[PATCH] buildhistory.bbclass: add pkg_pre/postinst/rm contents

[PATCH] buildhistory.bbclass: add pkg_pre/postinst/rm contents

[Andreas Müller]

A use-case would have been [1].

The following tests were performed:
* image from scratch with old buildhistory contents
* image from scratch with buildhistory contents from scratch
* decrement a PR for a test recipe and check if the message
  'ERROR: Package version for xy went backwards' is displayed.

FWIW I hadn't forgotten about this feature request, although I hadn't got 
around to implementing it yet.

I haven't tested your patch but if I read it correctly you are writing the 
scripts out underneath the "value =" lines in the package data file. My concern 
with doing this is that it makes those files more difficult to parse. I had 
thought that the way to do it would be to write these scripts to separate files 
(e.g. latest.pkg_prerm, latest.pkg_postrm etc.). Would that be OK?

Cheers,
Paul
