largefiles: setup "largefiles" feature in each repositories individually
Before this patch, if largefiles extension is enabled once in any of
target repositories, commands handling multiple repositories at a time
like below misunderstand that "largefiles" feature is supported also
in all other local repositories:
- clone/pull from or push to localhost
- recursive execution in subrepo tree
This patch registers "featuresetup()" into "featuresetupfuncs" of
"localrepository" to support "largefiles" features only in
repositories enabling largefiles extension, instead of adding
"largefiles" feature to class variable "_basesupported" of
"localrepository".
This patch also adds checking below to the largefiles specific class
derived from "localrepository":
- push to localhost: whether features supported in the local(= dst)
repository satisfies ones required in the remote(= src)
This can prevent useless looking up in the remote repository, when
supported and required features are mismatched: "push()" of
"localrepository" also checks it, but it is executed after looking up
in the remote.
