mm-video-v4l2: vdec: Avoid processing ETBs/FTBs in invalid states
(per the spec) ETB/FTB should not be handled in states other than
Executing, Paused and Idle. This avoids accessing invalid buffers.
Also add a lock to protect the private-buffers from being deleted
while accessing from another thread.

mm-video-v4l2: vidc: fix matching of extension strings
Using strncmp with the strlen of source string can result in
false positives when it is a substring of the passed string.
Eg: strncmp("OMX.extn.x", "OMX.extn.xyz", strlen(OMX.extn.x))
will result in a match.
Use strcmp instead.

mm-video-v4l2: vdec: deprecate unused config OMX_IndexVendorVideoExtraData
This config (used to set header offline) is no longer used.
Remove handling this config since it uses non-process-safe ways to
pass memory pointers.

mm-video-v4l2: vdec: add safety checks for freeing buffers
Allow only up to 64 buffers on input/output port (since the
allocation bitmap is only 64-wide).
Do not allow changing the actual buffer count while still
holding allocation (Client can technically negotiate buffer
count on a free/disabled port)
Add safety checks to free only as many buffers were allocated.
Fixes: Security Vulnerability - Heap Overflow and Possible
Local Privilege Escalation in MediaServer (libOmxVdec problem #3)

mm-video-v4l2: vdec: Add range check before native_buffer usage
Restore missing buffer-index calculation, without which,
native-handles were not being saved properly and NULL handles
got sent out to gralloc::setMetadata
A bad buffer index can cause the OMX component to make an out of
bound read/write access on the native_buffer array and cause a
crash. Add range check to fix the issue.
