Merge src/leveldb changes for LevelDB 1.18.
openssl version bump

Bumps the OpenSSL version to the latest release, and kills SSL2. (SSL3 was already killed here, so I'm not sure why SSL2 was left around?)

No other changes.
Add doc/doxygen to .gitignore
Extend getchaintips RPC test.

Add the capability to simulate network splits to the RPC test framework
and use it to do more extensive testing of 'getchaintips'.
Work around #5113.
Clear vFixedSeeds for regtest network

It shouldn't inherit these from testnet.
(seems to be already done for unit test network but forgotten here...)
Fixes #5127.
