2643dd0ea5 test.bash: don't let the test process inherit the lock file 
This meant that dangling mounts (and gocryptfs processes) kept
the lock open.

94b66ee1b2 tests: only check the size in dl-linux-tarball.bash 
Getting rid of the MD5 calculation makes calling the script
virtually free, where it took 0.2 seconds before.

12374be9c5 ctlsock: abort the connection if the request is too big 
Reading partial JSON would cause a mess. Just kill the connection.

Also, stop using syscall.PathMax that is not defined on Darwin

7fc93ec093 main: fix USR1 race condition, fixes test flakiness 
We could have gotten the signal before the handler was ready,
which caused the process to wait indefinitely. This was the reason
test.bash sometimes hung.

10884603d8 benchmark.bash: double write length 
Writing 1000 128KB blocks takes only 1 second and yielded
inconsistent results. With 2000, things look saner.

0f8d3318a3 main, fusefrontend: add "-noprealloc" option 
Preallocation is very slow on hdds that run btrfs. Give the
user the option to disable it. This greatly speeds up small file
operations but reduces the robustness against out-of-space errors.

Also add the option to the man page.

024511d9c7 fusefrontend: coalesce 4kB writes 
This improves performance on hdds running ext4, and improves
streaming write performance on hdds running btrfs. Tar extract
slows down on btrfs for some reason.

d3764b7753 reverse: fix longname decoding bug 
This could have caused spurious ENOENT errors.

That it did not cause these errors all the time is interesting
and probably because an earlier readdir would place the entry
in the cache. This masks the bug.
