The previous change to disable some vsx functions did not clear
the test failures. Disable vsx by default until it is investigated
and fixed.

- Save the initial user-specified timestamp and rebase all further
timestamps by this value. This makes libvpx internal timestamps to
always start from zero, regardless of the user's timestamps.
- Calculate reduced timestamp conversion ratio and use it to convert
user's timestamps to libvpx internal timestamps and back. The effect
of this is that integer overflow due to multiplication doesn't
happen for a much longer time.

Change-Id: Ic6f5eacd9a7c21b95707d31ee2da77dc8ac7dccf
fmemopen is not preferred during fuzzing.
Removed all file operations.
Removed need for allocating a different input buffer.
data buffer is appropriately incremented and passed directly to decoder
This will also test input being sent in an unaligned buffer to the library.
Removed read_frame function and did the required parsing inline.

This patch uses ARF itself as the GOLDEN frame for the
next gf group instead of replacing it with the overlay
frame. By doing so, bits consumed by the overlay frame
will be reduced.

This CL fixed a bug that sometimes we calculate the best rd cost using
uninitialized rd_div. This CL also includes a small refactoring of
rd_pick_partition().

Test was running at speed 4, which is not used for real-time.
With this change all Datarate tests are now running at
(speed >= 5, 1 pass, real-time mode), which is what they
were intended for.

Use different lagrangian multiplier scaling factor for different block
size. The blocks whose sizes are less than 16x16 share the same multiplier
of their parent block.

* changes:
Update rdcost using the rd_mult in current block
Use distortion and rate of best_rd as the params
Use distortion and rate recursively in rd_pick_partition()
