- transactions are now bidirectional
- there is a logger
- gap support is improved with probing for resync
- frames support
- app-layer events
- enip_command keyword accepts now string enumeration as values.
- add enip.status keyword
- add keywords :
enip.product_name, enip.protocol_version, enip.revision,
enip.identity_status, enip.state, enip.serial, enip.product_code,
enip.device_type, enip.vendor_id, enip.capabilities,
enip.cip_attribute, enip.cip_class, enip.cip_instance,
enip.cip_status, enip.cip_extendedstatus
Some exception policies can only be applied to entire flows or
individual packets, for some exception scenarios. Make this easier to
read, in the documentation.

Task #5816
One of the lessons of the XZ backdoor story was that just linking to
libsystemd to call sd_notify is discouraged by the systemd project:
Lennart Poettering:
"PSA: In context of the xzpocalypse we now added an example reimplementation
of sd_notify() to our man page:
https://www.freedesktop.org/software/systemd/man/devel/sd_notify.html#Notes
It's pretty comprehensive (i.e. uses it for reload notification too), but
still relatively short.
In the past, I have been telling anyone who wanted to listen that if all you
want is sd_notify() then don't bother linking to libsystemd, since the
protocol is stable and should be considered the API, not our C wrapper
around it. After all, the protocol is so trivial"

This commit takes the example code and uses it to reimplement the notify
logic.
The code is enabled if Linux is detected in configure. Since the code
won't do anything if the NOTIFY_SOCKET env var isn't set, this should
also work fine on systems w/o systemd.
Ticket: #6913.
Remove references that are mentioning Suricata 3 or less
As a note - only one Suricata 4 reference found:
(suricata-yaml.rst:"In 4.1.x")
Fast pattern selection criteria can be internally found by inspecting
SupportFastPatternForSigMatchList and SigTableSetup functions.
Ticket: #6570
If an exception policy wasn't set up individually, use the GetDefault
function to pick one. This will check for the master switch option and
handle 'auto' cases.
Instead of deciding what the auto value should be when we are parsing
the master switch, leave that for when some of the other policies is to
be set via the master switch, when since this can change for specific
exception policies - like for midstream, for instance.
Update exceptions policies documentation to clarify that the default
configuration in IPS when midstream is enabled is `ignore`, not
`drop-flow`.
Bug #6169
DPDK apps can specify multiple arguments of the same
type. YAML format only allows unique keys within a single
node. This commit adds support for multiple EAL arguments
of the same type to be used within suricata.yaml.
Ticket: #5964
Some exception policies can only be applied to the triggering packet or
only make sense considering the whole flow. Highlight such cases in the
table showing each exception policy.

Bug #5825
The different interactions between midstream pick-up sessions and the
exception policy can be quite difficult to visualize. Add a section for
that in the userguide.

This commit adds brief discussion for additional cluster types for use
with the pf-ring packet source.
Newly added:
- cluster_inner_flow
- cluster_inner_flow_2_tuple
- cluster_inner_flow_4_tuple
- cluster_inner_flow_5_tuple
Issue: 5975
As flow.memcap-policy and defrag.memcap-policy do not support flow
actions, clarify that in the documentation. Also fix some typos, and
add missing values in some places where the exception policies were
explained.

Bug #5940
This allows all traffic Exception Policies to be set from one
configuration point. All exception policy options are available in IPS
mode. Bypass, pass and auto (disabled) are also available in iDS mode
Exception Policies set up individually will overwrite this setup for the
given traffic exception.
