maint: describe new versioning and branching scheme, and adjust to it
See discussion about automake bug#13578 for more details and background.
Basically, for the versioning scheme:
- micro versions only for bug and regression fixing;
- minor versions for new backward-compatible features, and new
non-fatal deprecations;
- major versions for backward-incompatibilities, complex new
features, and major refactoring.
And for the git branching scheme:
+ branch 'next' is for the upcoming major version;
+ branch 'master' is now for the upcoming minor version;
+ branch 'maint' is for the upcoming micro (bug-fixing) version;
+ the merging hierarchy is: 'maint' -> 'master' -> 'next'.
* HACKING (Automake versioning and compatibility scheme): New.
(Working with git): Adjust.
* NEWS: Update and fix.
* aclocal.in: Adjust some "FIXME" messages.
* automake.in: Likewise.
* m4/mkdirp.m4: Likewise.
* t/aclocal-acdir.sh: Likewise.
* t/aclocal-macrodir.tap: Likewise.
* t/aclocal-macrodirs.tap: Likewise.
* lib/Automake/Options.pm: Likewise.
* m4/internal/ac-config-macro-dirs.m4: Likewise.

aclocal: AC_CONFIG_MACRO_DIRS: work around autom4te option parsing bugs
The autom4te program coming with autoconf 2.68 and earlier had a bug
which caused the "-" command line argument (with which we tell it to
read some input from from standard input) to aways be pushed at the
*end* of the command line, regardless of where the user specified it
(that bug was fixed by autoconf commit 'v2.68-120-gf4be358', "getopt:
new Autom4te::Getopt module").
This broken semantics conflict with our usage in aclocal, where we
need to pass some input to the invoked autom4te program early, and
have so far been using the stdin to do so. Now we start using an
external file instead.
* m4/internal/ac-config-macro-dirs.m4: New file, contain a fallback
definition of the AC_CONFIG_MACRO_DIRS macro for older autoconf
releases.
* aclocal.in (trace_used_macros): When invoking autom4te, use that
file instead of "abusing" standard input.
* Makefile.am (dist_automake_ac_DATA): Rename ...
(nobase_dist_automake_ac_DATA): ... like this.
Add 'm4/internal/ac-config-macro-dirs.m4' to it.
* t/aclocal-acdir.sh: Adjust to avoid spurious failures.
