sepolicy: Make manpage and transition faster
SETools4 and Python 3 versions of map() and filter() uses iterators to
generates query results and these iterators can't be imply re-used. It
makes manpage and transitions operations really slow as they do lot of queries.
This patch changes it in the way that it caches results in lists for all
types, allow rules and transitions first and use cached results to
filter them using Python's filter() function.
Before:
$ time sepolicy manpage -d httpd_t sshd_t init_t
real 0m53.486s
user 0m53.171s
sys 0m0.054s
After:
$ time sepolicy manpage -d httpd_t sshd_t init_t
real 0m10.532s
user 0m10.368s
sys 0m0.114s
