New decoder control paramter VP8_SET_DECRYPT_KEY to set the decryption key.

Change-Id: I6fc1f44d41f74f3b3f702778af1a6f8f5cc9439f

Writing all #define guards using the same style. Inlining macro
VP8DX_BOOL_DECODER_FILL into vp8dx_bool_decoder_fill. Removing unnecessary
includes.

Adds an option, --scale, that will rescale any frames produced by
the decoder that don't match the resolution of the first frame to
that resolution. This is useful for playback of files that use
spatial resampling.

Fixes a rollover of the cx_time variable for encodes that take
over ~4200 seconds. Also enable the time estimate in first pass.

Scales the input of the encoder using libyuv's "box filter". Each stream
may have a different width and height specified. If the width (or
height) parameter is missing (or is explicitly set to 0) then the value
will be calculated based on the specified height (or width) and the
input file's dimensions, preserving its aspect ratio. Leaving the height
unspecified behaves similarly.

Allows the user to specify whether decode errors should be fatal or not.
Also makes mismatches optionally fatal.

Make the progress line more useful by providing per-frame updates of
processing frame rate and estimated time remaining.

Fixes issue #534.

Remove dependency of this function on asm_offsets. ssse3/sse4 next.

Change quant_shift calculation so it be done using SIMD. Pre-calculate
as much as possible to simplify EOB selection.

Take advantage of qcoeff being zero'd by tying the if statements
together.

Reduce dependency on offsets file by using intrinsics. Disassembly shows
improvements over previous assembly specifically in register management,
preloading, and {pro,epi}log. Speed change is within margin of error.

Change-Id: I36f4ba5700f6f4615057daf7e70868f68a86669f

The issue that potentially broke the encoding process was due to the fact
that the length of token link is calculated from the total number of tokens
coded, while it is possible, in high bit-rate setting, this length is
greater than the buffer length initially assigned to the cpi->tok.

This patch increases the initially allocated buffer length assigned to
cpi->tok from
(mb_rows * mb_cols * 24 * 16) to (mb_rows * mb_cols * (1 + 24 * 16)).

It resolves the buffer overflow problem.
