9bb1d13afa Revert to non-shared mutex for data lock.
The main change here is that the UI will be unresponsive when a trace is being
saved when there's no capture being performed. Note that the UI was always
frozen during saving if the capture was live, due to how starvation is
prevented by the locks.

0f13a02062 Properly terminate symbol inline location data.
Previously there was no end value on which iteration would stop in case of
the last-in-the-process-space symbol, which resulted in out-of-bounds read.

Workaround has been added for versions < 0.7.2, but no version bump has been
performed (still at 0.7.1). Having two terminator values at the end of the
list is harmless.
