Fix connect(2) callers to use correct sockaddr size.

Some systems (eg Mac OSX 10.5) require the length passed to match
the socket address family. This introduces sys_connect() that does
the right thing, and replaces all uses oc connect(2) with sys_connect().

Note that there are some LGPL callers that still call connect(2)
directly.
(This used to be commit e1bfdc17c49da582cdf907e260301ab1946b2ed3)
