Fix 1f41da64 was reverted because it broke unix sockets with relative
path and exception messages in redis.c and library.c

* Fix `connect` for port numbers >=32768:

Since 5.0.0, using a high enough port number gives a "No such file or directory" error, because type casts treat high ports as -ve which awkwardly triggers the unix-socket-path behaviour.

* clean up guard condition

Adds an option to process the actual strings in simple string replies as
opposed to translating them to `true`.  This only applies to
`rawCommand` and `eval` because as far as I know know vanilla Redis
command attaches any information besides `OK` to simple string replies.

This PR fixes issue #1504.

This PR fixes issue #1504.

RedisCluster currently has a high construction overhead because
every request has to issue a CLUSTER SLOTS command to map the
keyspace.  The issue is especially evident when a request only
does a few commands.

This commit removes support for PHP 5 by getting rid of all of our Zend
compatibility layer methods, as well as any call checking against
PHP_MAJOR_VERSION or ZEND_MODULE_API_NO.

Unit tests are all passing for Redis, RedisCluster, and RedisArray but
this should still be considered a work in progress until more testing
can be done.

Addresses issue #1448

This should fix the XCLAIM issue on 32-bit PHP installs.

This change will allow the user to pass the XCLAIM TIME option pretty much any way they want (string, long, or float) and it should work.  Note that in 32-bit PHP they will only be able to pass exact values <= 2^53 as PHP will use a double precision floating point for integer overflows.

* Reset the socket after a timeout to make sure no wrong data is received

* Remove the lazy_connect completely

* Missing TSRMLS_CC

* Remove redundant check if the stream exists

* Add the redis_sock_server_open to the CLUSTER_SEND_PAYLOAD macro
