid/tid in AndroidLogEntry and logger_entry consistent

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.

* Add support for
deleteTagData(tag, uid)
setCounterSet(counterSetNum, uid)
setPacifier(on)
* Add resource tracking
(If only kernel process termination had a hook)
Because the xt_qtaguid netfilter module needs to keep track of
tagged sockets, it needs a way to know when the process owning
the socket has died.
Normally the app will untag the sockets. But not on crash.
So the process opens the qtaguid misc dev, which is closed on crash,
at which point the xt_qtaguid can force-untag the processes sockets,
and thus allowing their refcount to go down and release them.
* Add pacifier support
Add function to enable/disable pacification of the xt_qtaguid
kernel module. (mostly for debugging)
