util: fall cleaning on single file programs
* Add a bunch of static declarations where possible * Fix void functions to be proper syntax, e.g. void func(void) * Consistency fixes (such as argv references) * Remove dead str_cmp() function from testdb * Remove unneeded config.h header includes * vercmp: remove completely unnecessary string copying Signed-off-by: Dan McGee <dan@archlinux.org>
