67484a90fa GH-211: improve consistency of how scripting errors are handled
Scripting errors/mistakes now consistently generate a runtime error
which have the behavior of unwinding the call stack all the way out of
the current event handler.

Before, such errors were not treated consistently and either aborted
the process entirely or emitted a message while continuing to execute
subsequent statements without well-defined behavior (possibly causing
a cascade of errors).

The previous behavior also would only unwind out of the current
function (if within a function body), not out the current event
handler, which is especially problematic for functions that return
a value: the caller is essentially left a mess with no way to deal
with it.

This also changes the behavior of the startup/initialization process
to abort if there's errors during bro_init() rather than continue one
to the main run loop.  The `allow_init_errors` option may change this
new, default behavior.

005bf5b6a4 Convert site::local_nets, etc. into options.
These are probably some of the most desired options to be dynamically
changeable; since they only are accessed in script-land there should not
be any problems with them changing on the fly.

3919a35b9b Metrics framework update. Mostly to make metrics work on clusters.
- Metrics now work on cluster deployments with no caveats.  It should be
  completely transparent.  Intermediate updates to speed some detection
  will come later.

5f61c9bde9 New variable in utils/site for mapping address to defined local subnet.
- Site::local_nets_table[1.2.3.4] might yield "1.2.0.0/16" if that
  subnet is defined in the Site::local_nets variable.

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.
