63c36d58f3 Another attempt to improve core.when-interpreter-exceptions unit test.
lookup_hostname("localhost") occassionally timed out (after allowed 10
secs) when running test suite on some systems.  Not sure why, but
changed to use the Exec module for when block conditions instead as the
scope of the test doesn't depend on a particular type of condition, it
just needs something that will work reliably/quickly.

Shouldn't cause a problem as it's always set in subclass ctors,
just silences a coverity warning.

dedc39d784 Minor Broxygen improvements, addresses BIT-1098.
- Internals: move type alias table to private static BroType member.

- Sphinx extension: now uses absolute path to bro binary.

- reST ouput formatting: remove "param" from function desriptions
  and change package overview docs so script link+summaries render
  consistently.

3c59aa9459 Several fixes for input manager error handling.
- First:
Due to architectural constraints, it is very hard for the
input framework to handle optional records. For an optional record,
either the whole record has to be missing, or all non-optional elements
of the record have to be defined. This information is not available
to input readers after the records have been unrolled into the threading
types.

Behavior so far was to treat optional records like they are non-optional,
without warning. The patch changes this behavior to emit an error on stream-
creation (during type-checking) and refusing to open the file. I think this
is a better idea - the behavior so far was undocumented and unintuitive.

- Second:
For table and event streams, reader backend creation was done very early,
before actually checking if all arguments are valid. Initialization is moved
after the checks now - this makes a number of delete statements unnecessary.
Also - I suspect threads of failed input reader instances were not deleted
until shutdown

- Third:
Add a couple more consistency checks, e.g. checking if the destination value
of a table has the same type as we need. We did not check everything in all
instances, instead we just assigned the things without caring (which works,
but is not really desirable).

This change also exposed a few bugs in other testcases where table definitions
were wrong (did not respect $want_record)

- Fourth:
Improve error messages and write testcases for all error messages (I think).

504d22b91b fix memory leak in input framework.
If the input framework was used to read event streams and
those streams contained records with more than one field, not all
elements of the threading Values were cleaned up.

The reason for this is, that the SendEventStreamEvent function
returned the number of record elements in the outmost record
instead of the number of unrolled elements in the whole vector.

This number is later used to determine how many objects to delete.

Also - add a whole bunch of leak checks for the input framework
that would have caught that and should cover quite a number of
use-cases.

8515d3aa57 Support omission of string slice low/high indices, BIT-1097.
Omission of the low index defaults to 0:

    s = "12345"; s[:3] == "123"

Omission of the high index defaults to length of the string:

    s = "12345"; s[3:] == "45"

dadfcde70e Merge branch 'topic/robin/event-dumper'
Changes:

   - Changing semantics of the new_event() meta event: it's raised
     only for events that have a handler defined. There are too many
     checks in Bro that prevent events wo/ handler from being even
     prepared to raise to do that differently.

   - Adding test case.

* topic/robin/event-dumper:
  New script misc/dump-events.bro, along with core support, that dumps events Bro is raising in an easily readable form.
  Prettyfing Describe() for record types.

2ea6011186 Improve a unit test involving 'when' conditionals.
May fix a sporadic failure, in which case it was just not getting enough
time to run or lookup_hostname() taking longer than ~3 seconds.  Else,
the new output should give more hints on what's going wrong.  In any
case, termination conditions for the test are now explicit.

4014cdc277 Fix string slice notation, addresses BIT-1097.
Slice ranges were not correctly determined for negative indices and also
off by one in general (included one more element at the end of the
substring than what actually matched the index range).

It's now equivalent to Python slice notation.  Accessing a string at
a single index is also the same as Python except that an out-of-range
index returns an empty string instead of throwing an expection.

5aa04089af Unit test for broccoli vector support.
Broccoli clients can only recv events w/ vectors for now.

Also changed ordering of Bro type tag enum -- the addition of opaque
types changed the value of the vector type, making broccoli.h's
definition out of sync.  Probably could have just changed broccoli's
definition, but seems more correct to go back to using the same value
for vectors as they were before opaques.  It's also better in case
there's some other location I'm not aware of where the values are
replicated.

7e0864468c A couple documentation fixes.
- Move notice index wrapper doc to doc/script-reference -- doc/scripts
  no longer contains any static documentation because that location
  will be managed by Bro to generate per-script docs.

- :doc: references for generated per-script docs now need the ".bro"
  suffix.  (IMO this is better since it directly mirrors the actual
  script's file name and can't be confused w/ a package).

9967aea52c Integrate new Broxygen functionality into Sphinx.
Add a "broxygen" domain Sphinx extension w/ directives to allow
on-the-fly documentation to be generated w/ Bro and included in files.

This means all autogenerated reST docs are now done by Bro.  The odd
CMake/Python glue scipts which used to generate some portions are now
gone.  Bro and the Sphinx extension handle checking for outdated docs
themselves.

Parallel builds of `make doc` target should now work (mostly because
I don't think there's any tasks that can be done in parallel anymore).

Overall, this seems to simplify things and make the Broxygen-generated
portions of the documentation visible/traceable from the main Sphinx
source tree.  The one odd thing still is that per-script documentation
is rsync'd in to a shadow copy of the Sphinx source tree within the
build dir.  This is less elegant than using the new broxygen extension
to make per-script docs, but rsync is faster and simpler.  Simpler as in
less code because it seems like, in the best case, I'd need to write a
custom Sphinx Builder to be able to get that to even work.
