[ClusterLabs] [Announce] libqb 10.rc4 release

[Christine Caulfield]

This is a bugfix release and a potential 1.0 candidate.

There are no actual code changes in this release, most of the patches
are to the build system. Thanks to Jan Pokorný for, er, all of them.
I've bumped the library soname to 0.18.0 which should really have
happened last time.

Changes from 1.0rc3

    build: fix tests/_syslog_override.h not being distributed
    build: enable syslog tests when configuring in spec
    build: do not install syslog_override for the RPM packaging
    build: update library soname to 0.18.0
    build: do not try to second-guess "distdir" Automake variable
    build: switch to XZ tarball format for {,s}rpm packaging
    CI: make sure RPM can be built all the time
    Generating the man pages definitely doesn't depend on existence of
(possibly generated) header files that we omit anyway.

    build: extra clean-local rule instead of overriding clean-generic
    build: docs: {dependent -> public}_headers + more robust obtaining

    docs: apply "doxygen -u" on {html,man}.dox.in, fix deprecations

    docs: {html,man}.dox.in: unify where reasonable
