hg: move peerschemes back to schemes This will avoid breaking things with extensions until peers are fully separated from repos.

hg: rearrange peer scheme lookup There is now only peer scheme lookup. Repository lookup goes through peer scheme lookup. When peer and repo types are finally separated, repo lookup will use peer.local() to get a repository object. The underbar is dropped so that extensions can patch the table.

forget, remove: don't note on nonexistent file twice before: $ hg forget foo foo: No such file or directory not removing foo: file is already untracked after: $ hg forget foo foo: No such file or directory

localrepo: local() returns self Temporary measure for introducing peers

tests: avoid instability in test-convert-cvs-synthetic

dispatch: propagate ui command options to the local ui (issue2523) so the ui object passed to pre/post python hooks has the verbose flag (and the rest) set correctly

mq: catch correct exception when calling changelog.rev()

rebase: preserve mq series order after rebasing (issue2849)
