Add config option to specify amount of parallel download streams
It includes pacman.conf new 'ParallelDownloads' option that
specifies how many concurrent downloads cURL starts in parallel.
Add alpm_option_set_parallel_downloads() ALPM function that
allows to set this config option programmatically.
