[patch@27694] VMS RMSEXPAND/PERL_CANDO fixes

This patch updates vms.c and vmsish.h:

In vmsish.h, add a new flag for RMSEXPAND to tell it not to do the
initial vmsify() step when it is not needed.

The ODS-2 only variant of the RMSEXPAND was missing some of the fixes
needed for using it to completely replace vmsify() for internal use
where the output needs to fit in 256 characters.

Perl_cando_by_name() was also calling vmsify() or rmsexpand() sometimes
on filenames that were already in the proper VMS format.

Removing the redundant or unneeded calls to vmsify() results on in the 6
minute reduction in the time needed to run the Perl test suite on my
system. The CPU time reduction can not easily be calculated because it
does not include subprocesses.

EAGLE> search thread.log; " time"
Elapsed CPU time: 0 00:02:18.80
Connect time: 0 01:15:17.85

EAGLE> search thread.log;-1 " time"
Elapsed CPU time: 0 00:02:20.64
Connect time: 0 01:21:26.60
