Changes compared to MeTA1 1.1.Alpha14.1

2020-06-19 Rejecting the envelope sender via a pmilter did not work if delay_checks was enabled.
2020-06-18 Fix some test programs to check whether an openssl binary is used which has the required functionality. Problem reported by Dirk Meyer.
2020-06-16 Fix file descriptor passing on FreeBSD. Problem reported by Dirk Meyer.
2020-06-14 Fix configure to actually check for inttypes.h so the macros like PRIX64 are available which then can be used to properly scan/print uint54_t values. Compiler warnings reported by Dirk Meyer.
2020-06-13 If SSL_CTX_dane_enable() is available then turn off hostname checks for DANE if only DANE-EE(3) type RRs are used.
2020-06-12 Fix compilation error of libmta/tlsdbg.c if TLS is not available. Bug reported by Dirk Meyer.
2020-06-07 Further workarounds for broken systems which return SERVFAIL for TLSA queries, e.g.,
```
_25._tcp.microsoft-com.mail.protection.outlook.com. TLSA
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 24819
```
Also ignore those failures if A/AAAA queries are insecure.
2020-05-28 pmilter support library: the maximum length of the value of a header that the parser accepts has been increased to 32K. This affects contrib/milter-regex.
2020-05-25 Allow to set multiple EC curves instead of just a single with the EC_curve option by providing a list.
2020-05-24 Fix implicit TLS handshake behaviour for smtps (described in RFC 8314).
2020-05-23 Fix a potential TLSv1.3 handshake problem (when a "Hello Retry Request" is used).
2020-04-16 Handle CNAMEs for "TLSA base domains".
2020-04-17 INCOMPATIBLE CHANGE: The protocol version for the internal communication between the MeTA1 processes has been changed, hence it is not possible to run programs from versions before and after the change together (which is not supported anyway).
2020-04-12 If a server has multiple IP addresses and there is a temporary failure during the SMTP dialogue when trying to deliver mail to it, do not try any of its other IPs (because the same host will most likely fail in the same way when contacted immediately again).
2020-01-05 Additional functions to handle MTA symbols are available for pmilters, the documentation has been updated accordingly.
