This wraps up makefile-centric config/build munging, modulo bugfixes.
Most changes should be uncontroversial, though i'd like to point out
a bugfix that may prove unpopular (see below for commit log entry).
Feedback welcome.
Next series will be -config-N, which will focus on configure.ac.
The primary goal of the series will be to remove DVC-maintainer
stuff (such as makeinfo(1) detection) from the configuration
process, so that DVC-end-user doesn't have to deal w/ it.
For -config-1, i don't expect any changes outside configure.ac
itself and the collaborating Makefile.in files.
For -config-2, however, i envision things like baz-vs-tla checks
to be moved out of configure-time completely (to run-time), which
would likely involve lisp/*.el munging. I will be asking for
guidance then, so don't be surprised when Janitorial Ignorance
rears its head!
In any case, if anyone has any configuration hints / pointers /
wish-list items, now is a good time to make them known.

Consolidate build functionality into dvc-build.el.
In the process of integrating package-maint.el, we also fix a small
bug. Consider the case where bot.el requires mid.el requires top.el.
That is, bot.el has (require 'mid);
and mid.el has (require 'top).
Now we touch top.el. Previously, this would cause recompilation of
top.el and mid.el, only, and not bot.el. That is, the files to be
(re-)compiled consisted of the root set (top.el) and their immediate
dependents (mid.el).
This is perfectly sufficient except in the case where mid.el defines
macros whose definitions change due to changes in top.el, and whose
definitions are used by bot.el. Do such cases exist? We don't know;
we don't do anything to identify them. Thus, IF they do exist, not
compiling bot.el MAY introduce skew problems.
Two resolutions come to mind to achieve assurance that skew problems
cannot exist: a/ identify this case and recompile bot.el if needed;
b/ recompile bot.el unconditionally.
We choose b/ because a/ is hard. Practically, this means we compute
the complete fan-out of the root set and in most cases (where there
is no macro dependency as described above), recompile more files than
strictly necessary. This is the cost of erring on the safe side.
* lisp/dvc-build.el: Signal error if loaded interactively.
Integrate contrib/package-maint.el; no longer require `package-maint'.
Push nil on `load-path' last.
When adding `otherdirs', remove null strings from `split-string' rv.
Combine top-level conditional of Emacs-specific byte-compiler fixups.
(srcdir, otherdirs): Signal error if env var not set.
(builddir, contribdir, loaddir): Delete vars.
(package-maint-pkg, no-compile-files): Delete vars.
(zonk-file, f-set-difference, f-intersection, srcdir/): New funcs.
(--warnings): Rename from `package-maint-compile-warnings'.
(--autoloads-filename): Rename from `package-maint-load-file'.
(--custom-autoloads-filename): Rename from `package-maint-cus-load-file'.
(--to-compile): Rename from `package-maint-files';
compute value once, at dvc-build.el-load time.
(byte-compile-dest-file): Rewrite.
(missing-or-old-elc): Rename from `package-maint-changed-source-p';
use `remove-if-not'.
(dvc-build-compile): Rewrite.
