RDMF (Redis/Disque merge friendlyness) refactoring WIP 1.

Fix redis-benchmark sds binding.

Same as redis-cli, now redis-benchmark requires to use hiredis sds copy
since it is different compared to the memory optimized fork of Redis
sds.

sds size classes - memory optimization

Geo: big refactoring of geo.c, zset.[ch] removed.

This commit simplifies the implementation in a few ways:

1. zsetScore implementation improved a bit and moved into t_zset.c where
is now also used to implement the ZSCORE command.

2. Range extraction from the sorted set remains a separated
implementation from the one in t_zset.c, but was hyper-specialized in
order to avoid accumulating results into a list and remove the ones
outside the radius.

3. A new type is introduced: geoArray, which can accumulate geoPoint
structures in a vector with power of two expansion policy. This is
useful since we have to call qsort() against it before returning the
result to the user.

4. As a result of 1, 2, 3, the two files zset.c and zset.h are now
removed, including the function to merge two lists (now handled with
functions that can add elements to existing geoArray arrays) and
the machinery used in order to pass zset results.

5. geoPoint structure simplified because of the general code structure
simplification, so we no longer need to take references to objects.

6. Not counting the JSON removal the refactoring removes 200 lines of
code for the same functionalities, with a simpler to read
implementation.

7. GEORADIUS is now 2.5 times faster testing with 10k elements and a
radius resulting in 124 elements returned. However this is mostly a
side effect of the refactoring and simplification. More speed gains
can be achieved by trying to optimize the code.

Geo: compile again with optimizations

For some reason the Geo PR included disabling the fact that Redis is
compiled with optimizations. Apparently it was just @mattsta attempt to
speedup the modify-compile-test iteration and there are no other
reasons.

Geo: JSON features removed

The command can only return data in the normal Redis protocol. It is up
to the caller to translate to JSON if needed.

[In-Progress] Add Geo Commands

Current todo:
- replace functions in zset.{c,h} with a new unified Redis
zset access API.

Once we get the zset interface fixed, we can squash
relevant commits in this branch and have one nice commit
to merge into unstable.

This commit adds:
- Geo commands
- Tests; runnable with: ./runtest --single unit/geo
- Geo helpers in deps/geohash-int/
- src/geo.{c,h} and src/geojson.{c,h} implementing geo commands
- Updated build configurations to get everything working
- TEMPORARY: src/zset.{c,h} implementing zset score and zset
range reading without writing to client output buffers.
- Modified linkage of one t_zset.c function for use in zset.c

Conflicts:
src/Makefile

Convert check-dump to Redis check-rdb mode

redis-check-dump is now named redis-check-rdb and it runs
as a mode of redis-server instead of an independent binary.

You can now use 'redis-server redis.

Convert check-dump to Redis check-rdb mode

redis-check-dump is now named redis-check-rdb and it runs
as a mode of redis-server instead of an independent binary.

You can now use 'redis-server redis.conf --check-rdb' to check
the RDB defined in redis.conf. Using argument --check-rdb
checks the RDB and exits. We could potentially also allow
the server to continue starting if the RDB check succeeds.

This change also enables us to use RDB checking programatically
from inside Redis for certain failure conditions.

Add "-lrt" in Makefile for Solaris.

This fix is from @NanXiao, however I was not able to retain authorship
because the Pull Request original repository was removed.

Set optional 'static' for Quicklist+Redis

This also defines REDIS_STATIC='' for building everything
inside src/ and everything inside deps/lua/.

Add quicklist implementation

This replaces individual ziplist vs. linkedlist representations
for Redis list operations.

Big thanks for all the reviews and feedback from everybody in
https://github.

src/Makefile: Reword "to run make test" message

Closes #1610

Add support for compiling on AIX

Closes #1900

ASCII sparklines generation API.

Latency monitor: basic samples collection.

HLLSELFTEST command implemented.

To test the bitfield array of counters set/get macros from the Redis Tcl
suite is hard, so a specialized command that is able to test the
internals was developed.

Sentinel test: Makefile target added.

Makefile: remove odd syntax not compatible with some make versions.

See issue #1448.

BLPOP blocking code refactored to be generic & reusable.
