Removes partial long options from the tools (#872)

Some of the command-line tools would allow partial long options (e.g.,
--datas instead of --dataset). These were inconsistently implemented,
difficult to maintain, and occasionally blocked useful long options.
They have been removed from all the tools.

NOTE: This change should NOT be merged to 1.12 or earlier.
