Andreas Färber 36ac86c950 Accepting request 487699 from home:bfrogers:branches:Virtualization
Update to rc4 of v2.9.0. Also includes a few other fixes, and a number of tweaks to the spec files. I'd be happy to answer any questions about all those spec file changes, I believe they were all in the direction of a more correct and maintainable spec file. Since this is still in rc phase, let's keep it in devel project. Final release should appear in time for Beta2 of SLE12SP3. Delta from previous: Added Alex's patch for keyboard empty event.

Subject: [PATCH] string-input-visitor: Fix uint64 parsing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
All integers would get parsed by strtoll(), not handling the case of
UINT64 properties with the most significient bit set.
Implement a .type_uint64 visitor callback, reusing the existing
parse_str() code through a new argument, using strtoull().
As this is a bug fix, it intentionally ignores checkpatch warnings to
prefer the use of qemu_strto[u]ll() over strto[u]ll().
