largefiles: use "outgoinghooks" to avoid redundant outgoing check
Before this patch, "hg outgoing" invokes "findcommonoutgoing()" not
only in "commands.outgoing()" but also in
"overrides.overrideoutgoing()" (via "getoutgoinglfiles()"), when
largefiles is enabled. The latter is redundant.
This patch uses "outgoinghooks" to avoid redundant outgoing check.
Newly introduced function "overrides.outgoinghook()" is registered
into "outgoinghooks" to get the result of outgoing check in
"commands.outgoing()".
It invokes "lfutil.getlfilestoupload()" directly with the result of
outgoing check to avoid redundant outgoing check in
"getoutgoinglfiles()": "sort()" is needed, because
"lfutil.getlfilestoupload()" doesn't sort the result of it.
This patch also omits "if toupload is None" ("No remote repo") case,
because failure of looking remote repository up should raise exception
in "commands.outgoing()" before invocation of "outgoinghooks".
Newly added "hg outgoing --large --graph" tests examine
"outgoinghooks" invocations in "hg outgoing --graph" code path.
