patch: show lower-ed translated message correctly Before this patch, patch.filterpatch() shows meaningless translation of help message for chunk selection in some encoding. It applies str.lower() instead of encoding.lower(str) on translated message, but some encoding uses 0x41(A) - 0x5a(Z) as the second or later byte of multi-byte character (for example, ja_JP.cp932), and str.lower() causes unexpected result. To show lower-ed translated message correctly, this patch replaces str.lower() by encoding.lower(str).

wireproto: optimize handling of large batch responses Now that batch can be used by remotefilelog, the quadratic string copying this was doing was actually disastrous. In my local testing, fetching a 56 meg file used to take 3 minutes, and now takes only a few seconds.

cleanup: replace False identity testing with an explicit token object The recommended way to check default value (when None is not as option) is a token object. Identity testing to integer is less explicit and not guaranteed to work in all implementations.

devel: officially deprecate dirstate.write without transaction argument When we introduce the develwarning, we did not had an official deprecation API and infrastructure. We can now officially deprecate the old way with a version deadline.
