largefiles: allow the archiving of largefiles to be disabled
There are currently no users of this, but it is a necessary step before
converting extdiff to use archive. It may be useful to add an argument to
extdiff in the future and allow largefiles to be diffed, but archiving
largefiles can have significant overhead and may not be very diffable, so
archiving them by default seems wrong.
It is a mystery to me why the lfstatus attribute needs to be set on the
unfiltered repo. However if it is set on the filtered repo instead (and the
filtered repo is passed to the original command), the lfstatus attribute is
False in the overrides for archival.archive() and hgsubrepo.archive() when
invoking the archive command. This smells like the buggy status behavior (see
67d63ec85eb7, which was reverted in df463ca0adef). Neither the status nor
summary commands have this weird behavior in their respective overrides.

'''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.
