hg: update to use vfs functions in shared destination repository

This patch uses rvfs with base as root of .hg directory in shared destination
repository to update filesystem function with vfs. Some methods are changed to
use vfs functions with rvfs.

"roothg" shouldn't be removed in this patch, because it is still
referred from others until next (#4) patch (see writing 'requires' and
'sharedpath' out below in this patch !)

Name of "rvfs" seems to make relation with "dstvfs" weak.

What about "dstwvfs" and "dstvfs" to follow field names of
localrepository, instead of "dstvfs" and "rvfs" ?


Or what about passing ".hg" to "dstvfs" explicitly like below, because
there are at most four "rvfs" users below ? (this way may be a little
redundant ...)

       dstvfs.makedir('.hg')

(in next patch)

       dstvfs.write('.hg/requires', requirements)
       dstvfs.write('.hg/sharedpath, requirements)

Additional expandpath is not explicitly required, since path is
already expanded at previous stage in share itself.

I will take care of this in V2.

I used term 'dstvfs because it was already used in copystrore in hg.py
but I must agree that destvfs is better suited.

Sounds good as there are only few users with repository path.
