  imapc: Don't send NOOP immediately after SELECT

NOOP is normally used by mailbox syncing to check if there are any changes
done by other concurrent IMAP sessions. But doing it immediately after
SELECT is unnecessary, because nothing could have changed.

  openssl: Clear error queue after an incomplete SSL_shutdown

If the SSL_shutdown-call fails (e.g. because the underlaying socket has
already been closed) OpenSSL puts the corresponding error into the
queue. We don't care about details so we need to clear the queue.

Otherwise the error will be pulled while error checking the next OpenSSL
call of an unrelated connection.

  configure: Fix some implicit function declarations

Some configure tests fail unexpectedly if the compiler flag
-Werror=implicit-function-declarations is enabled, which can result
in the wrong implementations being used.

This compiler flag is now enabled by default in Fedora Rawhide:

<stdlib.h> is needed for exit()
<string.h> is needed for strcpy()
