[PATCH 0/7] Fix first boot deferral and postinst error reporting

[Alexander Kanavin <alexander.kanavin@linux.intel.com>]

This patchset is aiming to fix long-standing problems with package post-installation
scriptlets:

1) The way to defer them to first boot is to issue 'exit 1'. On the other hand,
'exit 1' is also the way to indicate an error in the script. The patches decouple
these two things.

2) Scriptlets should be executed using '-e', otherwise failing commands in
the middle of the scriptlet will not be reported as such.

3) The patchset also adds a convenient shortcut for deferring scriptlets to
first boot execution:

pkg_postinst_ontarget_PACKAGENAME() {
      # Actions to carry out on the device go here
      ....
}

The following changes since commit 0c537554fc2cf58a9cbfeaf39ed918c607483dce:
