Changelog for 1.3

[Paul Eggleton <paul.eggleton@linux.intel.com>]

Hi folks,

I've put together a list of medium to high-level changes based on
browsing through the commits for the release:

- Improved terminal UI which makes it easy to see the tasks that are currently executing, and avoids burying any warnings that are printed
- Eliminated intermediate step when building cross compiler toolchain
- SDK is now relocatable
- Large number of usability improvements in the Hob image building UI
- Upgraded eglibc to version 2.16
- Upgraded gcc to version 4.7
- Added yocto-bsp script for automating the initial parts of creating a new BSP
- Python functions now consistently use four spaces for indentation - no more having to try to match the mix of tabs and spaces in your recipes
- Disabled sharing shared state between machines using different distros by default to avoid glibc version problems
- Fixes to allow qemu-native to be built on host systems without X11 (i.e. for console use only)
- Enabled python and perl scripting for perf as well as text-mode UI
- Added ability to produce a companion SDK together with an image
- Allow forcing the rebuilding of a recipe (new -C and improved -f options)
- Enabled EFI in grub installer
- Mesa can now provide GLES accelerated graphics without X11
- Added script for producing "bootcharts" from buildstats so you can see the timeline of the build
- Checksums for local files referred to in SRC_URI are now included in task signatures so that changing their contents causes the relevant tasks to be re-executed
- Extended bitbake-diffsigs to look up signature files from task and recipe name, and trace back recursively through dependent task changes
- Moved from module-init-tools to kmod
- Added create-recipe script to automate some of the parts of creating a brand new recipe
- Buildhistory improvements: better performance, track postinst/postrm scripts
- Added bin_package bbclass for recipes that package pre-built binaries
- Added doc-pkgs IMAGE_FEATURES feature to install all documentation
- Added class-* overrides - particularly useful for target/cross/crosssdk but works with all classes
- Reference hardware BSPs are now separate from Poky reference distro configuration
- nativesdk is now a prefix rather than a suffix, simplifying packaging in nativesdk recipes greatly
- Detect and warn if files in the sysroot are potentially written to by multiple recipes
- Automatic launching of "screen" within terminal for devshell/patch resolution
- task-* recipes renamed to packagegroup-* and tidied up significantly
- Improved mirror handling - allow mirrors of mirrors; handle errors more gracefully
- Reduced dependencies between debugging symbol packages
- Significant cleanup of X server recipes
- Start to add regression tests for BitBake

Is there anything that belongs here that I have missed? I know we've done a
lot of other bugfixes and package upgrades, we're really after the
highlights.

Cheers,
Paul
