Some gloox headers need workarounds to be included, so mark the header
"lib/external_libraries/gloox.h" as source for all gloox symbols and
collect all headers we use under it.
Further make include-what-you-use happy with files in source/lobby and
fix what needs to be fixed after.

This wrapper was meant to support multiple C++ ABIs with a single
pre-built gloox library wrap as a C library. A new ABI change was
rejected a few years back, so this will probably take a while for it to
be on the table again. With the bug tracker and mailing list currently
unavailable and known TLS issues we might have replaced gloox by then
anyway.
Supporting multiple ABIs with the current setup isn't an issue either
and is already done for 32bit vs 64bit ABI on Windows.
Therefore use gloox types directly in lobby code instead of wrapper
types and delete the wrapper and build-integration.
Migrate to override where applicable, as it helped avoid subtle
differences in signatures and finding missing inheritance of LogHandler.
Finally use version check instead of os check to work around Windows
using the 1.1 development branch instead of releases.
