The CURLOPT_SSL_EC_CURVES option (used by the '--curves' flag) in
libcurl was ignored when compiling with BoringSSL because
HAVE_SSL_CTX_SET_EC_CURVES was explicitly disabled if BoringSSL was
detected. However, this feature is supported in BoringSSL since
5fd1807d. This commit enables it, and also reduces the required minimal
OpenSSL version to 1.0.2 as per OpenSSL's official documentation.
Fixes#8553Closes#8556
The 'oldlibssh' feature indicates that the error code returned by libssh
for a broken known_hosts file should be 67 rather than 60 (test1459).
This feature was added as part of #8444 with 'oldlibssh' mapping to
libssh versions prior to 0.9.6, and then refined as part of #8511 to map
to versions prior to 0.9.5.
In Red Hat Enterprise Linux 8.5 there is a patched version of libssh
version 0.9.4 (https://git.centos.org/rpms/libssh/blob/c8/f/SOURCES) in
which test1459 fails because it returns the "new" value rather than the
"old" one. It's plausible that one of the patches is responsible for
this rather than the underlying code but I don't think so.
This change therefore drops the 'oldlibssh' version check to map to
libssh versions older than 0.9.4, which fixes builds on RHEL-8.
Closes#8548
When built without DNS-over-HTTP and without asynchronous resolvers,
neither the dns nor the data parameters are used.
That is Curl_resolv_check appears to call
Curl_resolver_is_resolved(data, dns). But,
with CURL_DISABLE_DOH without CURLRES_ASYNCH, the call is actually
elided via a macro definition.
This fix resolves the resultant: "unused parameter 'data'" error.
Closes#8505
Ideally, Curl_ssl_getsessionid should not be called unless sessionid
caching is enabled. There is a debug assertion in the function to help
ensure that. Therefore, the pattern in all vtls is basically:
if(primary.sessionid) {lock(); Curl_ssl_getsessionid(...); unlock();}
There was one instance in openssl.c where sessionid was not checked
beforehand and this change fixes that.
Prior to this change an assertion would occur in openssl debug builds
during connection stage if session caching was disabled.

Several years ago a change was made to block user callbacks from calling
back into the API when not supported (recursive calls). One of the calls
blocked was curl_multi_assign. Recently the blocking was extended to the
multi interface API, however curl_multi_assign may need to be called
from within those user callbacks (eg CURLMOPT_SOCKETFUNCTION).
I can't think of any callback where it would be unsafe to call
curl_multi_assign so I removed the restriction entirely.
