### Description
OpenSSL integration update was back-ported to 5.7 fixing tls and outbound.
The commonly used modules db_mysql, db_unixodbc, db_postgres - fixed on master - did not receive thread-local fixes in time for 5.7.4.
Kamailio configurations with tls +(database module) may see shm errors
Some database modules are observed to initialise OpenSSL even if the actual db connections are in clear.
### Troubleshooting
- run the main kamailio process under gdb. - set breakpoint on CRYPTO_THREAD_set_local (an OpenSSL internal thread-local function) - observe if any calls happen in Thread#1—this is the failure case
### Workaround
When combining tls + database module switch to tls_wolfssl instead
Closed #3738 as completed.
