bundlerepo: properly extract compressed changegroup from bundle2 Before this bundle repository were unable to work with compressed bundle2. We use the same approach as with bundle1, we extract the changegroup in uncompressed form into a temporary file.

bundle2: make unbundle.compressed return True when compressed We were returning 'False' in all cases, even when the bundle2 was actually compressed.

bundlerepo: uncompress changegroup in bundle1 case only Uncompressing bundle2 needs to be handled differently.

bundlerepo: move temp-bundle writing logic into a closure We will reuse this logic for bundle2

shelve: properly process bundle2 bundle

histedit: properly apply bundle2 backups If the histedit fails, we restore a backup. We make sure this backup bundle can be in bundle2 format as general delta will require.

strip: pass source and url to bundle2 processing Restoring from a 'bundle2' was missing this data.

unbundle: use 'url' argument with applybundle This will let the hook get access to the 'url' value.

applybundle: take url as argument We allow specifying the url to carry it to hooks. This gets us closer to 'bundle1.apply(...)' and will allow us to remove regressions in multiple place where we forget to pass the url to hooks.

unbundle: use 'source' argument with applybundle This will let the hook get access to the 'source' value.
