[openssl-dev] sizeof (HMAC_CTX) changes with update, breaks binary compatibility

[Peter Waltenberg]

Which is exactly why our hacked version of OpenSSL has
allocators/deallocators for all these private struct's.

It'd be really nice if OpenSSL would fix this, adding them won't break
backwards compatibility (i.e. API breakage isn't an excuse for not fixing
these)  and going forwards problems like this would stop occuring.
