largefiles: reuse "findcommonoutgoing()" result at "hg push"...
largefiles: reuse "findcommonoutgoing()" result at "hg push" Before this patch, "hg push" invokes "findcommonoutgoing()" not only in "exchange.push()" but also in "lfilesrepo.push()", when largefiles is enabled. The latter is redundant. This patch registers own "prepushoutgoinghook" function into "prepushoutgoinghooks" of "localrepository" to reuse "findcommonoutgoing()" result. "prepushoutgoinghook" omits "changelog.nodesbetween()" invocation, because "findcommonoutgoing()" invocation in "exchange.push()" takes "onlyheads" argument and it considers "nodesbetween()".
