cpp (chars-per-pixel) is an integer that fails to give useful data
about most compressed formats. Instead, rename it to "bs" which
stands for block size (in bytes).
v2: Rename vk_format_for_bs to vk_format_for_size (Chad)
Use "block size" instead of "bs" in error message (Chad)

Version 0.170.2 removes most of the error enums. In many cases, I had to
replace an error with a less accurate (or even incorrect) one.
In other cases, the error path is replaced with an assertion.
Previously, there were a number of things we were doing wrong:
1) We weren't flushing the wl_display so dead-looping clients weren't
guaranteed to work.
2) We were sending the frame event after calling wl_surface.commit() so it
wasn't getting assigned to the correct frame
3) We weren't actually setting fifo_ready to false.
Unfortunately, we never noticed because (3) was hiding the other two. This
commit fixes all three and clients that use FIFO mode are now properly
refresh-rate limited.
