### Changes between 3.1.1 and 3.1.2 [xx XXX xxxx]
* Fix DH_check() excessive time with over sized modulus
The function DH_check() performs various checks on DH parameters. One of
those checks confirms that the modulus ("p" parameter) is not too large.
Trying to use a very large modulus is slow and OpenSSL will not normally use
a modulus which is over 10,000 bits in length.
However the DH_check() function checks numerous aspects of the key or
parameters that have been supplied. Some of those checks use the supplied
modulus value even if it has already been found to be too large.
A new limit has been added to DH_check of 32,768 bits. Supplying a
key/parameters with a modulus over this size will simply cause DH_check() to
fail.
