are actually passed to each service function in the classic (argc,
argv) form. The only place where the compiler could have caught this
used a type cast, and it did not show up in testing either because all
of the modules I tested use openpam_get_option(3) instead of
manipulating argv directly.
The cleaned-up policy parsing code remains in place, but options are
once more stored as strings, pretty much the way they appear in the
policy file, except that quotes are stripped.

bonus, it should now be much easier to read and understand.
This also changes the way options are stored: they are now stored as a list
of { key, value } pairs rather than "key=value" strings.

would previously return 0 because it expected the next character after
the matched word to be a space.

loader, reducing the number of times each file is read. Also fix
a few minor nits (such as making facility names and control flags
case insensitive like they are in Solaris).

reporting: error messages relating to policy files now include line
numbers, and the parser will warn about invalid facility names.
Also fix an off-by-one bug in the option handling code.

that clears the pointer after freeing the memory it pointed to.

use it to fill the gaps in incomplete policies as well as to replace
missing ones.
