Update the way we control the construction of filesystems

As part of the work for the Yocto Project bug # 4079, we need a way to exclude various packages from being installed into the image. There are three mechanisms in place after these patches BAD_RECOMMENDATIONS, NO_RECOMMENDATIONS, and PACKAGE_EXCLUDE>

There was an existing mechanism called "BAD_RECOMMENDATIONS" that has previous been extended for rpm(smart). Debian(apt-get) does not appear to be capable of BAD_RECOMEMNDATIONS, so a warning was added that it will be ignored.

NO_RECOMMENDATIONS allows for the package manager to completely ignore recommended packages during install. This has a side effect of NOT installing kernel modules in many cases, as the kernel modules are listed as recommended packages. If the user uses NO_RECOMMENDATIONS, they are responsible for adding packages to the IMAGE_INSTALL as needed. (Works in all three package types.)

PACKAGE_EXCLUDE is a mechanism for preventing packages from being installed at all. If the package is in the PACKAGE_INSTALL or PACKAGE_INSTALL_ATTEMPTONLY it will be filtered out, and a warning issued. During filesystem construction if a required package was excluded an error will be generated explaining to the end user the image couldn't be generated and which package had the dependency on the excluded component. (Works in all three package types.)

The patches are available at:
