libmakepkg: move functions for extracting pkgbuild attributes
Also rename some functions for clarity: funcgrep -> grep_function extract_global_var -> extract_global_variable extract_function_var -> extract_function_variable pkgbuild_get_attribute -> get_pkgbuild_attribute Signed-off-by: Allan McRae <allan@archlinux.org>
