largefiles: call readstandin() with changectx itself instead of rev or node

readstandin() takes "node" argument to get changectx by "repo[node]".

There are some readstandin() invocations, which use ctx.node(),
ctx.rev(), or '.' as "node" argument above, even though corresponded
changectx object is already looked up on caller side.

This patch calls readstandin() with already known changectx itself, to
avoid meaningless re-construction of changectx (indirect case via
copytostore() is also included).

BTW, copytostore() uses "rev" argument only for readstandin()
invocation. Therefore, this patch also renames it to "revorctx" to
indicate that it can take not only revision ID or so but also
changectx, for readability.

cHg
===

A fast client for Mercurial command server running on Unix.

Install:

 $ make
 $ make install

Usage:

 $ chg help                 # show help of Mercurial
 $ alias hg=chg             # replace hg command
 $ chg --kill-chg-daemon    # terminate background server

Environment variables:

Although cHg tries to update environment variables, some of them cannot be
changed after spawning the server. The following variables are specially
handled:

 * configuration files are reloaded automatically by default.
 * CHGHG or HG specifies the path to the hg executable spawned as the
   background command server.

The following variables are available for testing:

 * CHGDEBUG enables debug messages.
 * CHGSOCKNAME specifies the socket path of the background cmdserver.
 * CHGTIMEOUT specifies how many seconds chg will wait before giving up
   connecting to a cmdserver. If it is 0, chg will wait forever. Default: 60
