recover: add a --[no-]verify flag
For trivial cases, the cost of the verify run after `hg recover` is getting in
the way. In addition for very large repositories, the cost is simply too high
to be paid, making `hg recover` an unusable commands.
We introduce a --verify flag, set by default. If is automatically associated
with a --no-verify flag that one can use to skip the verify step.
We might consider changing the default behavior in the future. However this is
out of scope for this series.

'''http authentication with factotum This extension allows the factotum(4) facility on Plan 9 from Bell Labs platforms to provide authentication information for HTTP access. Configuration entries specified in the auth section as well as authentication information provided in the repository URL are fully supported. If no prefix is specified, a value of "*" will be assumed. By default, keys are specified as:: proto=pass service=hg prefix=<prefix> user=<username> !password=<password> If the factotum extension is unable to read the required key, one will be requested interactively. A configuration section is available to customize runtime behavior. By default, these entries are:: [factotum] executable = /bin/auth/factotum mountpoint = /mnt/factotum service = hg The executable entry defines the full path to the factotum binary. The mountpoint entry defines the path to the factotum file service. Lastly, the service entry controls the service name used when reading keys.
