Dan McGee 0303b26b1e 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
end soon enough. Rebasing should be relatively straighforward for anyone
that sees conflicts; just be sure you use the new return style if
possible.

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:

- return(a);
+ return a;

// </smpl>

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
