[yocto] Last minute changes - Review Request

[Richard Purdie]

Coming up to release there are a few things that the extended testing
has shown up which we have fixes for and which we should consider
including in the release. I also finally got around to doing the final
sstate stress testing and found several problematic issues. Given that
sstate and checksums are a significant feature of this release, I'd
really like them to work as well as we can make them. Prior to this I
had stress tested the backend up not the use of the packages. These
changes don't change any sstate packages themselves, just the use of
them.

Since we already have the release images prepared and tested and these
are not going to change, the criteria for potential changes:

a) We can unit test the changes and be confident they don't 
   break/regress things.
b) They fix important bugs that the user can easily run into
   or that make the project look bad.
c) The changes are small, well documented and are obviously correct 
   looking at the code/patch.
d) The don't change the generated images.

I'm proposing the following, for each I've provided a rationale:

Printing "fatal:" to new users is worrying

Users can easily hit the sanity warning about missing 32 bit libs. We
don't need this functionality at this time so we might as well turn it
off by default

Doesn't change the build output but fixes a build issue people can
easily run into in from scratch builds due to a missing dependency.

Removes the "WARNING: Function do_build doesn't exist" message which
could worry users and looks bad

Several complaints have been received about the inability to easily
delete sstate and DL_DIR contents to recover from failures. This adds a
cleanall task which does this. Downside is that this is undocumented.

[Reported by Darren and others, run into by Dirk]

http://git.pokylinux.org/cgit/cgit.cgi/poky/commit/?id=f806c499c031fe0c4da001d41bce635088a90c52

Fixes an sstate bug where the do_package sstate packages don't install
correctly. A user could hit this if cleaning and rebuilding a package
under certain circumstances.

http://git.pokylinux.org/cgit/cgit.cgi/poky/commit/?id=13f116b1ad6a955b07d4cbaba85879913c30e1ee

Fixes an issue with sstate where rebuilding a package using partially
prebuilt state would break rpm generation and silently remove all the
rpm packages.

Fixes a typo spotted in the debian packaging backend. We don't use this
by default but it should be fixed.

User testing keeps showing up issues with the pseudo directory creation
failing to happen. This patch solves the problem in a brute force
fashion, once and forall.

[Reported by Mark and others]

http://git.pokylinux.org/cgit/cgit.cgi/poky/commit/?id=3f599b3f6a47286277cdaa8503f8a8da024eadd4

Fixes an sstate issue seen on the Poky mailing list where file:// sstate
mirrors wouldn't work.

Just changes a log level to make the output from sstate slightly more
readable.

I'm not happy about being in this position and I know Dave will be very
nervous about these late changes. To mitigate this I'd like to propose
that a selection of people (Josh, Mark, Saul?) review these changes and
report back on whether they feel these are appropriate and also give the
build some testing with these applied.

Cheers,

Richard
