ad5393296f (1623) xkb: split XkbSendMap()
This function is a funny beast: it assembles and writes out an xkbGetMapReply,
called in two different cases, ProcXkbGetMap() as well as ProcXkbGetKbdByName().
In the latter case the whole reply is contained in another one. That's the reason
why it's payload size is computed separately - the caller must know that in order
to set up the container's reply size correctly.

As preparation for upcoming simplifications of the reply send path, splitting off
this function into pieces: XkbAssembleMap() just assembles the reply payload,
while it's callers now responsible for preparing the request header and writing
out both pieces.

ae58654783 (1623) xkb: ProcXkbGetKbdByName(): static initialization of sub-reply structs
For easier reading, move th sub-reply structs down to where they're used
first and use static initialization for the common fields.

a2db290097 (1623) xkb: ProcXkbGetKbdByName() simplify reply struct initialization
Move down the declaration of the reply struct, right before swapping and sending
and use static initialization.

6a92902cf8 (1623) xkb: XkbSendGeometry(): pass in struct as value instead of pointer
The function doesn't need to pass anything back via this pointer, it's
the last consumer of this struct. Make understanding the code a bit easier
and clear the road for further simplifications by passing the struct as
value instead of pointer.

527ccda60c (1623) xkb: CheckDeviceLedFBs(): untwist parameters
It's hard to see which fields of the xkbGetDeviceInfoReply struct it's
reading or writing, and that complicates further simplifications of the
caller. So instead let the caller pass in the relevant fields and do the
modifications on the reply structs on its own.

b36cdfd3d5 (1623) xkb: XkbSendIndicatorMap(): little simplification
A bit simplification in code flow.
The extra length check (did we write as much as intended?) isn't necessary,
since the buffer size is computed by the very same data before this
function is called.

Hint: the size computation must be done before calling this one, because
the reply might be encapsulated in another one (xkbGetKbdByName).
