intrinsic functions not yet documented

[Daniel Franke]

Hi all.

While preparing the docs for idate/itime, I found that there are far more 
intrinsics implemented than documented in the .texi file. Below, I assembled 
a list of the intrinsics not yet documented. If someone could check this list 
and remove anything that should not be mentioned for some reason (duplicates, 
not yet implemented, obsolete, whatever) and add those I might have missed?

Btw, is there any specific schedule for the 4.1.2 release? 

Regards
	Daniel
