Modified Files:
src/sbbs3/userdat.c userdat.h
Log Message:
logoutuserdat() uses new function fputuserdat() to reduce open/lock/r/w ops

Reduces from 4 to 1 the open/lock/read/write/close operatons of the userbase (user.tab) file upon user log-off.

There's more places in sbbs where we do a lot of putuser* calls that could be (now) optimized in a similar fashion, but logoutuserdat() is called often (especially by the web, ftp, mail and services servers), so this one was obvious place to reduce contention on the userbase file.
