The test-rand RNG was returning success when it had some but insufficient data.
Now, it returns failure and doesn't advance the data pointer.
The test-rand RNG was failing when a parent was specified. This case is now
ignored.

The exclusion of SHA1 for X509 signatures is not obvious as the "intuative"
idea is that SHA1 should have 80 security bits. However the security bits
of SHA1 are explicitly set to 63 to avoid the it being strong enough for
security level 1. x509_set.c has the comment:
/*
* SHA1 and MD5 are known to be broken. Reduce security bits so that
* they're no longer accepted at security level 1.
* The real values don't really matter as long as they're lower than 80,
* which is our security level 1.

If an application bug means that a buffer smaller than is necessary is
passed to various functions then OpenSSL does not spot that the buffer
is too small and fills it anyway. This PR prevents that.
Since it requires an application bug to hit this problem, no CVE is
allocated.
