configure: let --enable-debug set -Wenum-conversion with gcc >= 10

Unfortunately, this option is not detecting the same issues as clang's
-Wassign-enum flag, but should still be useful to detect future
mistakes.

openssl: consider ALERT_CERTIFICATE_EXPIRED a failed verification

If the error reason from the lib is
SSL_R_SSLV3_ALERT_CERTIFICATE_EXPIRED, libcurl will return
CURLE_PEER_FAILED_VER

openssl: consider ALERT_CERTIFICATE_EXPIRED a failed verification

If the error reason from the lib is
SSL_R_SSLV3_ALERT_CERTIFICATE_EXPIRED, libcurl will return
CURLE_PEER_FAILED_VERIFICATION and not CURLE_SSL_CONNECT_ERROR.

This unifies the libcurl return code and makes libressl run test 313
(CRL testing) fine.

altsvc: clone setting in curl_easy_duphandle

The cache content is not duplicated, like other caches, but the setting

altsvc: clone setting in curl_easy_duphandle

The cache content is not duplicated, like other caches, but the setting
and specified file name are.

Test 1908 is extended to verify this somewhat. Since the duplicated
handle gets the same file name, the test unfortunately overwrites the
same file twice (with different contents) which makes it hard to check
automatically.

test1541: remove since it is a known bug

A shared connection cache is not thread-safe is a known issue. Stop
testing this until we believe this issue is addressed. Reduces
occasional test failures we don't care about.

The test code in lib1541.c is left in git to allow us to restore it when
we get to fix this.

curl: retry delays in parallel mode no longer sleeps blocking

The previous sleep for retries would block all other concurrent
transfers. Starting now, the retry will instead be properly marked to
not get restarted until after the delay time but other transfers can
still continue in the mean time.
