Subject: Further improve try_bind().
X-Git-Url: http://git.meshlink.io/?a=commitdiff_plain;h=1ab9403c5eb08bcb47e8e1599764b5465c79795b;hp=1ab9403c5eb08bcb47e8e1599764b5465c79795b;p=meshlink

Further improve try_bind().

Make try_bind() do the same checks as add_listen_address() does: try to
create both a TCP and UDP socket on a given port for all address
families. If one address family succeeds for both TCP and UDP, consider
this a valid port.
