py3: convert opts to bytes in cmdutil.dorecord() commands.commit() calls cmdutil.dorecord() where opts are passed as unicodes being keyword arguments. This patch converts them back to bytes as they are required.

py3: make sure opts are passed and used correctly in help command opts are converted back to bytes in help.help_() where they are used. Before that it's ensured that we have a bytes value for keep variable.

py3: handle opts uniformly in commands.py Since keyword arguments can't be bytes on Python 3, we converted then to unicodes before passing into different command functions. We need to adopt a certain pattern to convert opts back to bytes. Following are some of the functions which are called from inside these command functions and should always be feeded bytes to follow the right behaviour. ui.fomattter() scmutil.match() patch.diffallopts() hg.peer() cmdutil.{show_changeset|copy|graphrevs|checkunsupportedflag} server.{createservice|runservice} There are few commands which are left out where opts is again passed to a function as keyword arguments or converting opts back to bytes is kind of not necessary. Those are cat, revert, help, unbundle and rollback. Following patches will deal with them. This patch apart from these five commands, convert opts back to bytes for rest of the commands. This fixes a lot of things which are hidden like --git works now. Similarly more flags of commands which run on Python 3 currently get fixed.

webcommands: use fctx.isbinary

annotate: use fctx.isbinary

fileset: use fctx.isbinary instead of util.binary(fctx.data()) filectx provides "isbinary" to test if the data is binary. Let's use it. This enables other filectx implementations (like LFS) to override the isbinary test.

internals: document that "branches" is a legacy wire command Modern clients use a different discovery mechanism.

match: make subinclude construction lazy The matcher subinclude functionality allows us to have .hgignore files that include subdirectory hgignore files. Today it parses the entire repo at once, even if we only need to test a file in one subdirectory. This patch makes the subinclude tree creation lazy, which speeds up matcher creation significantly in large repos with very large trees of ignore patterns.

bisect: allow resetting with unfinished graft/rebase/etc "hg bisect --reset" just deletes the state file (it doesn't move back to the starting point like rebase does); it can not conflict with an ongoing rebase etc. checkunfinished() has this documentation: It's probably good to check this right before bailifchanged(). So that's where I moved it.
