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.

Should resolve https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=811579

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.

Fixes #745.

There are (broken) compilers out there that accept -fstack-protector-*
parameters, but do not provide the needed ssp library. As a result,
build does not fail, but link does. Use the local check_link_flag
autoconf function to correctly test for SSP availability.

Required for the Imagination Technologies Codescape IMG MIPS
toolchain, version 2015.10 (and who knows what else).

Fixes #744.

This should resolve mobile-shell/mosh#675
