It can be handy to get system information from journald to correlate with
what is going on in applications. This simple journald tail GSource will
dispatch to our callback which can append the logs to the capture.
This uses a custom callback rather than the GSourceFunc because that seems
a bit annoying to use with recent GCC function equivalence checks.
The visibility of symbols was getting extracted from the .a into the
libraries that link_whole the archive. We can simply disable the visibility
from the .a with a custom config.h.meson which avoids it for the capture
library. Since we already double-compile those sources for the shared
library, the shared library visibility is not affected.
This was tested by compiling a simple library which calls
sysprof_clock_init() and ensuring that no extra symbols were found with
`nm libfoo.so | grep ' T '`.
Fixes#60
Historically, Sysprof never supported translations. When revamping the
Sysprof implementation we didn't fix that, even though we were able to
start accepting translations.
This ensures we setup the translation tooling at startup.
