copies: improve logic of deciding copytracing on based of config options
Few months ago or maybe a year ago, I imported Fb's heuristics based copytracing
algorithms. While importing that, I renamed `experimental.disablecopytrace` with
`experimental.copytrace` and the behavior of the new config option was like
this:
* "heuristics" : Fb's heuristic copytracing algorithm
* "off" : copytracing is turned off
* something else: copytracing is on
This is the behavior right now also and this is bad because it hardcodes the
string 'off' to turn off the copytracing. On big repositories, copytracing is
very slow and people wants to turn copytracing off. However if the user sets it
to 'False', 'Off', '0', none of them is going to disbale copytracing while they
should.
I lacked the understanding of why this can be bad when I coded it.
After this patch, the new behavior of the config option will be:
* "heuristics": Fb's heuristic copytracing algorithm
* '0', 'false', 'off', 'never', 'no', 'NO', all the values which
repo.ui.configbool() evaluates to False: copytracing in turned off
* something else: copytracing is on
Since 'off' still evaluates to copytracing being turned off, this is not BC.
Also the config option is experimental.
