Saner VM defaults for redis.conf

VM now is able to block clients on swapped keys for all the commands

ZCOUNT and ZRANGEBYSCORE new tests

ZRANGEBYSCORE now supports open intervals, prefixing double values with a open paren. Added ZCOUNT that can count the elements inside an interval of scores, this supports open intervals too

WITHSCORES in ZRANGEBYSCORE thanks to Sam Hendley

DEBUG OBJECT provide info about serialized object length even when VM is disabled

multi bulk requests in redis-benchmark, default fsync policy changed to everysec, added a prefix character for DEBUG logs

APPEND tests

APPEND command

Faster version of the function hashing possibly encoded objects, leading to a general speed gain when working with Sets of integers

faster Set loading time from .rdb file resizing the hash table to the right size before loading elements

Fixed VM corruption due to child fclosing the VM file directly or indirectly calling exit(), now replaced with _exit() in all the sensible places. Masked a few signals from IO threads.

loading side of the threaded VM

TODO cahnges

Fixed memory human style memory reporting, removed server.usedmemory, now zmalloc_used_memory() is used always.

VM tuning thanks to redis-stat vmstat. Now it performs much better under high load

Changelog updated

REDIS_MAX_COMPLETED_JOBS_PROCESSED is now in percentage, not number of jobs. Moved a debugging message a few lines forward as it was called where a few logged parameters where invalid, leading to a crash

fixed a deadlock caused by too much finished processes in queue so that I/O clients writing to the wirte side of the pipe used to awake the main thread where blocking. Then a BGSAVE started waiting for the last active thread to finish, condition impossible because all the I/O threads where blocking on threads. Takes this as a note to myself...

ae.c event loop does no longer support exception notifications, as they are fully pointless. Also a theoretical bug that never happens in practice fixed.

commercial tools stuff removed from the Redis makefile. cotools are now migrated into a different repos

removed a bug in the function to cancel an I/O job

static symbols update

removed support for REDIS_HELGRIND_FRIENDLY since Helgrind 3.5.0 is friendly enough even with many threads created and destroyed

now redis-cli understands -h

Create swap file only if not exists

I hate warnings

fixed a minor memory leak in configuration file parsing

minor fix

support for named VM swap file. Fixed a few important interaction issues between the background saving processes and IO threads
