Resolves #786.

Replace some blind timeouts with actual synchronization.
Improve performance on some slow tests.
Tweak some of the remaining timeouts.

This still isn't good enough to get 'make -j9 check'
working reliably on Cygwin for me; I think some Cygwin/
Windows scheduling issues remain.

See https://github.com/tmux/tmux/issues/539

This also serves nicely as documentation of the Cygwin build
requirements.

Discovered with OpenBSD 6.0 /bin/sh

Fixes #788.

This also works around issues with remote pty typeahead echo corrupting output
from mosh-server.

This eliminates issues with typeahead being echoed by the remote pty
and corrupting remote output from mosh-server to the mosh script, but
cannot be made default because older mosh-servers require a pty.

It looks like Mosh used to be able to do this but the capability was
lost when port ranges were added in 141ec239.

Also cleans up other setsockopt() calls, and buffer sizing/handling
for recvmsg().

These are minor errors and no actual misbehavior was observed.
Discovered while working Windows Subsystem for Linux compatibility
issues.

This moves all routine stdout/stderr output into the parent
server, and adds tcdrain(), even though this may be a
FreeBSD pty bug.

This is an old, old bug.

If #mosh ever sets the +n channel mode, we'll need to remove the
`skip_join: true` part

It may contain configuration that breaks our testing.

Seems to fix #773.

Resolves #764, mostly.

OS X advertises IPv6 link-local addresses for .local hostnames.
getaddrinfo() correctly reports interface identifiers for these, but we
were discarding them by using the socket peer host address instead.

Rather than trying to validate, accept any option to the bind-server
option, and allow mosh-server to validate it, as noted by
https://github.com/mobile-shell/mosh/pull/670#issuecomment-135147605

Fixes a Lintian warning.

Also require Perl 5.14, which is the new compatibility
floor.

Fixes #758.
