Older versions of AsciiDoc used to literally pass double dashes when we
used them in our linkgit macros and manpage titles, but newer ones (the
issue was first reported with AsciiDoc 8.5.2) turn them into em dashes.
Define litdd (literal double-dash) custom attribute in asciidoc.conf to
work this around. While we are at it, fix a few double-dashes (e.g. the
description of "project--devo--version" convention used by tla, among
other things) that used to be incorrectly written as em dashes in the body
text to also use this attribute.

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.

This consolidates the common functionality from git-mergetool and
git-difftool--helper into a single git-mergetool--lib scriptlet.
