This cleans up and simplifies the API by passing the command name as the
first argument. Previously the command name was specified explicitly,
but was still included in the argv.

* Introduce a new API's: RM_GetContextFlagsAll, and
RM_GetKeyspaceNotificationFlagsAll that will return the
full flags mask of each feature. The module writer can
check base on this value if the Flags he needs are
supported or not.
* For each flag, introduce a new value on redismodule.h,
this value represents the LAST value and should be there
as a reminder to update it when a new value is added,
also it will be used in the code to calculate the full
flags mask (assuming flags are incrementally increasing).
In addition, stated that the module writer should not use
the LAST flag directly and he should use the GetFlagAll API's.
* Introduce a new API: RM_IsSubEventSupported, that returns for a given
event and subevent, whether or not the subevent supported.
* Introduce a new macro RMAPI_FUNC_SUPPORTED(func) that returns whether
or not a function API is supported by comparing it to NULL.
* Introduce a new API: int RM_GetServerVersion();, that will return the
current Redis version in the format 0x00MMmmpp; e.g. 0x00060008;
* Changed unstable version from 999.999.999 to 255.255.255

The main motivation here is to provide a way for modules to create a
single, global context that can be used for logging.
Currently, it is possible to obtain a thread-safe context that is not
attached to any blocked client by using `RM_GetThreadSafeContext`.
However, the attached context is not linked to the module identity so
log messages produced are not tagged with the module name.
Ideally we'd fix this in `RM_GetThreadSafeContext` itself but as it
doesn't accept the current context as an argument there's no way to do
that in a backwards compatible manner.

This is essentially the same as calling COMMAND GETKEYS but provides a
more efficient interface that can be used in every context (i.e. not a
Redis command).

Avoid using a static buffer for short key index responses, and make it
caller's responsibility to stack-allocate a result type. Responses that
don't fit are still allocated on the heap.

This allows supplying secret configuration (for example - masterauth) via a secure channel
instead of having it in a plaintext file / command line param, while still allowing for most
of the configuration to reside there.
Also, remove 'special' case handling for --check-rdb which hasn't been relevant
since 4.0.0.

Adding [B]LMOVE <src> <dst> RIGHT|LEFT RIGHT|LEFT. deprecating [B]RPOPLPUSH.
Note that when receiving a BRPOPLPUSH we'll still propagate an RPOPLPUSH,
but on BLMOVE RIGHT LEFT we'll propagate an LMOVE
improvement to existing tests
- Replace "after 1000" with "wait_for_condition" when wait for
clients to block/unblock.
- Add a pre-existing element to target list on basic tests so
that we can check if the new element was added to the correct
side of the list.
- check command stats on the replica to make sure the right
command was replicated

I suppose that it was overlooked, since till recently none of the blocked commands were readonly.
other changes:
- add test for the above.
- add better support for additional (and deferring) clients for
cluster tests
- improve a test which left the client in MULTI state.

track and report memory used by clients argv.
this is very usaful in case clients started sending a command and didn't
complete it. in which case the first args of the command are already
trimmed from the query buffer.
in an effort to avoid cache misses and overheads while keeping track of
these, i avoid calling sdsZmallocSize and instead use the sdslen /
bulk-len which can at least give some insight into the problem.
This memory is now added to the total clients memory usage, as well as
the client list.

Adding -D option for redis-cli to control newline between command
responses in raw mode.
Also removing cleanup code before calling exit, just in order
to avoid adding more adding more cleanup code (redis doesn't
bother to release allocations before exit anyway)

I think the compiler would have removed this no-op anyways but it
definitely wasted me some 30 minutes on this :(
I was hoping I could remove the branch through some bit-hacking but
apparently its dead code :). Oh well, its 30 minutes of refreshing
bit hacking.

Add optional GET parameter to SET command in order to set a new value to
a key and retrieve the old key value. With this change we can deprecate
`GETSET` command and use only the SET command with the GET parameter.

This commit has two aspects:
1) improve memory reporting for all the places that use sdsAllocSize to compute
memory used by a string, in this case it'll include the internal fragmentation.
2) reduce the need for realloc calls by making the sds implicitly take over
the internal fragmentation of the block it allocated.
