mergetool used /dev/tty to switch back to receiving input from the user
via inside a block with a redirected stdin.
This harms testability, so change mergetool to save its original stdin
to an alternative fd in this block and restore it for those sub-commands
that need the original stdin.
Includes additional compatibility fix from Jonathan Nieder.

Even though this script is expected to be sourced instead of
executed on its own, the #!/bin/sh line provides simple
documentation about what format the file is in.
In particular, the lack of such a line was confusing the
valgrind support of our test scripts, which assumed that any
executable without a #!-line should be intercepted and run
through valgrind. So during valgrind-enabled tests, any
script sourcing this file actually sourced the valgrind
interception script instead.

Use a case statement instead of calling grep to find out if the editor's
name contains the string "vim". Remove the check for emacs, as this
branch did the same as the default one anyway.

The ecmerge documentation mentions the following form:
ecmerge --mode=diff2 $1 $2
Since git-difftool is about diffing, we should use that instead
of --mode=merge2. Likewise, this drops the $MERGED argument to
emerge, as discussed on the git list ($gmane/117930).

The mergetool--lib scriplet was tricky to use because it relied upon
the existance of several global shell variables. This removes more
global variables so that things are simpler for callers.
A side effect is that some variables are recomputed each time
run_merge_tool() is called, but the overhead for recomputing
them is justified by the simpler implementation.

git-difftool--helper into a single git-mergetool--lib scriptlet.
