* Remove the mbedtls namespacing from the header file, to fix a "file not found"
build error. Fixed by Haijun Gu #2319.
* Fix returning the value 1 when mbedtls_ecdsa_genkey failed.
+ * Server's RSA certificate in certs.c was SHA-1 signed. In the default
+ mbedTLS configuration only SHA-2 signed certificates are accepted.
+ This certificate is used in the demo server programs, which lead the
+ client programs to fail at the peer's certificate verification
+ due to an unacceptable hash signature. The certificate has been
+ updated to one that is SHA-256 signed. Fix contributed by
+ Illya Gerasymchuk.
