Update wx/android/setup.h automatically from wx/setup_inc.h too.

Not sure if this file is actually used at all right now, but update it to
avoid discrepancies with the other setup[0].h.

Add default argument for the overridden base class Connect() in wxHTTP.

This allows to call Connect(wxIPV4address) on a wxHTTP object, without
having to explicitly specify the second argument (this was documented as being
a Watcom-specific problem, but actually it wasn't).

Remove (Open)Watcom support.

This compiler is not being developed since several years and almost certainly
can't be used to build the current wxWidgets sources anyhow, so remove all
support for it, including a lot of extremely ugly workarounds for its bugs
with template functions.
