wireproto: add out-of-band error class to allow remote repo to report errors Older clients will still print the provided error message and not much else: over ssh, this will be each line prefixed with 'remote: ' in addition to an "abort: unexpected response: '\n'"; over http, this will be the '---%<---' banners in addition to the 'does not appear to be a repository' message. Currently, clients with this patch will display 'abort: remote error:\n' and the provided error text, but it is trivial to style the error text however is deemed appropriate.

util: move copymode into posix.py and windows.py reducing it to a NOP on Windows. This eliminates a pointless stat call on Windows and reduces the risk of interferring with other processes (e.g. AV-scanners, file change watchers).

util: factor new function copymode out of mktempcopy

revert: introduce short option -C for --no-backup Corresponds to -C of the update command. It's much more convenient to use: $ hg revert -aC than having to type $ hg revert -a --no-backup I think the 'no-backup' case is a frequent use case. Introducing short option -C here fits with the muscle memory we have from 'hg update -C', which is described there as "discard uncommitted changes (no backup)".
