Prototypes are fixed, and we don't need to flush on wakeup.

This will hide all sorts of extension stuff from us.

I'm experimenting with that because of conflicts with GL dispatch tables.

If the address of the swapped memory location is known at compile time,
we can check its alignment at no runtime cost and use lswapl instead.

Should be safe since cpswap isn't used on pointers.

The original macros are retained (instead of replacing them with inline
functions) because of implicit type promotion. That is, an int16 passed
to an inline function taking int32 would be implicitly promoted to int32
without a warning.

Swapping the wrong size was never caught because swap{l,s} are macros.

It's clear in the case of Xext/xres.c, that the author believed
client_major/minor to be CARD16 from looking at the code in the first
hunk.

v2: dmx.c fixes from Keith.

The developer docs are generated from a subset of docbook.am
which is sometimes updated.

The one difference for xserver is the embedded css style in the HEAD element.

Rather than referring to the external xorg.css stylesheet, embed the content
of the file in the html output produced. This is accomplished by using
version 1.10 of xorg-xhtml.xsl.

This makes the whole html docs tree much more relocatable.
In addition, it eliminates xorg.css as a runtime file which makes
xorg-sgml-doctools a build time only package.

Adding support in libX11 for html chunking caused a reorg of docbook.am
as well as the xorg-sgml-doctools masterdb for olinking.
The parameter img.src.path is added for pdf images.
A searchpath to the root builddir is added for local entities, if present.
This feature was initiated by xserver module and made available to all.

The docbook.am makefile hides all the details and is identical for
all 22 modules having DocBook documentation. It is included by a thin
Makefile.am which requires no docbook knowledge.
