Re: OpenSSL 1.1 breaks configure and more

Hi,

Here is an initial set of patches related to OpenSSL 1.1. Everything 
should still build fine on older OpenSSL versions (and did when I tested 
with 1.0.2h).

0001-Fixes-for-compiling-with-OpenSSL-1.1.patch

This patch fixes the code so it builds with OpenSSL 1.1 (except the 
CRYPTO_LOCK issue I have reported to the OpenSSL team).

- Makes our configure script check for SSL_new instead
- Uses functions instead of direct access to struct members

0002-Define-CRYPTO_LOCK-for-OpenSSL-1.1-compat.patch

Fix for the removal of the CRYPTO_LOCK define. I am trying to convince 
them to add the define back. :)

0003-Remove-OpenSSL-1.1-deprecation-warnings.patch

Silence all warnings. This commit changes more things and is not 
necessary for getting PostgreSQL to build against 1.1.

- Silences deprecation other warnings related to that OpenSSL 1.1 now 
1) automatically initializes the library and 2) no longer uses the 
locking callback.
- Silences deprecation warning when generating DH parameters.
