wine/test.h: Identify the process responsible for test summary lines. [RFC]

[Francois Gouget]

Currently the child process summary lines are indistinguishable from the
main process one. This makes it impossible to automatically detect
when a process exits abruptly, i.e. without printing a summary line,
if it has run a subprocess.
This patch will let analysis tools identify which summary lines
correspond to processes they started and thus when some are missing.
Note also that in case of a crash the 'unhandled exception' play the
same role as the test summary lines. Thus it is important to also tag
them with the pid of the source process.
