This change adds init.rc steps to:
* allow kernel tracing to be enabled via adb
* allow a limited set of kernel trace events to be enabled via adb
* allow the kernel trace to be read via adb
* allow all users to write to the kernel trace from userland

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.

With this change, the audio rr/fifo threads will just run in
the fg cgroup.
Also, the RR budget for the apps fg/bg threads has been bumped
to 80%. Ideally, the bg budget would be much smaller but there
are legacy libraries that seem to be very sensitive to this so
for now keep it at this value.

p2p interfaces keep increasing. Reuse a single "p2p" phrase to track all
p2p specific properties.
Longer term, we will remove the use of system properties for dhcp
Also, fixed some warnings

GPS on yakju puts SCHED_RR threads in the fg and bg groups, and

If the bootloader doesn't support formatting of those partitions
(either because it doesn't support the getvar commands needed or
the partition type is not supported), the errors are printed but
doesn't halt processing of subsequent commands.

It's safe to change the permissions on files in the root partitions;
incremental OTA now knows how to handle this case.

This change replaces the set_active_rect function with set_post_transform_crop.
There is a temporary set_active_rect function that calls
set_post_transform_crop for compatibility while commiting to multiple git
repositories.

mkbootfs uses the compiled in fs_config() function to set the mode
(but not the uid or gid) of the files in the filesystem it is
building. Give it an optional "-f filename" flag to allow loading the
list of file permissions from a file, so we can continue to accurately
recreate old filesystems even when the current fs_config() has changed.

Slightly optimizes the writes used by sdcard to increase
throughput and decrease cpu load. Update the read
size to 256 x 1024 + 128 from current 8192 bytes since
writes can go as high as that.

The new fs_mgr library moves much of the knowledge of what filesystems
to mount into a new fstab.<device> file, and just calls one function to
mount all the filesystems.

Instead of specifying in init what to mount, and having various hacks in init
itself to deal with encryption, use a filesystem manager library to do the
work, that can also be invoked by vold when mounting an encrypted volume.
Keep all the magic filesystem info an a device specific fstab file.
