Unlike original reference code, Redis uses 64bit variable, so half the bits make it 32bit, not 16

Slight robustness improvement, especially if the limit values are changed, as was suggested in antires/redis#4291 [1]. [1] https://github.com/antirez/redis/pull/4291

By grepping the continuous integration errors log a number of GEORADIUS tests failures were detected. Fortunately when a GEORADIUS failure happens, the test suite logs enough information in order to reproduce the problem: the PRNG seed, coordinates and radius of the query. By reproducing the issues, three different bugs were discovered and fixed in this commit. This commit also improves the already good reporting of the fuzzer and adds the failure vectors as regression tests. The issues found: 1. We need larger squares around the poles in order to cover the area requested by the user. There were already checks in order to use a smaller step (larger squares) but the limit set (+/- 67 degrees) is not enough in certain edge cases, so 66 is used now. 2. Even near the equator, when the search area center is very near the edge of the square, the north, south, west or ovest square may not be able to fully cover the specified radius. Now a test is performed at the edge of the initial guessed search area, and larger squares are used in case the test fails. 3. Because of rounding errors between Redis and Tcl, sometimes the test signaled false positives. This is now addressed. Whenever possible the original code was improved a bit in other ways. A debugging example stanza was added in order to make the next debugging session simpler when the next bug is found.

They were under /deps since they originate from a different source tree, however at this point they are very modified and we took ownership of both the files making changes, fixing bugs, so there is no upgrade path from the original code tree. Given that, better to move the code under /src with proper dependencies and with a more simpler editing experience.

Instead of successive divisions in iteration the new code uses bitwise magic to interleave / deinterleave two 32bit values into a 64bit one. All tests still passing and is measurably faster, so worth it.

The GIS standard and all the major DBs implementing GIS related functions take coordinates as x,y that is longitude,latitude. It was a bad start for Redis to do things differently, so even if this means that existing users of the Geo module will be required to change their code, Redis now conforms to the standard. Usually Redis is very backward compatible, but this is not an exception to this rule, since this is the first Geo implementation entering the official Redis source code. It is not wise to try to be backward compatible with code forks... :-) Close #2637.

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.

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 src/redis.c
