Frames:
- sip.pdu
- sip.request_line
- sip.response_line
- sip.request_headers
- sip.response_headers
- sip.request_body
- sip.response_body
The `sip.pdu` frame is always created, the rest only if the record
parser succeeded.
Ticket: #5036.
While ReadTheDocs can't execute arbitrary scripts, we can install
mscgen in the container that builds the docs (see .readthedocs.yaml).
Then instead of calling generate-images.sh from the Makefile, move this
into the setup function defined on conf.yaml, which will generate the
scripts as part of a normal Sphinx workflow.
This should give us an image generation solution that works on
ReadTheDocs, and locally within anyones build system provided they have
mscgen installed.

This is not the perfect solution, but it prevents to trigger
the assert, and keep the assert.
A better solution would need to create transaction from
the reponse parsing, in case a later command was buffered and
not answered. But this would not be enough as NoNewTx prevents
the creation of a new transaction for RSET...

As for HTTP2 and MQTT.
In FTP case, transactions are pipelined, not identified by an id.
So, there are less chances of DOS by quadratic complexity.
max-streams and max-table-size
Allows users to find balance between completeness of decoding
and increases resource consumption, which can DOS suricata.
Parse extract-url-schemes from the mime config.
e.g. 'extract-urls-schemes: [http, https, ftp, mailto]'
Update MimeDecConfig struct to new url extraction fields.
Change app-layer-smtp.c & util-decode-mime.c to initialize new struct
fields for MimeDecConfig.
Sets the default value for extract-url-schemes if not found in the
config to 'extract-urls-schemes: [http]' for backwards compatibility.
Uses the schemes defined in the mime config value for
extract-urls-schemes to search for URLS starting with those scheme
names followed by "://".
Logs the URLS with the scheme + '://' at the start if the
log-url-scheme is set in the mime config, otherwise the old behaviour
is reverted to and the urls are logged with the schemes stripped.
Removed unused constant URL_STR now that URLS are being searched for
using extract-urls-schemes mime config values instead of just URL's
starting with 'http://'.
Added commented out new options for extract-urls-schemes and
log-url-scheme to suricata.yaml.in.
Update FindUrlStrings comments.
Remove old outdated comments/commented code from FindUrlStrings.
Update test case for mime which now needs schemes list to be set.
Add Test Cases for FindUrlStrings() method.
