Jay Conrod 0e21d5be37 [dev.fuzz] internal/fuzz: read and write interesting values in fuzz cache 
'go test -fuzz' may now read and write interesting fuzzing values to
directories in $GOCACHE/fuzz. Files in this directory are named
$pkg/$test/$hash where $pkg is the package path containing the fuzz
target, $test is the target name, and $hash is the SHA-256 sum of the
data in the file.

Note that different versions of the same package or packages with the
same path from different modules may share the same directory.

Although files are written into a subdirectory of GOCACHE, they are
not removed automatically, nor are they removed by 'go clean -cache'.
Instead, they may be removed with 'go clean -fuzzcache'. We chose to
nest the fuzzing directory inside GOCACHE to avoid introducing a new
environment variable, since there's no real need for users to specify
a separate directory.
