Allow use of []-wrapped addresses in git://

Allow using "["<host>"]":<port> and "["<host>"]" notations in git://
host addresses. This is needed to be able to connect to addresses
that contain ':' (e.g. numeric IPv6 addresses). Also send the host
header []-wrapped so it can actually be parsed by remote end.
