bundlerepo: rename "bundlefilespos" variable and attribute Strictly speaking, this variable tracks offsets within the changegroup, not the bundle. While we're here, mark a class attribute as private because it is. .. api:: Rename bundlerepo.bundlerepository.bundlefilespos to _cgfilespos.

test-pattern: actually update tests using the patterns We mass update the tests now. This will help the next soul touching the http protocol.

test-pattern: substitute the HTTP log timestamp too We add a pattern matching the infamous timestamp in http log. Now, we should be able to have change appears in https log without having to re-glob the whole thing over and over.

test-pattern: register the current the bundle2 capabilities string The bundle capabilites are sent with every getbundle ssh connection. Every time the protocol is updated, that string is altered. We get the part about bundle2 string replaced by $USUAL_BUNDLE2_CAPS$ so that we only have to change the substitution whenever this happens.

test-pattern: register current the bundlecaps string The bundle capabilites sent with every getbundle commands. Every time the protocol is updated, that string is altered. We get that string replace by $USUAL_BUNDLE_CAPS$ so that we only have to change the substitution whenever this happens.

test-pattern: substitute common compression list The compression list as to be matched with a glob because zstd might not be part of the option. By using a substitution for these, we won't have to re-glob them over and over.
