[Dovecot] Version numbering

[Eric Rostetter]

Quoting Timo Sirainen <tss at iki.fi>:

> a) Postfix-style: "1.1.UNSTABLE.YYYYMMDD" -> 1.1.0 (stable)

Not my favorite, but works for me.  Seems good for Timo, since he
likes to release dated snapshots anyway.

> b) Odd-even numbering: 1.1.x (unstable) -> 1.2.0 (stable)

I don't like this, as the average new user has no idea that the odds
are unstable, and runs them, then gets flamed for it, etc.  No matter
how well you document it on the web/wiki, people are going to mistakenly
run the odd number releases and get in trouble.

Why not just put actual (stable) releases in the "releases/" directory, and
put the "unstable" releases in another directory (unstable, testing, or
some such).
