779aebc91c Module API for loading and saving long double 
looks like each platform implements long double differently (different bit count)
so we can't save them as binary, and we also want to avoid creating a new RDB
format version, so we save these are hex strings using "%La".

This commit includes a change in the arguments of ld2string to support this.
as well as tests for coverage and short reads.

- Add RM_GetServerInfo and friends
- Add auto memory for new opaque struct
- Add tests for new APIs

other minor fixes:
- add const in various char pointers
- requested_section in modulesCollectInfo was actually not sds but char*
- extract new string2d out of getDoubleFromObject for code reuse

91f4bdc9f9 Modules: block on keys: use a better interface. 
Using the is_key_ready() callback plus the reply callback later, creates
different issues AFAIK:

1. More complex API.
2. We need to call the reply callback() ASAP if the is_key_ready()
interface returned success, however the internals do not work in that
way, so when the reply callback is called the setup could be different.
To fix that, there is to break the current design that handles the
unblocked clients asyncrhonously, and run the list ASAP.

51c3ff8d75 Modules hooks: complete missing hooks for the initial set of hooks 
* replication hooks: role change, master link status, replica online/offline
* persistence hooks: saving, loading, loading progress
* misc hooks: cron loop, shutdown, module loaded/unloaded
* change the way hooks test work, and add tests for all of the above

startLoading() now gets flag indicating what is loaded.
stopLoading() now gets an indication of success or failure.
adding startSaving() and stopSaving() with similar args and role.

e978bdf9ef Module API for controlling LRU and LFU, and OpenKey without TOUCH 
Some commands would want to open a key without touching it's LRU/LFU
similarly to the OBJECT or DEBUG command do.

Other commands may want to implement logic similar to what RESTORE
does (and in the future MIGRATE) and get/set the LRU or LFU.

* create module API for forking child processes.
* refactor duplicate code around creating and tracking forks by AOF and RDB.
* child processes listen to SIGUSR1 and dies exitFromChild in order to
  eliminate a valgrind warning of unhandled signal.
* note that BGSAVE error reply has changed.

valgrind error is:
  Process terminating with default action of signal 10 (SIGUSR1)

eaafea4828 Modules API: experimental APIs version. 
This way it is possible to use conditional compilation to be compatible
with a larger amount of Redis versions, however note that this breaks
binary compatibiltiy, so the module must be compiled with the
corresponding redismodule.h file depending on the version of Redis
targeted.

Note that this was an experimental API that can only be enabled with

promoted to stable API. Sorry for the breakage, it is trivial to
resolve btw. This change will not be back ported to Redis 4.0.
