Fix engine/renderer timings synchronization. Bump to RefAPI 6 v3 APPLIED

This set of patches fixes the earliest bug since renderers split:
timings.

It eliminates the need to synchronize renderers timings by passing a
pointer from engine to renderer in a form of API structure. The
structure in the API was designed to be compatible with internal engine
structures that holds these values.

It also fixes another bug: truncated client time. For some reason it
was in single-precision float all this time and nobody noticed.

Possible Questions:

Q: Why have structures when it's possible to pass separate pointers to
   double?

A: I had this in the non-published version of RefAPI 6 however turning
   gpGlobals->time into a pointer enables dereferencing it.
   The -> operator does two things here: it will be always evaluated
   FIRST (as of C standard) and it already dereferences the pointer.
   I thought it's more aethetically pleasant to work with a structure
   than a single variable pointer.
   The downside of this is a set of static assertions in the engine,
   however it's an engine problem to keep it compatible.

Q: Why not to rename everything in the engine to use these shared
   structures?

A: I considered this too but didn't want to go with this, as replacing
   every cl.{time,oldtime} and host.{realtime,frametime} into something
   else would probably not only touch hundreds of lines in renderers
   but thousands in the engine. Also calling client time cl.time just
   makes sense.

Changes since v1:
* As suggested by mittorn, we now use PARMs to get engine pointers.
* It also eliminates older functions that were introduced in RefAPI 5.
* ref_client_t and ref_host_t now expose more data to avoid excessive
  EngineGetParm calls. Though not everything was replaced, it's outside
  of the scope of this patch set and can be easily fixed later without
  breaking compatibility. 

Changes since v2:
* No changes. Sorry, I put wrong in-reply-to.
