Subject: [PATCH 1/1] Backport Bugfix for 62880 (clear error queue before
 loading CA chains)

This commit backports the fix found at:
https://bz.apache.org/bugzilla/show_bug.cgi?id=62880
and applies it to the 2.4.23 release, to fix bug #1162027 .

Previously, OpenSSL's error queue was only checked after the
certificate chain had loaded, which resulted in this error message:

"AH01903: Failed to configure CA certificate chain!"

This fix clears OpenSSL's error queue before the certificate chain is
loaded, so that there will only be an error message if there is
actually an error when loading the chain.
