TLS is subject to downgrade attacks when SSLv3 is available, and
SSLv3 has vulnerabilities.
The popular solution is to disable SSLv3. On the web this breaks
some tiny number of very old clients. While Bitcoin RPC shouldn't
be exposed to the open Internet, it also shouldn't be exposed to
really old SSL implementations, so it shouldn't be a major issue
for us to disable SSLv3.
There is more information on the downgrade attacks and disabling
SSLv3 at https://disablessl3.com/ .

Just a pet peeve.
(PrintException has exactly the same body as PrintExceptionContinue but
does a re-throw at the end. Move these re-throws to the call
site, this aids understanding what is going on as well as eliminates a
bit of code duplication in util.cpp)
Remove unnecessary dependencies for bitcoin-cli
(leveldb, berkelydb, wallet, RPC server)
Build system changes:
- split libbitcoin.a into libbitcoin_common.a, libbitcoin_server.a and
libbitcoin_cli.a
Code changes (movement only):
- split up HelpMessage into HelpMessage in init.cpp and HelpMessageCli
in rpcclient.cpp
- move uiInterface from init.cpp to util.cpp
Split bitcoinrpc up into
- rpcserver: bitcoind RPC server
- rpcclient: bitcoin-cli RPC client
- rpcprotocol: shared common HTTP/JSON-RPC protocol code
One step towards making bitcoin-cli independent from the rest
of the code, and thus a smaller executable that doesn't have to
be linked against leveldb.
This commit only does code movement, there are no functional changes.
