glx: Track GLX 1.3 style GLX drawables under their X drawable ID as well
This ensures that the DrawableGone callback gets called as necessary
when the X drawable goes away. Otherwise, using a GLX drawable
(say, glXSwapBuffers) in indirect mode after the X drawable has been
destroyed will crash the server.

glx: Let the resource system destroy pixmaps
GLX pbuffers are implemented using a pixmap allocated by the server.
With the change to DRI2 to track DRI2 drawables as resources, we need to make
sure that every drawable we create a DRI2 drawable for has an XID. By
using the XID of the pbuffer, the resource system will automatically
reclaim the hidden pixmap and the DRI2 drawable when the pbuffer is
destroyed or the client exits.

DRI2: Track DRI2 drawables as resources, not privates
The main motivation here is to have the resource system clean up the
DRI2 drawable automatically so glx doesn't have to. Right now, the
glx drawable resource must be destroyed before the X drawable, so that
calling DRI2DestroyDrawable doesn't crash. By making the DRI2
drawable a resource, GLX doesn't have to worry about that and the
resource destruction order becomes irrelevant.

DRI2: fixup handling of last_swap_target
We need to initialize the swap target, which is passed to the driver to
schedule events. Rather than using -1 to indicate that the field is
uninitialized, just make sure we initialize it at drawable creation
time.

DRI2WaitSbc(): Fixes for correct semantic of glXWaitForSbcOML()
Added implementation for case target_sbc == 0. In that case, the
function shall schedule a wait until all pending swaps for the drawable
have completed.
Fix for non-blocking case. Old implementation returned random,
uninitialized values for (ust,msc,sbc) if it returned immediately
without scheduling a wait due to sbc >= target_sbc.
Now if function doesn't schedule a wait, but returns immediately,
it returns the (ust,msc,sbc) of the most recently completed swap,
i.e., the UST and MSC corresponding to the time when the returned
current SBC was reached.

DRI2: fix swapbuffers handling of SBC and target MSC
Returns expected SBC after completion of swap to caller, as required by
OML_sync_control spec, instead of the last_swap_target value.
Passes target_msc, divisor, remainder, correctly for
glXSwapBuffersMscOML() call, while retaining old behaviour for simple
glXSwapBuffers() call.
An OML swap can have a 0 target_msc, which just means it needs to
satisfy the divisor/remainder equation. Pass this down to the driver as
needed so we can support it.

DRI2: drawable lifetime fixes
Handle drawable destruction and lifetime correctly.
Check whether the drawable priv is valid in DRI2SwapInterval(),
DRI2WaitSBC() and DRI2WaitMSC(); it may have gone away, so be sure to
check it before using it.
If more than 1 outstanding swap is queued, we may complete several after
an app has exited. If we free it after the first one completes and the
refcount reaches 0, we'll crash the server on subsequent completions.
So delay freeing until all swaps complete and remove the error message
as this is a normal occurence. To do this properly, we must also avoid
destroying drawables in DRI2DestroyDrawable() if a swap or wait event is
pending.
And finally, make sure we free drawables in DRI2WaitMSCComplete() if
necessary (i.e. if the refcount has reached 0 and this MSC was the last
pending event on the object).

DRI2: advertise lowest supported DRI2 protocol version
Update our supported DRI2 protocol version as each driver does
DRI2ScreenInit, since depending on available kernel features, each DDX
may support different callbacks and therefore protocol.

DRI2: throttle swaps at submission time too
We need to throttle swaps here in addition to when the context is made
current to avoid causing problems with clients that just swap.
Throttling here also ensures our swaps get ordered as long as we block
the client occasionally.

DRI2: handle swapsPending better
Avoid a potential swapsPending underflow by incrementing it before
ScheduleSwap, which may complete it immediately. And be sure to

DRI2: prevent swap wakes from waking MSC waiters
If a few swaps were queued leading to a throttle related block on the
client, and then the client submitted an MSC wait, one of the previous
swap wakeups could have caused the MSC wait to complete early. Add a
flag for this to prevent a swap wake from prematurely waking an MSC
waiter.

dix: Update element count in FreeResource*()
FreeResource() keeps clientTable[cid].elements up to date with the
number of resources allocated to the client. The other free
resource functions (FreeResourceByType(),
FreeClientNeverRetainResources() and FreeClientResources()) don't
maintain this invariant.
Typically, the only consequence is that the element count is too high
and we end up allocating the hash table bigger than necessary. However,
FreeResource() also relies on the element count to restart the search if
the list of resources has been changed during a resource destruction
callback. Since FreeResourceByType() doesn't update the count, if we call
that from a resource destruction callback from FreeResource(), the
loop isn't restarted and we end up following an invalid next pointer.
Furthermore, LookupClientResourceComplex() and
FreeClientNeverRetainResources() don't use the element count to detect
if a callback deleted a resource and may end up following an invalid
next pointer if the resource system is called into recursively.

glxdri2: Hard-code the extension version we need
If we use the #define'd version from dri_interface.h, the server will
require at least that version of the extension. If we're compiling against
a dri_interface.h with a newer version we don't really require, glxdri2
will require a too high version of the extension.
The right approach is to just hard-code the version we need instead of
using the #defines.

dri2: Take an XID for tracking the DRI2 drawable
Some pixmaps (window pixmaps and scratch pixmaps) don't have the
drawable->id set and thus DRI2 gets confused when using that field
for looking up the DRI2 drawable. Go back to using privates for getting
at the DRI2 drawable from a DrawablePtr. We need to keep the resource
tracking in place so we can remove the DRI2 drawable when the X resource
it was created for goes away. Additionally, we also now track the DRI2
drawable using a client XID so we can reclaim the DRI2 drawable even if
the client goes before the drawable and doesn't destroy the DRI2 drawable.

DRI2: Don't return junk reply instead of blocking in glXWaitForSbcOML()
DRI2WaitSBC() didn't block if requested targetSBC wasn't yet reached.
Instead it returned a xreply with uninitialized junk return values, then
blocked the connection until targetSBC was reached.
Therefore the client didn't block, but continued with bogus return
values from glXWaitForSbcOML.
This patch fixes the problem by implementing DRI2WaitSBC similar
to the clean and proven DRI2WaitMSC implementation.

DRI2/xserver: Don't hang in glXSwapBuffers if drawable moves between crtc's (bug 28383)
Detect if a drawable has been moved from an original crtc to a new crtc
with a lower current vblank count than the original crtc inbetween
glXSwapBuffers() calls. Reinitialize drawable's last_swap_target
before scheduling next swap if such a move has taken place.
last_swap_target defines the baseline for scheduling the next swap.
If a movement between crtc's is not taken into account, the swap may
schedule for a vblank count on the new crtc far in the future, resulting
in a apparent "hang" of the drawable for a long time.
Fixes Bugzilla bug #28383.
