Clang requires the libatomic to be linked via LDFLAGS or else the linker
will fail to recognise __atomic macros.
An error as a result of not passing -latomic to the linker can be seen
below:
ld.lld: error: undefined symbol: __atomic_fetch_add_2
>>> referenced by sds.c:185
>>> lto.tmp:(sdsdupshared)
clang-10: error: linker command failed with exit code 1 (use -v to see invocation)

1. add eviction-lazyfree monitor
2. put eviction-del & eviction-lazyfree into eviction-cycle
that means eviction-cycle contains all the latency in
the eviction cycle including del and lazyfree
3. use getMaxmemoryState to check if we can break in lazyfree-evict

If client gets blocked again in `processUnblockedClients`, redis will not send
`REPLCONF GETACK *` to slaves untill next eventloop, so the client will be
blocked for 100ms by default(10hz) if no other file event fired.
move server.get_ack_from_slaves sinppet after `processUnblockedClients`, so
that both the first WAIT command that puts client in blocked context and the
following WAIT command processed in processUnblockedClients would trigger
redis-sever to send `REPLCONF GETACK *`, so that the eventloop would get
`REPLCONG ACK <reploffset>` from slaves and unblocked ASAP.

Allows for setting the binaries path if used outside the upstream repo.
Also documents `call` in usage clause (TODO: port to
`redis-cli --cluster call` or just deprecate it).
