mentions 3 security issues, at least CVE-2017-2784 (Freeing of memory
allocated on stack when validating a public key with a secp224k1 curve)
affects mbedtls-2.2.1.
Packaging:
- bump major of shared libs since symbols have been removed
- tweak license marker
- kill code in testsuite that fails to build with our stdio
implementation (can't take the address of stdout, the C standard
warns about that)
- kill some debug flags set by cmake
Make test passes on amd64 and arm, also tests & ok juanfra@

* Lowest common hash was selected from signature_algorithms extension in
TLS 1.2 (found by Darren Bane) (introduced in 1.3.8).
* Remotely-triggerable memory leak when parsing some X.509 certificates
(server is not affected if it doesn't ask for a client certificate)
(found using Codenomicon Defensics).
* Remotely-triggerable memory leak when parsing crafted ClientHello
(not affected if ECC support was compiled out) (found using Codenomicon
Defensics).
- includes a fix for CVE-2014-4911 (DoS)
- delete patches committed upstream
- unbreak sparc64
- new features, see ChangeLog
Regress tests pass on amd64 and sparc64.
