Threads will now reliably get a call to DoFinish() no matter how the
thread terminates. This will always be called from within the thread,
whereas the destructor is called from the main thread after the child
thread has already terminated.
Also removing debugging code.
However, two problems remain with the ASCII writer (seeing them only
on MacOS):
- the #start/#end timestamps contain only dummy values right now.
The odd thing is that once I enable strftime() to print actual
timestamps, I get crashes (even though strftime() is supposed to
be thread-safe).
- occassionally, there's still output missing in tests. In those
cases, the file descriptor apparently goes bad: a write() will
suddently return EBADF for reasons I don't understand yet.
- The Makefiles now run btest with "-f diag.log" so that diangnostics
output will always be written into that file.
- Makefiles now hardcode path to btest to avoid picking up the wrong version
if in PATH.
- The canonifier scripts now live in testing/scripts, and they are
used from both btest/ and external/.
- There's a new diff-remove-uids scripts that removed connection UIDs
for diffing. The external/* tests now use that by default.
- Timestamp removal now has its own script: diff-remove-timestamps.
diff-canonifier calls that.
- All Makefile have a "brief" target that runs btest with -b.
- The higher-level directories have Makefile to call the subdirs.
