hgweb: use an extensible list of file to check for refrash
The refresh feature was explicitly testing if '00changelog.i' and 'phasesroots'
changed. This is overlooking other important information like bookmarks and
obstore (bookmark have their own hack to work around it).
We move to a more extensible system with a list of file of interest that will be
used to build the repo state. The system should probably move in a more central
place so that the command server and other system are able to use it.
Extensions write will also be able to add entry to ensure that changes to
extension data are properly detected.
Also the current key (mtime, size) is notably weak for bookmarks and phases
whose files can easily change content without effect on their size.
Still, this patch seems like a valuable minimal first step.
