Gathers a list of paths to have checksums calculated at parse time, and processes these when calculating task hashes. Checksums are cached with the file's current mtime. Thus, changing any local file in SRC_URI will now cause the do_fetch taskhash to change, thus forcing a rebuild. This change adds very roughly about an 8% increase in parse time (a few seconds) and maybe a few seconds during runqueue generation, so a fairly moderate performance hit. Note that since paths are resolved at parse time, this will not force a rebuild when files are introduced which would cause that resolved path to be different - for example, where a machine-specific version of a file was added without otherwise changing the recipe. This will need to be handled in a future update. Code to hook this into the signature generator was courtesy of Richard Purdie <richard.purdie@linuxfoundation.org>. Implements [YOCTO #2044].

README
Poky ==== Poky is an integration of various components to form a complete prepackaged build system and development environment. It features support for building customised embedded device style images. There are reference demo images featuring a X11/Matchbox/GTK themed UI called Sato. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK with IDE integration. Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of layers which extend the systems capabilities in a modular way. As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information e.g. for the hardware support. Poky is in turn a component of the Yocto Project. The Yocto Project has extensive documentation about the system including a reference manual which can be found at: http://yoctoproject.org/community/documentation OpenEmbedded-Core is a layer containing the core metadata for current versions of OpenEmbedded. It is distro-less (can build a functional image with DISTRO = "") and contains only emulated machine support. For information about OpenEmbedded, see the OpenEmbedded website: http://www.openembedded.org/
