largefiles: put whole "hgmerge" process into the same "wlock" scope
Before this patch, there are two distinct "wlock" scopes below in
"hgmerge":
1. "merge.update" via original "hg.merge" function
2. "updatelfiles" specific "wlock" scope (to synchronize largefile
dirstate)
But these should be executed in the same "wlock" scope for
consistency, because users of "hg.merge" don't get "wlock" explicitly
before invocation of it.
- merge in commands
This patch puts almost all of the original "hgmerge" implementation into
"_hgmerge" to reduce changes.
