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.

This is more stylistic than substantial, but it's bad enough
style to be worth fixing.

We were potentially passing (char *)NULL to string constructors.

I think this one was actually impossible to trigger.

Resolves #719.

For example, do not interpret regex metacharacters within the
hostname, and avoid accidentally matching the username part of
username@hostname when they happen to match.

Improves 679b8192 to make it simpler to
ignore mosh-client from OS X Terminal.app's "Ask before closing" process
list. (See: http://superuser.com/a/254647)

Moreover, the command displayed from ps is a completely functional one,
which was not the case in the previous approach, that mangles `argv[0]`.

Fixes #742.

Motivated by Cygwin.
