### Description
I am doing some experiments with NGHTTP2 Module to make use of it in some scenarios, where Kamailio receives HTTP2 requests and has t react on them, unfortunately the module is causing Kamailio to crash upon receiving a request and need to be restarted.
Also the Docs for the module need some correction :
https://www.kamailio.org/docs/modules/5.9.x/modules/nghttp2.html
Missing required Parameters :
modparam("nghttp2", "tls_private_key", "key_in_PEM_Format")
modparam("nghttp2", "tls_public_key", "certificate_in_PEM_Format")
also $nghttp2(url) is wrong, $nghttp2(path) or $nghttp2(pathfull) is the correct ones.
its also annoying to have it only working in TLS, would it possible to make it also works without TLS ?
#### Reproduction
the fastest way it to connect to NGHTTP2 server with curl :
curl --http2-prior-knowledge -v -k https://server_ip:port/

### Description
Calling functions from the `dialplan` module in 5.8 (`dp_translate()`, `dp_match()`) results in the following line being logged:
```
WARNING: <core> [core/mem/q_malloc.c:520]: qm_free(): WARNING: free(0) called from dialplan: dp_db.c: pcre2_free(206)
```
Is this a functional problem, or just a case of overly aggressive logging?
### Troubleshooting
#### Reproduction
Reproducible with the following kamailio config:
```
#!KAMAILIO
loadmodule "pv"
loadmodule "db_sqlite"
loadmodule "xlog"
loadmodule "dialplan"
disable_tcp = true
force_rport = true
!!define DBFILE /etc/kamailio/kamailio.sqlite
modparamx("db_sqlite","db_set_readonly", "$def(DBFILE)")
modparamx("dialplan","db_url", "sqlite:///$def(DBFILE)")
modparam("dialplan", "attrs_pvar", "$avp(dp_attrs)")
request_route {
if ( $rm == "ACK" ) {
exit;
}
xinfo("$ci New request\n");
dp_match("1", "$rU");
exit;
}
```
The warning log is issued in 5.8 but not 5.7. Reproduced by sending a request with SIPp:
```
sipp -sn uac -m 1 -s 15554445555 localhost
```
### Possible Solutions
Not sure if this is just a case of logging being overly aggressive, or an issue with the module's memory management.

#### Description
<!-- Describe your changes in detail -->
This PR Fixes a bug where logging shows a truncated command instead of the original one.
Original query in .cfg: `sql_query("ca", "UPDATE dialog SET timeout = timeout + 1 WHERE callid = '$ci' AND timeout > 0;`
logged error before fix:
sql_do_query(): cannot do the query [UPDATE dialog SET timeout = timeout + 1 WHERE callid = 'al@there]
logged error after fix:
sql_do_query(): cannot do the query [UPDATE dialog SET timeout = timeout + 1 WHERE callid = 'al(a)there.com AND timeout > 0;]
