revlog: improve docstring for findcommonmissing

commands: bump copyright year

phase: mark messages for i18n

phase: fix up help string

phase: drop reference to working directory phase

phases: add a phases command to display and manipulate phases

annotate: append newline after non newline-terminated file listings The last line of a non newline-terminated file would mix with the first line of the next file in multiple-file listings before this patch. Possible compatibility issue: no longer possible to tell from the annotate output if the file is terminated by new line or not.

subrepo: avoid syncing bookmarks twice on clone (issue3191) Clone internally handles bookmark synchronization. (Fix spotted by Eric Blood)

revlog: clarify strip docstring "readd" -> "re-add" I misread it as "read".

merge with stable

filesets: use example with quotes for encoding predicate A user on IRC was confused that "encoding(ASCII)" works and "encoding(UTF-8)" fails with "parse error: encoding requires an encoding name".

phases: use graph and phase name in exchange test

phases: ``{phase}`` template keyword display the phase name ``{phaseidx}`` is providing the phase index as integer. This integer representation is useful when people need to use the fact that phase are ordered. Test keep using the number version for readability purpose.

phases: add a phasestr method on context

phases: add list of string to access phase name

phases: fix phase synchronization on push The bugs seemed to show up when element not in future common changeset should hold new hold phase data. The whole phase push machinery was rewritten in the process.
