[crossfire] Crossfire server code cleanup/janitorial

[Mark Wedel]

  Just a quick note:

While using external libraries for certain common things can be handy, one also 
has to be careful about how common these libraries are (eg, if it doesn't exist 
on certain platforms, its convenience factor goes down a whole bunch)

Beyond that, there was a separate ticket/discussion about the need to have perl 
for the server on windows to collect the archetypes.  To me, that isn't a big 
issue, but so some it is, and if that is an issue, I'd then think requiring 
additional libraries would fall into that extra pain.  It could also make binary 
distributions harder

certainly, using standard functions that are available on all systems and 
simplify life should be done.

  The socket code got a bit messy with all the WIN32 #ifdefs - a simpler 
solution there would probably be add a 'read_from_socket' type function which 
makes the appropriate call and checks the appropriate error types and returns 
appropriate error code, so all that logic only has to be in one function and not 
duplicated many times.  Same could be done for the write calls.
