clawbot 83087db6a0 Serve a cache hit with no database read or write (closes #309) ...

A hit opens the variant file and nothing else: its content type comes
from the file's first bytes, and a file in no output format is a miss
and is made again. Its access time and hit count are handed, without
waiting, to the goroutine that wrote late counts, which now writes every
count and the access times once a second; the access times wait in a
channel of 10,000 that drops the rest. checkNegativeCache leaves expired
rows to CleanExpired. The .meta files, metaCache, Lookup and golang-lru
go, with their tests; tests that read counts after Get wait for the
background write. make bench runs a parallel cache hit benchmark,
outside make check.
