Subject: makepkg: Separate vcs download and extract

Previously makepkg would clone vcs sources in the download function,
regardless of the noextract settings. Now the download_* functions only
download or update the vcs sources, and the new extract_* functions just
create working copies using the specified protocols. The extract_sources
function will call the needed extract function for the protocol
specified. The tarball extraction has also been moved into its own
extract_file function to keep things consistent.
