Instead of using a directory, hash the timestamps into the cache keys
themselves. Since there is no more timestamp directory, there is no more
need for deleting the cache of other mesa versions and we rely on
eviction to clean up the old cache entries. This solves the problem of
using several incarnations of disk_cache at the same time, where one
deletes a directory belonging to the other, like when both OpenGL and
gallium nine are used simultaneously (or several different mesa
installations).

cache_put() first creates a .tmp file and then tries to do eviction.
The recently added LRU eviction code selects non-empty directory with
the oldest access time, but that may easily be the one with just the
new .tmp file, especially on Linux where atime is updated lazily
(with "relatime" mount option, which is the default). So when cache is
small, if random doesn't hit another dir LRU keeps selecting the same
dir with just the .tmp and not deleting anything. To fix this (and the
tests), do eviction earlier.

This reduces the cache size for Deus Ex from ~160M to ~30M for

I'm also seeing the following improvements in minimum fps in the

no-cache: ~10fps
with-cache-no-compression: ~15fps
with-cache-and-compression: ~20fps
Note: The with cache results are from the second run after closing
and opening the game to avoid the in-memory cache.
Since we mainly care about decompression I went with
Z_BEST_COMPRESSION as suggested on irc by Steinar H. Gunderson
who has benchmarked decompression speeds.
Grigori Goronzy provided the following stats for Deus Ex: Mankind
Divided start-up times on a Athlon X4 860k with a SSD:
No Cache 215 sec
Cold Cache zlib BEST_COMPRESSION 285 sec
Warm Cache zlib BEST_COMPRESSION 33 sec
Cold Cache zlib BEST_SPEED 264 sec
Warm Cache zlib BEST_SPEED 33 sec
Cold Cache no compression 266 sec
Warm Cache no compression 34 sec
The total cache size for that game is 48 MiB with BEST_COMPRESSION,
56 MiB with BEST_SPEED and 170 MiB with no compression.
These numbers suggest that it may be ok to go with Z_BEST_SPEED
but we should gather some actual decompression times before doing
so. Other options might be to do the compression in a separate
thread, this might allow us to use a higher compression algorithim
such as LZMA.
