ec721dffec Added is_orig fields to the SSL events and adapted script.
- Added a field named $last_alert to the SSL log.  This doesn't even
  indicate the direction the alert was sent, but we need to start somewhere.

- The x509_certificate function has an is_orig field now instead of
  is_server and it's position in the argument list has moved.

- A bit of reorganization and cleanup in the core analyzer.

6d67f7830d Added to the likely_server_ports set for protocols with analyzers.
- Updated some tests since Bro is getting the direction
  correct now.

- Updated BPF filter test since I added a few ports to IRC
  as well.

8710d3749f New SSL policy scripts.
- protocols/ssl/expiring-certs uses time based information from
  certificates to determine if they will expire soon, have already
  expired, or haven't yet become valid.

- protocols/ssl/extract-certs-pem is a script for taking certs off
  the line and converting them to PEM certificates with the openssl
  command line tool then dumping them to a file.

123a3bd4e3 Small rework with ssl base script to reduce memory usage.
- We are now removing the SSL analyzer after logging the session
  infomrtion.  This seems to help a lot with overly high memroy
  consumption.

ee1884ca93 Another change to possibly fix the SSL memory consumption problem.
- If a protocol violation happens, Bro now logs what it has seen
  up until the protocol violation and deletes the c$ssl record
  so that a long lived connection with a protocol violation does
  continue to hold the memory.

c87704cc25 Small usability and correctness updates.
- Removed an notice definition from the base SSL scripts.

- Moved a logging stream ID into the export section for known-services
  and bumped priority for creating the stream.

- Adding configuration knobs for the SQL injection attack detection
  script and renaming the HTTP::SQL_Injection_Attack notice to
  HTTP::SQL_Injection_Attack_Against

- Bumped priority when creating Known::CERTS_LOG.

4931aa815f Delete SSL certificates from memory after ssl_established event.
- This is an attempt at fixing the memory issues brought about by
  the introduction of the new SSL analyzer.  My initial testing
  shows a hefty memory saving.

11c437faa3 Logging framework update and mass Log::ID renaming.
- Log path's are generated in the scripting land
  now.  The default Log stream ID to path string
  mapping works like this:
    - Notice::LOG -> "notice"
    - Notice::POLICY_LOG -> "notice_policy"
    - TestModule::LOG -> "test_module"

- Logging streams updated across all of the shipped
  scripts to be more user friendly.  Instead of
  the logging stream ID HTTP::HTTP, we now have
  HTTP::LOG, etc.

- The priorities on some bro_init handlers have
  been adjusted to make the process of applying
  filters or disabling streams easier for users.

47500ceef4 Add a test that checks each individual script can be loaded in bare-mode.
Fixed most @load dependency issues in the process.  The test is still
failing in a "known" way due to hot.conn.bro and scan.bro.

597a4d6704 Hopefully the last major script reorganization.
- policy/ renamed to scripts/

- By default BROPATH now contains:
	- scripts/
	- scripts/policy
	- scripts/site

- *Nearly* all tests pass.

- All of scripts/base/ is loaded by main.cc
	- Can be disabled by setting $BRO_NO_BASE_SCRIPTS
	- Scripts in scripts/base/ don't use relative path loading to ease use of BRO_NO_BASE_SCRIPTS (to copy and paste that script).

- The scripts in scripts/base/protocols/ only (or soon will only) do logging and state building.

- The scripts in scripts/base/frameworks/ add functionality without causing any additional overhead.

- All "detection" activity happens through scripts in scripts/policy/.

- Communications framework modified temporarily to need an environment variable to actually enable (ENABLE_COMMUNICATION=1)
	- This is so the communications framework can be loaded as part
	  of the base without causing trouble when it's not needed.
	- This will be removed once a resolution to ticket #540 is reached.
