Log Message:
sbbs3 servers: ctrl/clear semfile + outcome logging for per-IP clear

Extend the ctrl/clear semfile (and its .ftp/.mail/.web/.services/.term variants) so every TCP server reads it, not just the terminal server.
Each server now initializes, primes, polls, and frees its own clear_attempts_semfiles list alongside its existing
shutdown/pause/recycle ones, sharing the parsing logic introduced for
main.cpp in cdd821ac1.

Move readSemfileIp() from main.cpp's static helper out to
xpdev/semfile.{h,c} as semfile_first_line(), so all five servers can
use it without duplicating the fopen/fgets/truncsp boilerplate.

Log the outcome of each per-IP clear: report how many entries were
removed (which may legitimately be zero if the IP was never on the
list), or warn if the address failed to parse. Makes it possible to
tell from the log whether a clear request actually targeted anyone.
