Allow to use recorder library. See https://github.com/c3d/recorder for
details.
The main usage will be to collect statistics while the programs will run.
By default the recorder will be disabled at compile time. The idea of the
usage in SPICE is to collect data while the program run. Using current
SPICE logging facility was discussed but not easy to filter data. Other
solutions (SystemTap, LTTng) were discarded due to not cross platform.
A printf based solution was discussed too but missing the additional tools
which are useful. Currently we don't plan to use as extensively as to be a
problem to be replaced or removed in the future.
Both Autoconf and Meson build systems are supported.
Autoconf requires the addition of SPICE_CHECK_RECORDER call in configure.ac.
Meson requires to add recorder option.
