Simplifies code and reduces risk of overflow from converting length
field in X replies from words to bytes.
One call to _XEatData is left in ephyrHostGLXGetStringFromServer where
it's already been checked for overflow, and other values have been
subtracted from it to reduce the size of data remaining to be eaten.

reply.length & reply.size are CARD32s and need to be bounds checked before
multiplying or adding to come up with the total size to allocate, to avoid
integer overflow leading to underallocation and writing data from the
network past the end of the allocated buffer.

The formatter confused address operators preceded by casts with
bitwise-and expressions, placing spaces on either side of both.
That syntax isn't used by ordinary address operators, however,
so fix them for consistency.

Similar to how we intercept and pass through CreateContext, also pass
through newer CreateNewContext requests.

We need to pass these requests through to the host server in the same
way we do glXMakeCurrent. Generalise the existing MakeCurrent
submission into once that will send MakeCurrent, MakeContextCurrent or
MakeCurrentReadSGI, depending on the request and the host server's
capabilities, and add decoding/hijack support for incoming
MakeContextCurrent and MakeCurrentReadSGI requests.

This is strictly the application of the script 'x-indent-all.sh'
from util/modular. Compared to the patch that Daniel posted in
January, I've added a few indent flags:
-bap
-psl
-T PrivatePtr
-T pmWait
-T _XFUNCPROTOBEGIN
-T _XFUNCPROTOEND
-T _X_EXPORT
The typedefs were needed to make the output of sdksyms.sh match the
previous output, otherwise, the code is formatted badly enough that
sdksyms.sh generates incorrect output.
The generated code was compared with the previous version and found to
be essentially identical -- "assert" line numbers and BUILD_TIME were
the only differences found.
The comparison was done with this script:
dir1=$1
dir2=$2
for dir in $dir1 $dir2; do
(cd $dir && find . -name '*.o' | while read file; do
dir=`dirname $file`
base=`basename $file .o`
dump=$dir/$base.dump
objdump -d $file > $dump
done)
done
find $dir1 -name '*.dump' | while read dump; do
otherdump=`echo $dump | sed "s;$dir1;$dir2;"`
diff -u $dump $otherdump
done

