pgbench: Allow changing weights for scripts
Previously, all scripts had the same probability of being chosen when
multiple of them were specified via -b, -f, -N, -S. With this commit,
-b and -f now search for an "@" in the script name and use the integer
found after it as the drawing probability for that script.
(One disadvantage is that if you have script whose names contain @, you
are now forced to specify "@1" at the end; otherwise the name's @ is
confused with a weight separator. We don't expect many pgbench script
with @ in their names in the wild, so this shouldn't be too serious a
problem.)
While at it, rework the interface between addScript, process_file,
process_builtin, and findBuiltin. It had gotten a bit out of hand with
recent commits.
