manifest: allow specifying the revlog filename Previously we had hardcoded the manifest filename to be 00manifest.i. In our external treemanifest extension, we want to allow writing a treemanifest side by side with a flat manifest, so we need to be able to store the root revisions at a different location (in our extension we use 00manifesttree.i). This patches moves the revlog name to a parameter so we can adjust it.

py3: drop unrequired code from __init__.py Once we are using pycompat.open(), we don't need this hack to convert the second argument to unicodes. So removing this.

py3: add pycompat.open and replace open() calls open() requires mode argument as unicodes on Python 3. This patch introduces pycompat.open() which is inserted to files using transformer and replaces builtins.open() calls.

localrepo: deprecate 'repo.opener' (API) The "new" 'repo.vfs' attribute have been around for almost 5 years. I think we can deprecate the old form now ;-)

clonebundle: use 'repo.vfs' instead of 'repo.opener' The later is a 5 years old form.

localrepo: deprecated 'repo.wopener' (API) The "new" 'repo.wvfs' attribute have been around for almost 5 years. I think we can deprecate the old form now ;-)
