* avoid repeated regex compilations (regex for search string do not
 change while scanning the package database)

* remove needless string duplication (regex function do not change target
 string nor free them)

* code cleanup

This patch improves search performance:

bash-3.2$ time ./src/pacman/pacman.static.old -Ss "(database|web).*server" >/dev/null

bash-3.2$ time ./src/pacman/pacman.static -Ss "(database|web).*server" >/dev/null

real    0m0.777s
user    0m0.456s
