Current default is 256kbps, which produces inconsistent
results (too high for low-res, too low for hi-res).
Use CRF instead, which will adapt.

The following are the newly added options:
arnr_max_frames, arnr_strength, aq_mode, denoise_noise_level, denoise_block_size,
rc_undershoot_pct, rc_overshoot_pct, minsection_pct, maxsection_pct, frame_parallel,
enable_cdef, enable_global_motion, and intrabc.
Also added macros for compiling for aom 1.0.0 and fixed the default values.

fixed the error in Intel(R) Xeon(R) Gold 6152 CPU like:

Adds an option to specify the number of tile rows and columns, then uses
a uniform tiling if possible and otherwise a fixed tiling with equal-sized
tiles to fill the frame.
Also adds -tile-columns and -tile-rows options to make tilings with
power-of-two numbers of tiles, matching the behaviour of the libvpx/VP9
encoder.
The libaom doxy says that a value of 0 for the threads fields is
equivalent to a value of 1, whereas for avctx->thread_count it means
the maximum amount of threads possible for the host system.
Use av_cpu_count() to get the correct thread count when auto threads
is requested.

aom_codec_get_global_headers() is not implemented as of libaom 1.0.0 for AV1, so
we're forced to extract the relevant header OBUs from the first packet and propagate
them as packet side data.

* commit '43778a501f1bfbceeddc8eaeea2ea2b3506beeda':
Support AV1 encoding using libaom
This contains some extra changes taken from the libvpx encoder
wrapper, most of them contained in the set_pix_fmt() function.
