26bf99c5a3 Add parsing for GTPv1 extension headers and control messages.
Added a generic gtpv1_message event generated for any GTP message type.

Added specific events for the create/update/delete PDP context
request/response messages.

Addresses #934.

ad9e2a143c Update software version parsing and comparison to account for a third numeric subversion.
- $addl is also compared numerically now if the value is actually numeric.

69afc4a882 Add an error for record coercions that would orphan a field.
These cases should be avoidable by fixing scripts where they occur and
they can also help catch typos that would lead to unintentional runtime
behavior.

Adding this already revealed several scripts where a field in an inlined
record was never removed after a code refactor.

762c034ec2 Merge remote-tracking branch 'origin/topic/bernhard/input-logging-commmon-functions'
* origin/topic/bernhard/input-logging-commmon-functions:
  add the last of Robins suggestions (separate info-struct for constructors).
  port memory leak fix from master
  harmonize function naming
  move AsciiInputOutput over to threading
  and thinking about it, ascii-io doesn't need the separator
  change constructors
  and factor stuff out the input framework too.
  factor out ascii input/output.
  std::string accessors to escape_sequence functionality
  intermediate commit - it has been over a month since I touched this...

I cleaned up the AsciiInputOutput class somewhat, including renaming
it to AsciiFormatter, renaming some of its methods, and turning the
static methods into members for consistency.

Closes #929.

fdd11428c1 Change reporter messages to more reliably print to stderr.
Moved this functionality to be internal instead of in the script-layer
event handlers.  The issue with the later is that bad things can happen
between the time a reporter event handler is dispatched and the time it
is executed, and if bro crashes in that time, the message may never be
seen/logged.

Addressed #930 (and revisits #836).

0fcc3db9a0 start adding a different text for empty records for the sqlite writer.
Sadly there also seems to be another deadlock issue which I am currently
not really able to figure out - on shutdown sometimes (too often) the main
thread + all sqlite threads wait for semaphores or mutexes.

390e4082c7 Add prototype file analysis interfaces.
Nothing connects to them yet and nothing would happen even if it did.
Work on analyzers/actions for files coming soon.

720089c03f Add a feature to better select the value threshold will apply to in the metrics framework.
- The feature was primarily added to allow the value to be
   modified for cluster based intermediate threshold checks
   without requiring the user to write the metrics filter
   differently for cluster consideration.  It's also a nice
   way to calculate some related information to the metric
   without accidently applying thresholds to that value.

 - Fixed a few small bugs in ftp detect-bruteforcing script
   and adapted it to the new threshold value selection feature.

c3a6916572 More cluster tuning for the metrics framework.
- Fixed several state maintenance issues for intermediate updates.

 - Added a new tuning variable Metrics::max_outstanding_global_views
   which limits the number of in-flight intermediate updates per
   metric filter.

 - Changed the default global view threshold percent to 20% (up from 10%)

50827d8df0 Implement an option to disable intermediate updates for the metrics framework.
- There are some large sites having trouble and I'm thinking it
   might be overload from intermediate updates.

69b7ce12d2 API updates for metrics framework.
- Removed default logging.  Now a function is available for the new
  $period_finished filter field to get the same behavior for logging
  named Metrics::write_log.

- Added index rollups for getting multiple metrics result values
  as the same time.

290c2a0b4d Make const variables actually constant. Addresses #922.
Both local and global variables declared with "const" could be modified,
but now expressions that would modify them should generate an error
message at parse-time.

501328d61a factor out ascii input/output.
First step - factored out everything the logging classes
use ( so only output ).

Moved the script-level configuration to logging/main,
and made the individual writers just refer to it -
no idea if this is good design. It works. But I am happy
about opinions :)

Next step - add support for input...

a5e237f50c The ASCII writer now supports a filter config option
'only_single_header_row' that turns the output into CSV format.

In that mode all meta data is skipped except for a single header line
with the fields names. Example:

    local my_filter: Log::Filter = [$name = "my-filter", $writer = Log::WRITER_ASCII, $config = table(["only_single_header_row"] = "T")];

9edbf3e53c Add GPRS Tunnelling Protocol (GTPv1) decapsulation.
This currently supports automatic decapsulation of GTP-U packets on
UDP port 2152.

The GTPv1 headers for such tunnels can be inspected by handling the
"gtpv1_g_pdu_packet" event, which has a parameter of type "gtpv1_hdr".

Analyzer and test cases are derived from submissions by Carsten Langer.

Addresses #690.
