[Proposal] Make ngx_stream module an optional feature

[dedok]

Description

We don't use ngx_stream module in the production and we do not have it in the compilation. As I know not all user's of nginx using --with-stream module. If try to compile this module w/o --with-stream, error appears.

Proposal

Enable compilation of ngx_stream_ssl_fingerprint_preread_module.c iff nginx's internal flag which set by Nginx's configure is present, else do not build ngx_stream_ssl_fingerprint_preread_module.c at all.

[phuslu]

Yes, that's right, providing an optional ngx_stream will make this module more comprehensive.

This is done in: https://github.com/phuslu/nginx-ssl-fingerprint/tree/fix-ssl-extentions-for-openssl-3-4
But need a ~1 day to done with testing.
