Funciton ldap_tx_get_responses_dn returns empty buffer in case
the response doesn't contain the distinguished name field
Fixes: 73ae6e997f ("detect: add ldap.responses.dn")
Change variable name 'req' to 'resp' in function ldap_tx_get_responses_dn and documentation nits

Move the configuration file handling to Rust.
These changes will no longer terminate Suricata when there's an invalid
value for ftp.memcap. Like earlier Suricata releases, an error message
is logged "Invalid value <value> for ftp.memcap" but Suricata will no
longer terminate execution. It will use a default value of "0" instead.

If a Suricata inline IPS device is routing traffic over a
non-encrypted tunnel, like IPv6 tunnels, packets in a flow
will be dropped and not be matched. e.g.
The following example is a Suricata inline IPS with an IPv6 tunnel:
request: IPv4]ICMP] -> |IPS| -> IPv6]IPv4]ICMP]
reply: <- |IPS| <- IPv6]IPv4]ICMP]
Both the IPv4 request and IPv6 reply will be seen by Suricata on
ingress. The flows will not be matched due to flow recursion level.
Optionally use pkt recursion level in flow hash. Excluding recursion
level in flow hash allows matching of packet flows and defrag on an
inline IPS Suricata scenario where the IPS device is a tunnel
terminator.

Describe how to use the git commit template. The template helps ensure
that the information needed for evaluation and context is included in
the commit message.

Uses a config parameter detect.guess-applayer-tx to enable
this behavior (off by default)
This feature is requested for use cases with signatures not
using app-layer keywords but still targetting application
layer transactions, such as pass/drop rule combination,
or lua usage.
This overrides the previous behavior of checking if the signature
has a content match, by checking if there is only one live
transaction, in addition to the config parameter being set.
Similar keywords use `isnotset`, while `flowint` only accepted `notset`
Opted to change the code, not only the regex, to keep the underlying
code also following the same patterns.
Task #7426
For example, "requires: foo bar" is an unknown requirement, however
its not tracked, nor an error as it follows the syntax. Instead,
record these unknown keywords, and fail the requirements check if any
are present.
A future version of Suricata may have new requires keywords, for
example a check for keywords.

It takes an argument to match only if the buffer is absent,
or it can still match if the buffer is present, but we test
the absence of some content.
For multi buffers, absent matches if there are 0 buffers.
For file keywords, absent matches if there is no file.
