convert: drop a duplicate implementation of `dateutil.makedate()`
I noticed this because the signature generated by pytype recently changed to be
less specific. When the method was introduced back in 337d728e644f,
`util.makedate()` didn't take an optional timestamp arg. But now it does, and
the methods are the same (except the `dateutil` version validates that the
timestamp isn't a negative value). I left the old method in place in case
anyone has custom convert code that monkey patches it.

'''measure performance of Mercurial commands Using ``hgperf`` instead of ``hg`` measures performance of the target Mercurial command. For example, the execution below measures performance of :hg:`heads --topo`:: $ hgperf heads --topo All command output via ``ui`` is suppressed, and just measurement result is displayed: see also "perf" extension in "contrib". Costs of processing before dispatching to the command function like below are not measured:: - parsing command line (e.g. option validity check) - reading configuration files in But ``pre-`` and ``post-`` hook invocation for the target command is measured, even though these are invoked before or after dispatching to the command function, because these may be required to repeat execution of the target command correctly.
