GNU automake 1.11 is the last release supporting "de-ANSI-fication"
using the included ansi2knr tool. And becuase we _want_ to support old
K&R platforms, we try hard to use this release of automake when
available to generate our build system.

- SC2006: Use $(..) instead of legacy `..`.
- SC2015: Note that A && B || C is not if-then-else. C may run
when A is true.
- SC2086: Double quote to prevent globbing and word splitting.
- SC2166: Prefer [ p ] && [ q ] as [ p -a q ] is not well defined.

For example OpenBSD uses a "autoconf" and "automake" wrapper script which
tells the user to set AUTOCONF_VERSION and AUTOMAKE_VERSION environment
variables. This patch enhances autogen.sh to not detect these wrapper
scripts as regular autoconf/automake commands but to set the required
environment variables after detecting the real "command-X.Y" commands.
Tested on OpenBSD 5.1.

"egrep -o" isn't portable and not available on OpenBSD, for example. So
let's use sed instead to get the automake version. The expression used
now is less specific but should work as well ...

This fixes
automake: warning: autoconf input should be named 'configure.ac',
not 'configure.in'
when running the autogen.sh script.

Starting with GNU automake 1.12, the "de-ANSI-fication support" has been
removed, which ngIRCd used to enable building itself on very old systems.
Now the problem is, that using automake >= 1.12 isn't working because of
the now unsupported M4 macros. Therefore the solution that this patch
implements is to dynamically generate the automake input files with our
own ./autogen.sh script:
configure.ng => configure.in
Makefile.ng => Makefile.am
This is quite an ugly approach, but it works and enables us to:
1. use current automake >= 1.12 for development and "private builds",
2. still build distribution archives using automake 1.11.x that have
"de-ANSI-fication support" enabled in the generated Makefile's.
And if you are using Makefile's generated with a automake version newer
than 1.11.x (without "de-ANSI-fication support"), the ./configure script
warns you not to use this generated build system to generate distribution
archives.
Drawback of this patch: you MUST use our autogen.sh script, you can't call
the autoconf/automake commands directly any more; but autoreconf should
still work ...

Now the ngIRCd release/version number is deduced from the "current"
annotated GIT tag; see "git describe --help" for details. This is the
same scheme the Linux kernel uses and gives much more details version
numbers for interim releases and inofficial source archives generated
using "make dist".
Please note: the version number is only updated it the autogen.sh
script is run; so after pulling in and pushing out new commits, you
should run ./autogen.sh!

On some systems (for example Gentoo Linux, FreeBSD, and OpenBSD), these
variables are used to select which version of GNU automake and autoconf
to use, but we shouldn't depend on a specific version -- instead we
should use the "system default". So probably it is up to the user to
set these variables accordingly to set up some wrapper scripts of his
operating system distribution.
