This is a massive win on OSX, which doesn't have a sha256sum normally.
Only use external hash commands when the file is > 1 mb,
since cryptohash is quite close to them in speed.
SHA is still used to calculate HMACs. I don't quite understand
cryptohash's API for those.
Used the following benchmark to arrive at the 1 mb number.
1 mb file:
benchmarking sha256/internal
mean: 13.86696 ms, lb 13.83010 ms, ub 13.93453 ms, ci 0.950
std dev: 249.3235 us, lb 162.0448 us, ub 458.1744 us, ci 0.950
found 5 outliers among 100 samples (5.0%)
4 (4.0%) high mild
1 (1.0%) high severe
variance introduced by outliers: 10.415%
variance is moderately inflated by outliers
benchmarking sha256/external
mean: 14.20670 ms, lb 14.17237 ms, ub 14.27004 ms, ci 0.950
std dev: 230.5448 us, lb 150.7310 us, ub 427.6068 us, ci 0.950
found 3 outliers among 100 samples (3.0%)
2 (2.0%) high mild
1 (1.0%) high severe
2 mb file:
benchmarking sha256/internal
mean: 26.44270 ms, lb 26.23701 ms, ub 26.63414 ms, ci 0.950
std dev: 1.012303 ms, lb 925.8921 us, ub 1.122267 ms, ci 0.950
variance introduced by outliers: 35.540%

mean: 26.84521 ms, lb 26.77644 ms, ub 26.91433 ms, ci 0.950

For an unknown reason, getAddrInfo currently is segfaulting. Note that
in February, I had used warpDebug, which uses getAddrInfo, and it worked.
Don't know if my toolchain has changed and broke it, or it's due to having
a different Android device now. Anyway, work around it by hardcoding the
address to use.

This caused the code to fail on Android, which doesn't know that flag.
It seems best to let the OS default flags be used. Tested working ok on
Linux. The only difference on Linux is it might return a v4mapped ipv6
address sometimes.

I've found multiple references to using the `am` command from the adb shell
to open a browser. So I assume it also works in a terminal emulator.

connecting to it from another.
Does not yet use HTTPS. I'd need to generate a certificate, and I'm not
sure what's the best way to do that.

avoids a warning, which says it's faster

caused regular browsers to stall when they reuse a connection after leaving it idle for 30 seconds. (See https://github.com/yesodweb/wai/issues/146)

It used to not log to daemon.log when a repository was first created, and
when starting the webapp. Now both do. Redirecting stdout and stderr to the
log is tricky when starting the webapp, because the web browser may want to
communicate with the user. (Either a console web browser, or web.browser = echo)
This is handled by restoring the original fds when running the browser.

since some systems may have configuration problems or other issues that
prevent web browsers from connecting to the right localhost IP for the
webapp.
Tested on both ipv4 and ipv6 localhost. Url for the latter looks like:
http://[::1]:50676

Browser behavior is not ideal; a new tab is opened on restart.
Browsers won't let me redirect to a file:// so I cannot use the old tab.

Should fix a crash reported on OSX.

This is a workaround for bind failing with EINVAL sometimes on OSX.
I don't know why; EVINAL should mean the socket is already bound to an
address, but this is with a new socket.

The webapp can only run on one of ipv4 and ipv6, no both. Some web browsers
may not support ipv6, so ipv4 is the safe choice.
The actual problem I ran into with it only listening to ipv6 was that
Utility.Url.exists was failing to connect to it. I doubt that haskell's
HTTP library is ipv4 only. More likely, it was only trying one address,
and tried ipv4 first.

To avoid conflict with different liftIO from MonadIO (in some version of
yesod not the one I have here), and because it's generally clearer, since
this module has both Wai and Yesod stuff, to qualify them both.

Old 1.0.1 version is still supported as well. Cabal autodetects
which version is available, but in the Makefile, WITH_OLD_YESOD
has to be configured appropriately.
I have not squashed all the $newline warnings with the new Yesod.
They should go away eventually anyway as Yesod moves past that transition.

This avoids forking another process, avoids polling, fixes a race,
and avoids a rare forkProcess thread hang that I saw once time
when starting the webapp.

Not needed, and causes a segfault on OSX when it tries to dereference the
NULL servicename. (Linux handles this case better.)

Useful for testing..
