Subject: [PATCH 1/6] Catch errors in setpagesize, .setpagesize and
setpagedevice and cleanup
Bug 699794 showed that attempt to change page size in SAFER mode when the
nulldevice was the currentdevice would leave 'false' on the stack. Run
.setdevice in stopped and clean up, and also clean up .setpagesize

Subject: [PATCH 3/6] Undefine some level2-related operators
These are only a partial set. Undefine them in both the level2dict and
systemdict. They are undef'd in gs_init.ps because they are used outside
the scope of just gs_lev2.ps
/.execform1
/.getdevparams
/.setuserparams2
/.startjob
/.checkFilePermitparams
/.checksetparams
/.copyparam
/.setpagesize
Rename .dict1 to .pair2dict and use immediate reference.
Undef these at end of gs_lev2.ps (should never make it into systemdict):

Subject: [PATCH 5/6] Fixed bug caused by the way .checksetparams was undef'd
Previously, had undef'd it by making it an operator.
Now just use an immediate reference and undef it in the gs_lev2.ps file.
This fixes bug introduced in commit fe4c47d8e25d6366ecbb5ff487348148b908a89e.
Undef'ing .checksetparams by making it an operator doesn't work right because
errors report .checksetparams as the offending function instead of
the operator that uses it (setsystemparams in this case).
This caused an error in file /tests_private/ps/ps3cet/27-09.PS on page 3,
where it reports the offending function of some error-handling tests.
Reporting function should be 'setsystemparams', not '.checksetparams' on
this page.

run (pdf_sec.ps).
