commit 0def80f767b9a2cdfbc19d3a61433d1edd7a7998
Author: Greg Hudson <ghudson at mit.edu>

Modernize auth_acl.c
Change auth_acl.c to match current coding conventions. Use more
consistent identifier names, and drop the kadm5int_ prefix as the code
is now part of kadmind. Remove the acl_inited, acl_debug_level, and
acl_catchall_entry variables. Move global state into a structure, to
make it easier to migrate to a module handle later. Move
parse_restrictions() above parse_line() so it can later be used from
parse_line() without a forward declaration. Rewrite get_line() and
parse_line() to avoid the use of fixed-sized static buffers and
sscanf(). Add a parse_entry() helper to make memory management in
parse_line() easier. Add a free_acl_entry() helper (split out from
free_acl_entries()) to make error handling in parse_entry() easier.
Add a match_princ() helper to simplify find_entry().
Remove the GSS name translation wrapper in auth_acl.c. In the server
stubs, use handle->current_caller for the client principal. In the
iprop RPCs(), add a wrapper to parse the client display name before
calling acl_check().
