PVXS release 0.1.1

[Michael Davidsaver via Tech-talk <tech-talk at aps.anl.gov>]

0.1.1 is the first patch release for the PVXS module.
Which is a new PVAccess protocol client+server library.

This is a bug fix release which addresses an interoperability
issues with the pvAccessJava module (Thanks to karlosp) for
reporting.  Also a couple of more minor issues.

Based an analysis with abi-compliance-checker I believe that the ABI
of the libraries in 0.1.1 remains backward compatible with 0.1.0.  So
it _should_ be possible to update PVXS without rebuilding dependent
code.

ABI compatibility with C++ is still something I'm not certain about.
I would like to hear from anyone who tries this (successfully or
otherwise).

I've attached the report generated by abi-compliance-checker to
the github release.  Also a unit test coverage report from GCOVR.
This is a bit of an experiment.  I'm not certain if I'll continue
to publish these with future releases, so please let me know if
you find them useful.
