This is a slight generalization of the existing SGI and MESA swap
control extensions, and a prerequisite for GLX_EXT_swap_control_tear.

It wouldn't work in any case, as the internal API only stores a signed
int, and GLX_EXT_swap_control_tear will overload the meaning of negative
values so we should avoid ambiguity.
If your application needs a swap interval in excess of ~414.25 days, I'm
very sorry.

I find the __glX naming convention distasteful for a bunch of reasons,
not least that I expect "vi -t glXBindTexImageEXT" to take me someplace
useful. The functions we're referencing here should not be exported from
libGL (hence the static / _X_HIDDEN) but that's no reason not to name
them correctly.
This does have one possible, very minor, correct functional change,
glXGetMscRateOML now returns Bool (unsigned int) instead of GLboolean
(unsigned char); if your psABI really only writes to a single byte of
the return register when the return type is char-like, then we probably
would not have returned false when we meant to. At least for amd64 this
does not seem to be an issue; the old code wrote 0 to %eax, the new code
does a zero-extended load from %al to %eax (since the internal function
still returns GLboolean).

There is one more thing which disallow us to easily fix it are different element sizes
for instance: `glx_config_create_list` allocates memory just for `glx_config`,
`driwindowsMapConfigs` for `driwindows_config` and
`createDriMode` for `__GLXDRIconfigPrivate`.
Yes it is possible but size of such fix
will be more big and complex than original one.
So it make sense only if the malloc overhead
really is a big problem there.

This is not always ->rgbBits, because there are cases where that could
be 32 but we're (legally) bound to a depth-24 pixmap. The important
thing to have match here is the actual server-side notion of depth. You
can look this up (at modest expense) from the xlib visual info if the
fbconfig has a visual. But it might not, so if not, fetch it (at
slightly greater expense) from XGetGeometry. Do this at GLX drawable
creation so you don't have to do it on the SwapBuffers path.
Apparently this fixes glx/glx-swap-singlebuffer, which is unintentional
but quite pleasant.

We don't want to require a visual for the drawable, because there exist
fbconfigs that don't correspond to any visual (say a 565 pixmap|pbuffer
config on a depth-24 display). Fortunately, we don't need one either.
Passing the visual to XCreateImage serves only to fill in the XImage's
{red,green,blue}_mask fields, which libX11 itself never uses, they exist
only for the client's convenience, and we don't care. And we already
have the drawable depth in glx_config::rgbBits. So replace the
XVisualInfo field in the drawable private with a pointer to the
glx_config.
Having done that driswCreateGCs becomes trivial, so inline it into its
caller.

Somewhat terrifyingly, we never sent this for direct contexts, which
means the server never knew the context/drawable bindings. To handle
this sanely, pull the request code up out of the indirect backend, and
rewrite the context switch path to call it as appropriate. This
attempts to preserve the existing behavior of not calling unbind() on
the context if its refcount would not drop to zero.
Of course, you can't just do this indiscriminately, because this is GLX
and extant X servers have bugs and everything is terrible. To wit:
- For 1.20.x prior to 1.20.6, you can bind a direct context once, but
the second time you try to modify the context's binding you will get
GLXBadContextTag. This includes unbinding the context. And "deleting"
the context will leak memory, because it will still appear to be
current.
- For 1.19 and earlier, glXMakeCurrent(dpy, None, ctx) should be legal
for GL 3.0+ contexts, but the server will throw BadMatch.
To guard against this, we only send the request for indirect contexts
unless the server is known good, and only mention one context at a time
in such a request; if switching between contexts, we first unbind the
old, and then bind the new. Note that the second VendorRelease() version
is to catch XFree86 4.x and Xorg [67].x, which almost certainly have the
above bugs. Other servers might report different version numbers here,
but we can't do direct rendering against them, so this should be safe.
Fixes glx-make-context, glx-multi-window-single-context and
glx-query-drawable-glx_fbconfig_id-window. Sufficiently old piglit will
regress on glx-make-glxdrawable-current (throwing BadMatch), which is
fixed by mesa/piglit!116.
We were using the current drawable of the context to name the
appropriate screen for creating the bitmaps. But one, the current
drawable can be None, and two, it can be a GLXDrawable. Passing either
one as the second argument to XCreatePixmap will throw BadDrawable. Use
the root window of the context's screen instead.

When run in optirun, applications that linked to `libGLX.so` and then
proceeded to querying Mesa for extension strings caused a SEGV in Mesa.
`glXQueryExtensionsString` was calling a chain of functions that
eventually led to `__glXQueryServerString`. This function would call
`xcb_glx_query_server_string` then `xcb_glx_query_server_string_reply`.
The latter for some unknown reason returned `NULL`. Passing this `NULL`
to `xcb_glx_query_server_string_string_length` would cause a SEGV as the
function tried to dereference it.
The reason behind the function returning `NULL` is yet to be determined,
however, simply checking that the ptr is not `NULL` resolves this. A
similar check has been added to `__glXGetString` for completeness sake,
although not immediately necessary.
In addition to that, we stumbled into a similar problem in
`AllocAndFetchScreenConfigs` which tries to access the configs to free
them if `__glXQueryServerString` fails. This, of course, SEGVs, because the
configs are yet to have been allocated. Simply continuing past the configs
if their config ptrs are `NULL` resolves this. We also switch to `calloc`
to make sure that the config ptrs are `NULL` by default, and not some
uninitialized value.
