Subject: [PATCH] [mod_wolfssl] add complex preproc logic for SNI
add complex preproc logic for SNI detection
- HAVE_SNI is not sufficient
- HAVE_LIGHTY is not sufficient (in wolfssl <= 4.5.0)
Instead, use more complex logic wrapping calls to SNI_Callback()
in wolfssl.
x-ref:
"[lighttpd] -mod-wolfssl inhibited by missing library functionality"
https://github.com/openwrt/packages/issues/14142
"put all SNI code behind simpler preprocessor directive HAVE_SNI"
https://github.com/wolfSSL/wolfssl/pull/3538
