Import r67258 of the wxWidgets trunk, which I expect will before

Browse Source 
long become wxWidgets 2.9.2, which in turn is expected to be the
last 2.9 release before the 3.0 stable release.

Since the full wxWidgets distribution is rather large, I have
imported only the parts that we use, on a subdirectory basis:

// sockets. It can be initialized from an existing sockaddr struct and also
// provides access to sockaddr stored internally so that it can be easily used
// with e.g. connect(2).

// This class also performs (synchronous, hence potentially long) name lookups
// if necessary, i.e. if the host name strings don't contain addresses in
// numerical form (quad dotted for IPv4 or standard hexadecimal for IPv6).
// Notice that internally the potentially Unicode host names are encoded as
// UTF-8 before being passed to the lookup function but the host names should
// really be ASCII anyhow.
