tcsysmon

This is a rewrite based on an older version of WmSysMon, to make it use less CPU time, and to make it work with new (2.4) kernels. This was not tested on 2.2 kernels and is presumed not to work. See readme for info.

In this release, use of devfs is automatically detected, and the proper device file is opened.

A Makefile fix to solve include problem with glibc 2.1.93, and compilation fixes for 2.4.0-test9 and newer kernels.

Documentation updates, a minor code cleanup, optimizations and updates, a fix for a bug with SMP systems where only last CPU would be counted for IRQ statistics, and updates to the tcsysmon shell script to check if module has been loaded. Note: if you just upgraded to 2.4.0-test6pre5 and tcsysmon stopped working (wrong lights light up, IRQ statistics are incorrect), recompile both monitor and tcsysmon; the kstat structure has been changed. Users of wmmon-tcm will also need to recompile it.

A fix for a stupid typo in monitor.c which prevented compiles under 2.2 kernels and a small Makefile fix.
