2f27523e44 bufferevent_ssl: do not return NULL from upcast 
/src/le/libevent/bufferevent_ssl.c:863: error: Null Dereference
      pointer `bev_ssl` last assigned on line 855 could be null and is dereferenced at line 863, column 6.
      861.          r2 = start_writing(bev_ssl);
      862.
      863.  if (bev_ssl->underlying) {

e5941b2ce9 Drop unused le_ssl_ops::err_is_ok 
It is not used anymore since errors are ignored if some progress had
been done.

7652cf4068 ssl: do not triger EOF if some data had been successfully read 
Previously in case when evbuffer_reserve_space() returns > 1, but
it was able to read only 1 IO vector, it will try to read the next one,
got 0 (EOF for mbedTLS or SSL_ERROR_ZERO_RETURN for OpenSSL) and will
trigger EOF, while instead, it should trigger EV_READ w/o EOF and only
after EOF.

384c52e6be Initial Mbed-TLS 3 support to get the GitHub Actions working again 
mingw has upgraded to Mbed-TLS 3.1.0, so all the mingw tests that need
Mbed-TLS currently don't work.

v2: add missing mbedtls/version.h into test/regress_mbedtls.c
v3: suppress #warning "Including compat-2.x.h is deprecated" for mbedtls/compat-2.x.h

7e0fc878c5 Introduce new API for flags of the SSL bufferevent 
Introduce more generic API (like for evbuffer):
- bufferevent_ssl_set_flags()
- bufferevent_ssl_clear_flags()
- bufferevent_ssl_get_flags()

And deprecate existing:
- bufferevent_openssl_get_allow_dirty_shutdown()
- bufferevent_openssl_set_allow_dirty_shutdown()
- bufferevent_mbedtls_get_allow_dirty_shutdown()
- bufferevent_mbedtls_set_allow_dirty_shutdown()

948ad30435 Fix bufferevent_get_{openssl,mbedtls}_error() 
The bufferevent_get_openssl_error() returns unsigned long, so returning
-1 on error in unclear. Let's use 0.

Fixes: #1028

d095b834a9 Merge ssl implementations (openssl and mbedtls) 
This patch splits common part out to avoid copy-paste from the
- bufferevent_openssl.c
- bufferevent_mbedtls.c

It uses VFS/bufferevent-like approach, i.e. structure of callbacks.
