[icqlib-dev] More portability fixes

[Eric W. <war...@ya...>]

Hi,

Some systems don't have socklen_t typedef'd, and so fail when compiling
and socketmanager.c and files that include socketmanager.h (looks like
just icqlib.c). Looks like this got changed to int in tcplink.c a while
back; on my system it's typedef'd as unsigned int though.
