hg: rewrite "copystore()" with vfs This patch rewrites "copystore()" with vfs, because succeeding patch requires "lock.lock()" invocation with vfs. This patch uses 'dstbase + "/lock"' instead of "join()" with both elements even on Windows environment but it should be reasonable, because target files given from "store.copyfiles()" already uses "/" as path separator. "util.copyfiles()" between two vfs-s may have to be rewritten in the future.

localrepo: import "lock" module as "lockmod" for readability Before this patch, "localrepo.py" has many methods defining local variable "lock", even though it imports "lock" module as "lock". This ambiguity decreases readability.

transaction: take journal file path relative to vfs to use file API via vfs

vfs: add "chmod()"

vfs: add "isfile()"

transaction: unlink target file via vfs Before this patch, unlink target file is once opened before unlinking, because "opener" before vfs migration doesn't have "unlink()" function. This patch uses "vfs.unlink()" instead of "open()" and "fp.name".

relink: abort earlier when on different devices (issue3916) Add a first check of the devices before collecting candidate files. This is much quicker when big repos are on different devices. Keep the existing check in prune. It checks for same device of the files. This could probably be different in a special repo store (with symlinks).

localrepo: prevent to copy repo local config, copy baseui instead Copying a repos local configuration to another repo is a bad idea because the 2nd repo gets the configuration of the first. Prevent this by really calling repo.baseui.copy when repo.ui.copy is called. This requires some changes in commandserver which needs to clone repo.ui for rejecting temporary changes. This patch has its roots back in the topic "repo isolation" around f0564402d059 and was suggested by mpm.

doc: show details of command options in pages generated by docutils Before this patch, HTML/man pages generated by docutils don't show details of each command options, whether it should take argument or not for example, even though "hg help" does. This patch shows details of command options as same as "hg help" shows. This patch uses "--option <VALUE[+]>" style instead of "--option <VALUE> [+]" used in output of "hg help", because docutils requires that option argument strings starts with "<" and ends with ">".

Makefile: intermediate steps work with temporary copy of hg.pot In case of abortion or a failing step, the target file remains untouched instead of being in an intermediate state.
