Added ilaenv2stage.f to enable the extraction of 2stage machine dependent
variables from the 2stage solver without having to rely on compiling the
entire library with the recursive flag.
Secondly, all calls to ILAENV( 17 <= 21, ...) have been fixed to
use the corresponding ILAENV2STAGE routine by translating ISPEC by -16
I.e.
ILAENV( 17, ...) == ILAENV2STAGE( 1, ...)
Also fixed the documentation of ilaenv.f to specify the cases of ISPEC > 16.

This is really old school, but a lot of times we have users sending us
copy pasting of codes, and that is the only way to know the version of
the code.
