The request struct's length fields aren't used anymore - we have the
client->req_len field instead, which also is bigreq-compatible.

The authorative source of the request frame size is client->req_len,
especially with big requests larger than 2^18 bytes.

Most of the complexity here isn't needed at all. It can be really trivial,
since we just have one operation anyways.
It's also much cleaner to use the defines from proto headers instead of
raw numbers.

In order to allow simplifying the reply send path, collect the reply
fragments into one buffer, instead of arbitrary number of WriteToClient()
calls. This also makes it much easier for potentially new purely packet-based
transports which (eg. binder) that would need their own stream parsing logic.
This xres function is an exceptionally hard case, since payload is constructed
step by step, and it's size only known when finished. The current way of the
fragment handling still has lots of room for improvement (eg. using very small
number of allocations), but leaving this for later exercise.

Collect the few bits in a local array, so one WriteToClient() call is
sufficient. That's also easing further simplifications in upcoming commits.

Simplify allocaton by putting the small temporary int array onto stack.
This also allows further simplifications by upcoming commits.
The upper bound is determined by the number of resource types registered
in the server - this can only be increased by writing new extensions.

Note: there's an upper bound by compile time defines (theoretically, can
be increased by special cmdline args, that virtually nobody ever using).

Simplify the dispatching by moving the branching between Xinerama
vs. single screen into the actual request handlers.

Split reply header and payload buffers. Making it more coherent with all the
other request handlers, and allows a lot of further simplification by using
generic macros (coming in subsequent commits).

There's some piece ifdef'ed code that doesn't serve any practical purpose.
Instead add a little comment telling why that funny way of dispatching
(based on request size) is necessary.

We alread have several of these calls, that aren't interested in result value,
explicitly casting to void. Fixing this up for the remaining ones.
This is helpful for the human reader as well as quality analysis tools.
