Issue3383: old-straight-flag + smaller Stem.thickness gives no output and huge over

This replaces the numerically imprudent y_intercept_ in buildings with
start_height_ and adapts calculations.
Issue 3406: convert-ly: Flag.transparent and Flag.color inherit from Stem

After issue 3395, Flag color and transparency does not need to be
changed in synch with Stem color and transparency.

Strictly speaking, it is overkill to change synchronized reverts along
with synchronized overrides: this does not work with things like

\override Stem.color = #red
\override Flag.color = #blue
...
\revert Stem.color
\revert Flag.color

where only the reverts get conflated (and thus Flag color stays in
place).  That's less than perfect, but probably better than leaving
reverts alone (for Flag.transparent, they might have been created
automatically by an earlier convert-ly rule).

Issue 3413: Remove patches from elisp

The files emacsclient.patch and server.el.patch applied to ancient
versions of Emacs.  They have been unnecessary for more than 8 years
now.  There is no conceivable use for them any more.
