Introduce -D, --database

The request of FS#12950 is implemented.

On the backend side, I introduced a new function, alpm_db_set_pkgreason(),
to modify the install reason of a package in the local database. On the
front-end side, I introduced a new main operation, -D/--database, which has
two options, --asdeps and --asexplicit. I documented this in pacman manual.
I've created two pactests to test -D: database001.py and database002.py.
