Test av_get_pix_fmt / av_get_pix_fmt_name round-trip across all
pixel formats, av_color_{range,primaries,transfer,space}_name,
av_chroma_location_name and av_alpha_mode_name round-trips
through their from_name() counterparts using a name-equivalence
check (two enum values may legitimately share the same name
string), av_chroma_location_enum_to_pos and pos_to_enum
round-trip across all valid chroma locations, and iterate every
pixel format printing av_get_padded_bits_per_pixel and
av_pix_fmt_count_planes.
Coverage for libavutil/pixdesc.c: 83.63% -> 90.03%
Numbers measured against a full FATE run. Remaining uncovered
lines are av_get_pix_fmt_string, the av_get_pix_fmt_loss /
av_find_best_pix_fmt_of_2 public wrappers and a few loss
branches, the palette branches of av_read_image_line and
av_write_image_line, and the *_ext name lookups in
av_color_{primaries,transfer}_from_name.
