Subject: [PATCH setup] Allow setup to parse more than 3 versions from the
  setup.ini file

This recognizes any "[foo]" line as introducing the information for another
version, which doesn't have one of the trust levels [curr], [prev] or
[test], and so isn't automatically selected when setup is told to install
all packages at that trust level (by default, [curr]).

Setup already does all the necessary sorting in version order etc. to use
these additional versions.

The value of <foo> carries no meaning, but the setup.ini specification
mandates the use of "[ver<digits>]".

	* PackageTrust.h (trusts): Add TRUST_OTHER.
	* inilex.ll: tokenize any other [version] as the T_OTHER token.
	* iniparse.yy: Add T_OTHER token and set package trust
	to TRUST_OTHER when it is used.

So, thinking about this change some more, I realize that there is a another way to do this, which doesn't break backwards compatibility with setup, by having multiple [prev] and [test] sections.

[1] doesn't say that these section names are unique, and setup doesn't require that, I'm going to claim that it's valid :)

Because of the way setup works, the last [test] section is the version which is selected when 'test' is selected, so a specific ordering of the sections would be required. The calm change to implement this is at [1].

So, for example we could have:

version: 250-0
version: 241-0
version: 243-0
version: 251-0
version: 252-0

250-0 would be current, 252-0 would be test, and the other versions would also be available to install.
