[ANNOUNCE] EFI Boot Guard 0.2 released

[Jan Kiszka]

This is the second release of EFI Boot Guard. A lot of things happened
since the first (unannounced) version 0.1, most notably:

- support for user-defined variables
- consolidated state into single ustate variable
- reworked API
- rework of internal test suite, addressing build system integration,
license compliance and coverage aspects
- added Intel Wildcat LP (PCH9) to iTCO driver
- Travis CI and Coverity Scan integration
- 56 files changed, 4424 insertions(+), 2432 deletions(-)

Thanks to all contributors, specifically Andreas who did most of this work!
