* Added Buuyo-Tama's shortlist for send/eof sockets (defined out for now).

* Replaced toupper/tolower in ladmin by TOUPPER/TOLOWER defines.

Shortlist:
It's a list of sockets that have data to send and/or are ready for eof processing.
It aims to reduce the amount of time spent on do_sendrecv, where it was spending ~13.5% of execution time on a server with 1k users at WoE.
thanks to Buuyo-tama for the profile info and code
