that's useful to the client or the players. This should solve the problem
with QW clients' tiny setinfo buffers once and for all. Note, you can
still use setinfo to set your user info, but if it's not in the
"need-to-know" list, the server won't send it back to you. I will probably
make this optional with a server Cvar if there are problems.
In order to do so I:
* included strings.h and string.h in many files so various functions would be
defined
* Fixed model_t collision problem in cl_main.c (Solaris)
* com.c - corrected WORDS_BIGENDIAN spelling
* gl_draw.c - Use HAVE_GL_COLOR_INDEX8_EXT to avoid referencing
GL_COLOR_INDEX8_EXT when it isn't available
* net_udp.c - use socklen_t to appease AIX
