BUG/MEDIUM: ssl: Verify error codes can exceed 63

The CRT and CA verify error codes were stored in 6 bits each in the
xprt_st field of the ssl_sock_ctx meaning that only error code up to 63
could be stored. Likewise, the ca-ignore-err and crt-ignore-err options
relied on two unsigned long longs that were used as bitfields for all
the ignored error codes. On the latest OpenSSL1.1.1 and with OpenSSLv3
and newer, verify errors have exceeded this value so these two storages
must be increased. The error codes will now be stored on 7 bits each and
the ignore-err bitfields are replaced by a big enough array and
dedicated bit get and set functions.

It can be backported on all stable branches.

[wla: let it be tested a little while before backport]
