Style change: return(x) --> return x

This was discussed and more or less agreed upon on the mailing list. A
huge checkin, but if we just do it and let people adjust the pain will

The following semantic patch was used to do the change, along with some
hand-massaging in order to preserve parenthesis where appropriate:

The semantic match that finds this problem is as follows, although some
hand-massaging was done in order to keep parenthesis where appropriate:

A macros_file was also provided with the following content:

Additional steps taken, mainly for ASSERT() macros:
$ sed -i -e 's#return(NULL)#return NULL#' lib/libalpm/*.c
$ sed -i -e 's#return(-1)#return -1#' lib/libalpm/*.c
