Directory name for bro core coverage changed to "coverage", error
messages made nicer. Use `make html` in testing/coverage to create
logs in HTML format when lcov exists on the system.
Adds --enable-coverage flag to configure Bro with gcov.
A new directory named /testing/bro-code-coverage/ contains a new
coverage target that as part of `make coverage` in /testing/.
This coverage option creates coverage.log of all important directories in /src/ and
places all generated .gcov files alongside the corresponding source file.
- BRO_PROFILER_FILE now passes .X* templated filenames to mkstemp
for generating unique coverage state files. All test suites
now use this so each Bro instance writes to a unique coverage file.
- Rearranging Makefile targets. The general rule is that if the
all/brief target fails out due to a test failure, then the dependent
coverage target won't run, but can still be invoked directly later.
(e.g. make brief || make coverage)
- 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.
