[stunnel-users] use somaxconn in stunnel

[Stefan Behte]

Hi,

attached you will find a patch from Thomas Franco to honor SOMAXCONN.
It defaults to 128, which is not enough for some setups. It defines the maximum number of requests that can be queued to a listening socket and can be changed with sysctl via net.core.somaxconn.

I think it would be nice to have it in stunnel-4.36 to make it usable in bigger installations. It's available online here: https://github.com/op4g/stunnel/commit/e200bebaf92c068aa319c43fdd50cddd6816c7a3

Best regards,

Stefan Behte
