Tinfoil rework - OE-Core changes

Tinfoil is an API that allows you to write simple utilities that call into BitBake code to read variables, parse recipes, etc. (as used by various scripts in BitBake & OE, including bitbake-layers, devtool, etc.) This patchset reworks tinfoil in order to address several limitations of the current implementation, first and foremost that it doesn't currently work in bitbake's memory resident mode. This rework is also known as "tinfoil2" although the classes and modules have not changed name. This patchset depends upon the corresponding patchset sent to the bitbake-devel list and both sets should be applied together in order for things to remain working.

Note that whilst these patchsets make some significant improvements to how the system behaves in memory resident mode, there are still a number of issues that prevent memory resident mode from being reliable. See this wiki page for a few more details:

I will be converting some of these into bugzilla entries after this patchset and the corresponding one for bitbake get merged.

The following changes since commit d62f18c39bc0ed3b0f5ac8465b393c15f2143ecf:
