Instead of having an additional string argument specifying if we are
sending a request or a reply, we now have an ANALYZER_OCSP_REQUEST and
an ANALYZER_OCSP_REPLY
Instead of having a big event, that tries to parse all the data into a
huge datastructure, we do the more common thing and use a series of
smaller events to parse requests and responses.
The new events are:
ocsp_request -> raised for an ocsp request, giving version and requestor
ocsp_request_certificate -> raised n times per request, once per cert
ocsp_response_status -> raised for each ocsp response, giving status
ocsp_response_bytes -> raised for each ocsp response with information
ocsp_response_certificate -> raised for each cert in an ocsp response
- New fields: extracted_cutoff and extracted_size.
These fields will be null if the file isn't extracted.
- Extended the extraction test to test the files log too.

Lots of fixes for file type identification.
BIT-1368 #merged
This allows the path for the default filter to be specified explicitly
when creating a stream and reduces the need to rely on the default path
function to magically supply the path.
The default path function is now only used if, when a filter is added to
a stream, it has neither a path nor a path function already.
Adapted the existing Log::create_stream calls to explicitly specify a
path value.
Addresses BIT-1324
- Plain text now identified with BOMs for UTF8,16,32
(even though 16 and 32 wouldn't get identified as plain text, oh-well)
- X.509 certificates are now populating files.log with
the mime type application/pkix-cert.
- File signatures are split apart into file types
to help group and organize signatures a bit better.
- Normalized some FILE_ANALYSIS debug messages.
- Improved Javascript detection.
- Improved HTML detection.
- Removed a bunch of bad signatures.
- Merged a bunch of signatures that ultimately detected
the same mime type.
- Added detection for MS LNK files.
- Added detection for cross-domain-policy XML files.
- Added detection for SOAP envelopes.
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.
Retrieval of extended alert information from sid-msg.map, gen-msg.map,
and classification.config files uses Bro's input framework, but since
the unified2 file analyzer also relies on the input framework,
coordination is needed to start analysis only after extended info has
been read at least once.
