autotoolize

I'm trying to get the Git repository to be better than what it was when I was
using Subversion - not that it was a problem with Subversion per se, it's just
that I've embarked on a big change, so I might as well try and fix this while
I'm at it.

Basiclly, I want only the source files to be in the repository: anything that
can be generated should not be there, because i) it's  a waste of space, and
ii) local versions may conflict.

The idea is, then, that after doing a git clone, you should just need to run
./configure -- since this is what happens when you compile from source.

So, my repository being in an unknown state, I did:

$ autoreconf --install

which should make it ./configure - runnable. Then I did

$ ./configure && make check

All went smoothly, so

$ make distclean.

This I'll use as a starting point. I did:

$ git add .
$ git st

...
#	new file:   autom4te.cache/output.0
#	new file:   autom4te.cache/output.1
#	new file:   autom4te.cache/requests
#	new file:   autom4te.cache/traces.0
#	new file:   autom4te.cache/traces.1
...

Hmm, I have an inkling that all the cache contents should not really be under
version control, so I'll ignore them:

$ git reset HEAD autom4te.cache/*
$ cat > .gitignore
autom4te.cache

And then I committed.
