msm: kgsl: add userspace memory alloc and free tracepoints

Add events for tracking memory operations by userspace
clients: kgsl_mem_alloc, kgsl_mem_map, kgsl_mem_free,
kgsl_mem_timestamp_queue (adding an entry to the free
on timestamp list) and kgsl_mem_timestamp_free (when
the memory is actually freed).

msm: kgsl: fix statistics for ion memory regions

The sysfs code was reading the wrong entry in the stats

msm: vidc: Reset stop_called state when START is called

The driver needs to reset the stop_called field once START called.
Otherwise in START, STOP, START, STOP sequences the secondary STOP
will be treated as a duplicate STOP and ignored.

msm: vidc: set EOS on output buffer pending transaction

If EOS is signalled while an output buffer is in transaction,
mark EOS when that buffer is returned.
This is observed in case client sends an empty buffer with EOS.

vidc: Fix EOS handling if video h/w has a frame in transaction

In case of video hardware is encoding a frame and EOS buffer with
with zero data length arrived, set the EOS flag to the transaction
available in the transaction table which will be passed to the
client in frame done callback from the video hardware.

msm: vidc: add support for the bitstream_restrict flag

Adds support for the MFC core to add the bitstream_restrict flag in the
sps/pps for H264 codecs.  This allows for the decoder to determine how
many frames to buffer when decoding.

msm: kgsl: Properly record the size of the sglist in the memdesc

It was possible to fail out of kgsl_sharedmem_alloc after a sglist was
allocated but before we saved the size of the allocation which caused
problems when the sglist was freed during cleanup.

msm: kgsl: Move events to context specific lists

Move the event accounting from a master list on the device to individual
context lists. This makes the management code more simple and reduces
the amount of extra cycles taken trying to walk a single largish list.
The new added code makes the event code slightly bigger than kgsl.c can
bear. As events become more commonplace this code will be more important
and it will be easier to maintain in a dedicated file so move all the event
related code into kgsl_events.c

msm: kgsl: Send the correct timestamp to an expired event

Instead of sending the currently expired timestamp to expired
events, send the timestamp that the event expected. This avoids
confusion for events that don't compare the actual timestamp
to the one they expected.  Canceled events send the current
timestamp when they were canceled.

The kgsl_sync handler wasn't prepared for the second case so
add a check to prevent strange things from happening on the
timeline when a event is canceled.

msm: kgsl: Use the correct timestamp for the snapshot

The snapshot timestamp is currently based on wall time which makes
it very difficult to debug against a kernel log based on boot time.
It doesn't help matters that the snapshot timestamp is output in
human unfriendly hex.  Use boot time instead of wall time for the
snapshot value and print it out in decimal.
