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.

499ed5b566 Remove the -K/-J options for setting keys.
The options were never really used and do not seem especially useful;
initialization with a seed file still works.

c625128e4e Add test checking the quality of HLL by adding a lot of elements.
The test adds 170,000 IP addresses. After the recent hashing changes,
HLL estimates 171,250 entries (completely stable). Before, HLL estimated,
depending on the initial seeds, ~700 to 300,000 entries.

Added a new BIF haversine_distance that computes distance between two
geographic locations.

Added a new Bro script function haversine_distance_ip that does the same
but takes two IP addresses instead of latitude/longitude.  This function
requires that Bro be built with libgeoip.

a6cb85d86a Add filter_subnet_table bif
This bif works similar to the matching_subnet bif. The difference is
that, instead of returning a vector of the subnets that match, we return
a filtered view of the original set/table only containing the changed
subnets.

This commit also fixes a small bug in TableVal::UpdateTimestamp
(ReadOperation only has to be called when LoggingAccess() is true).

562e5a9f63 Add bif that allows searching for all matching subnets in table.
Example:

global test: set[subnet] = {
	10.0.0.0/8,
	10.1.0.0/16,
	10.2.0.0/16,
	10.2.0.2/31
}

print matching_subnets(10.2.0.2/32, test);
->
[10.2.0.2/31, 10.2.0.0/16, 10.0.0.0/8]

551a7d7394 Make join_string_vec work with vectors containing empty elements.
Without this patch, this scenario results in a segmentation fault.

I opted to keep the separator present for non-existing elements. Hence,
a vector a, [empty], b with separator "|" will result in
a||b

* 'topic/jgras/base64-logging' of https://github.com/J-Gras/bro:
  Update calls of Base64 functions.
  Refactoring of Base64 functions.

I've removed the additional bif for encoding with a connection, as I'm
not sure there's much of a use case for it; we can always add it back
later if it turns out there is. I've also renamed
decode_base64_intern() to decode_base64_conn() to be a bit more
explicit about the difference.

8f3ded5e2d Refactoring of Base64 functions.
Base64Converter now uses a connection directly, instead of an analyzer
redirecting to the underlying connection for reporting to Weird. The new
built-in functions en-/decode_base64_intern make use of this to send
encoding-errors to Weird instead of Reporter.

According to the documentation, using the empty string as alphabet in
the built-in functions, will use the default alphabet. Therefore the
built-in functions can now use default arguments and
en-/decode_base64_custom is deprecated.

The tests have been updated accordingly.

This also patches a few tests to contain certificates that were removed.

CAs in them are no longer valid and it does not really make sense to
update them on each change...

23f04835c6 Deprecate split* family of BIFs.
These functions are now deprecated in favor of alternative versions that
return a vector of strings rather than a table of strings.

Deprecated functions:

- split: use split_string instead.
- split1: use split_string1 instead.
- split_all: use split_string_all instead.
- split_n: use split_string_n instead.
- cat_string_array: see join_string_vec instead.
- cat_string_array_n: see join_string_vec instead.
- join_string_array: see join_string_vec instead.
- sort_string_array: use sort instead instead.
- find_ip_addresses: use extract_ip_addresses instead.

Changed functions:

- has_valid_octets: uses a string_vec parameter instead of string_array.

Addresses BIT-924, BIT-757.

b22ca5d0a3 Replace libmagic w/ Bro signatures for file MIME type identification.
Notable changes:

- libmagic is no longer used at all.  All MIME type detection is
  done through new Bro signatures, and there's no longer a means to get
  verbose file type descriptions (e.g. "PNG image data, 1435 x 170").
  The majority of the default file magic signatures are derived
  from the default magic database of libmagic ~5.17.

- File magic signatures consist of two new constructs in the
  signature rule parsing grammar: "file-magic" gives a regular
  expression to match against, and "file-mime" gives the MIME type
  string of content that matches the magic and an optional strength
  value for the match.

- Modified signature/rule syntax for identifiers: they can no longer
  start with a '-', which made for ambiguous syntax when doing negative
  strength values in "file-mime".  Also brought syntax for Bro script
  identifiers in line with reality (they can't start with numbers or
  include '-' at all).

- A new Built-In Function, "file_magic", can be used to get all
  file magic matches and their corresponding strength against a given
  chunk of data

- The second parameter of the "identify_data" Built-In Function
  can no longer be used to get verbose file type descriptions, though it
  can still be used to get the strongest matching file magic signature.

- The "file_transferred" event's "descr" parameter no longer
  contains verbose file type descriptions.

- The BROMAGIC environment variable no longer changes any behavior
  in Bro as magic databases are no longer used/installed.

- Reverted back to minimum requirement of CMake 2.6.3 from 2.8.0
  (it's back to being the same requirement as the Bro v2.2 release).
  The bump was to accomodate building libmagic as an external project,
  which is no longer needed.

Addresses BIT-1143.

b3bd509b3f Allow iterating over bif functions with result type vector of any.
This changes the internal type that is used to signal that a vector
is unspecified from any to void.

I tried to verify that the behavior of Bro is still the same. After
a lot of playing around, I think everything still should worl as before.

However, it might be good for someone to take a look at this.
