Add the linux 2.6.x stuff (not used by default!):

 - TLS - complete
 - pid/tid mangling - complete
 - thread area - complete
 - futexes - complete with issues
 - clone() extension - complete with some possible minor issues
 - mq*/timer*/clock* stuff - complete but untested and the mq* stuff is
   disabled when not build as part of the kernel with native FreeBSD mq*
   support (module support for this will come later)

Tested with:
 - linux-firefox - works, tested
 - linux-opera - works, tested
 - linux-realplay - doesnt work, issue with futexes
 - linux-skype - doesnt work, issue with futexes
 - linux-rt2-demo - works, tested
 - linux-acroread - doesnt work, unknown reason (coredump) and sometimes
   issue with futexes
 - various unix utilities in linux-base-gentoo3 and linux-base-fc4:
   everything tried worked

On amd64 not everything is supported like on i386, the catchup is planned for
later when the remaining bugs in the new functions are fixed.

To test this new stuff, you have to run
	sysctl compat.linux.osrelease=2.6.16
to switch back use
	sysctl compat.linux.osrelease=2.4.2

Don't switch while running a linux program, strange things may or may not
happen.