We can now launch GL or XV apps in any of the
Xephyr screens we want.
* hw/kdrive/ephyr/hostx.c,h:
(hostx_get_window):
(hostx_create_window): make these functions be screen
number aware.
* hw/kdrive/ephyr/XF86dri.c : fix some compiler warnings.
* hw/kdrive/ephyr/ephyrdri.c:
(ephyrDRIQueryDirectRenderingCapable),
(ephyrDRIOpenConnection),
(ephyrDRIAuthConnection),
(ephyrDRICloseConnection),
(ephyrDRIGetClientDriverName),
(ephyrDRICreateContext),
(ephyrDRIDestroyContext),
(ephyrDRICreateDrawable),
(ephyrDRIGetDrawableInfo),
(ephyrDRIGetDeviceInfo): in all those functions, don't forward
the screen number we receive - from the client - to the host X.
We (Xephyr) are always targetting the same X display screen, which is
the one Xephyr got launched against. So we enforce that in the code.
* hw/kdrive/ephyr/ephyrdriext.c:
(EphyrMirrorHostVisuals): make this duplicate the visuals of the host X
default screen into a given Xephyr screen. This way we have a chance
to update the visuals of all Xephyr screen to make them mirror those
of the host X.
(many other places): specify screen number where required by the api
change in hostx.h.
* hw/kdrive/ephyr/ephyrglxext.c: specify screen number where required
by the api change in hostx.h
* hw/kdrive/ephyr/ephyrhostglx.c: don't forward the screen number we
receive - from the client - to the host X.
We (Xephyr) are always targetting the same
X display screen, which is
the one Xephyr got launched against. So we enforce that in the code.
* hw/kdrive/ephyr/ephyrhostvideo.c,h: take in account the screen number received
from the client app. This is useful to know on which Xephyr screen we
need to display video stuff.
* hw/kdrive/ephyr/ephyrvideo.c: update this to reflect the API change
in hw/kdrive/ephyr/ephyrhostvideo.h.
(ephyrSetPortAttribute): when parameters are not valid
- they exceed their validity range - send them to the host anyway
and do not return an error to clients.
Some host expose buggy validity range, so rejecting client for that
is too harsh.
* hw/kdrive/ephyr/ephyrdri.c:
(ephyrDRIGetDrawableInfo): quickly hook
this into getting the drawable info from the host
X server. For the time being, this only gets the drawable info
of the Xephyr main window in the host. It should really get
the info of a the peer drawable in the host X. So there should be a
peer drawable to begin with.
* hw/kdrive/ephyr/ephyrdriext.c:
(ProcXF86DRIGetDrawableInfo): some cleanups. Properly get the
the drawable info otherwise there is a host X hang.
* hw/kdrive/ephyr/ephyrhostglx.c: do not
(ephyrHostGLXQueryVersion): do not use C bindings of the glx protocol
calls. Some of those actually access DRI context directly, resulting
in the context having three clients. Instead all XF86DRI proto
fowarding request should be coded by hand and only forward the
protocol requests
* hw/kdrive/ephyr/ephyrglxext.c:
fixed various logging functions
(ephyrGLXGetStringReal): make sure all the string is sent to clients
including the ending zero.
* hw/kdrive/ephyr/ephyrhostglx.c:
(ephyrHostGLXGetStringFromServer): better error handling.
(ephyrHostGLXSendClientInfo): ditto.
(ephyrHostGLXMakeCurrent): ditto
* hw/kdrive/ephyr/ephyr.c:
(EphyrDuplicateVisual): when duplicating the
visual, copy the color component masks and the class
from the hostX
(EphyrMirrorHostVisuals): don't mix blue and green mask.
* hw/kdrive/ephyr/ephyrdri.c: add more logs.
(ephyrDRICreateDrawable): actually implement this.
for the moment it creates a DRI drawable for the hostX window,
no matter what drawable this call was issued for.
(ephyrDRIGetDrawableInfo): actually implemented this.
for the moment the drawable info queried for its attrs is the
Xephyr main main window.
* hw/kdrive/ephyr/ephyrdriext.c:
(ProcXF86DRIGetDrawableInfo): properly hook this dispatch
function to the ephyrDRIGetDrawableInfo() function.
* hw/kdrive/ephyr/ephyrglxext.c: add a bunch of GLX implementation hooks
here. Hijack some of the xserver GLX hooks with them. Still need to
properly support byteswapped clients though.
* hw/kdrive/ephyr/ephyrhostglx.c,h: actually implemented the protocol
level forwarding functions used by the GLX entr points in
ephyrglxext.c. Here as well, there are a bunch of them, but we are
far from having implemented all the GLX calls.
* hw/kdrive/ephyr/hostx.c,h:
(hostx_get_window_attributes): added this new entry point
(hostx_allocate_resource_id_peer): added this to keep track of
resource IDs peers: one member of the peer is in Xephyr, the other
is in host X.
(hostx_get_resource_id_peer): ditto.
* hw/kdrive/ephyr/ephyrglxext.c:
(ephyrGLXGetFBConfigsSGIX): proxy the GLXGetFBConfigsSGIX call.
It is a vendor extension to get the visual configs as a list of
name/value pairs.
(ephyrHijackGLXExtension): hijack the VendorPriv_dispatch_info
dispatch table to register our implementation of GLXGetFBConfigsSGIX
(ephyrGLXGetFBConfigsSGIXReal): added this where the real
implementation of GLXGetFBConfigsSGIX is. It support bytes swapping.
(ephyrGLXGetFBConfigsSGIX,ephyrGLXGetFBConfigsSGIXSwap): these are
the dispatch entry points. They just call
ephyrGLXGetFBConfigsSGIXReal.
* hw/kdrive/ephyr/ephyrhostglx.c,h: reorganize the proxies to get
visual params from the host so that they clearly support the different
methods of doing so.
* hw/kdrive/ephyr/XF86dri.c: re format this correctly.
Make function decls honour the Ansi-C standard.
* hw/kdrive/ephyr/ephyr.c: protect glx/dri related
extension initialisation with the XEPHYR_DRI
macro. Initialize the GLX ext hijacking
at startup.
* hw/kdrive/ephyr/ephyrdri.c: add more logging to ease debugging
* hw/kdrive/ephyr/ephyrdriext.c: ditto. reformat.
* hw/kdrive/ephyr/ephyrglxext.c,h: add this extension to
proxy GLX requests to the host X. started to proxy those nedded to
make glxinfo work with fglrx. Not yet finished.
* hw/kdrive/ephyr/ephyrhostglx.c,h: put here the actual
Xlib code used to hit the host X server because Xlib stuff cannot be
mixed with xserver internal code, otherwise compilation erros due to
type clashes happen. So no Xlib type should be exported by the
entrypoints defined here.
