Closes #240

This allows to operate submodule with the one-liner:

```
git submodule update --remote tarantool-sys/
```

This patch also updates the submodule in a mentioned way.

This commit reverts "build: fix libcrypto renaming" (9485e9c1). The fix
proposed in that commit actually broke the whole build instead of fixing
re-build. Since there are two `libcrypto.a` (tarantool one and symlinked
openssl), the linker sometimes loads the same library twice (`-lcrypto` and
`-lcrypto-ssl`).

This patch provides another solution - tarantool lib is renamed so now
`-lcrypto` uniquely corresponds to openssl and
`-ltcrypto` to the tarantool library.

While a replica is waiting for master's vclock to advance another
replica may become master. But the waiting replica will not know about
it, because this information is distributed via raft log, which is being
blocked by wait vclock.

also fixes docs in `node.rs`

and minor rpc fixes

Renaming libcrypto breaks the rebuid. Repro:

```bash
cargo build -vv
rm -rf target/debug/picodata-*
cargo build -vv
```

It results in

```
[build.rs:204] running ["cmake" "--build" "target/debug/build/tarantool-sys/tarantool-prefix/src/tarantool-build"]
gmake[2]: *** No rule to make target 'target/debug/build/tarantool-sys/openssl-prefix/lib/libcrypto.a', needed by 'src/tarantool'.  Stop.
```

Instead of renaming this patch makes a symlink.

Still ignore expelled ones though.
Also this introduces yet another hardcoded timeout value, which should
be unhardcoded at some point (related to #64).
