Previously, if the wall0 test failed, the short-circuit effect of
boolean AND allowed the code to skip initializing wall1, even when cside
and its wall_num should have caused wall1 to be non-NULL. Swap the
order of the tests so that the short-circuit only skips statements that
have no side effects.

Jayman2000 reports that users who do not update their MED.MNU after
updating to 8b61b9f ("Remove unused symbols") receive an "editor crash"
on startup. This is not a crash, but instead is poor error handling in
menubar.cpp, which calls UserError instead of ignoring the offending
line. Calls to UserError are fatal, but do not crash the program.
Replace that call with a con_printf(CON_URGENT) and ignore the line.
Additionally, change the handling for excess menus and for excess menu
items to con_printf+ignore instead of UserError.

BM_XRGB doubles its inputs. 35a4736 doubled the inputs explicitly, but
passed them back to BM_XRGB, which doubled them again. Switch to a
direct call to gr_find_closest_color to skip the second double pass.

gameseq_init_network_players updates the Players array after loading a
level. This should always be done, since players may change their
object number across levels. Move the call into LoadLevel since some
callers failed to do it.
Windows 2000 has no support for getaddrinfo. Five years ago (Apr 5
2011), the addition of tracker support
(7f18afd5d7) brought a requirement for
getaddrinfo. Recently, someone with a working Windows 2000 system
reported that Rebirth no longer starts on Windows 2000. Although such
systems should not be connected to the Internet, they may still need
name resolution on a LAN. Add a configure test to probe for getaddrinfo
support and fall back to gethostbyname if needed.
Compiling a binary that works on Windows 2000 requires one of:
* using an ancient SDK that does not declare getaddrinfo
* defining _WIN32_WINNT to exclude Windows XP support
* overriding the SConf test to force failure
Fixes: 7f18afd5d7 ("Client-side implementation for Tracker support by Matt 1360 Vandermeulen including improvements in udp_dns_filladdr and IPv4/IPv6 compability; Very little adjustments by me, too including IPv6 support for Windows (untested); Actual tracker code will follow later as seperate branch when it's done")
