This (updated) patch to trunk adds support for Px and Ux (toggle
bprm_secure on exec) in the parser, As requested, lowercase p and u
corresponds to an unfiltered environmnet on exec, uppercase will filter
the environment. It applies after the 'm' patch.
As a side effect, I tried to reduce the use of hardcoded characters in
the debugging statements -- there are still a few warnings that have
hard coded letters in them; not sure I can fix them all.
This version issues a warning for every unsafe ux and issues a single
warning for the first 'R', 'W', 'X', 'L', and 'I' it encounters,
except when the "-q" or "--quiet" flag , "--remove" profile flag, or
"-N" report names flags are passed. Unfortunately, it made the logic
somewhat more convoluted. Wordsmithing improvements welcome.
