Summary: \ifabsnum and \ifabsdim

Initial Comment:
Here is a small change file that implements two new
etex primitives :
  \ifabsnum 
  \ifabsdim 
Usage is the same as \ifnum and \ifdim. The only 
difference is that they negate the values if they are
negative before comparing.

intended usage: 

\ifabsdim \dimexpr \maxheight - \currentheight \relax < .5pt 
  assume that we're done 
\fi 

it can also be used to handle rounding errors when doing
roundtrip calculations
