Don't advertise native functions in public API guides.  Don't list
primary selection access as most notable new feature.  Don't have
different levels of abstraction among selection helper functions.  Don't
forget to take credit.

Related to #1056.

29a75ab09d X11: Add native access to primary selection
This adds the native access functions glfwSetX11SelectionString and
glfwGetX11SelectionString under GLFW_EXPOSE_NATIVE_X11.  They are
similar to glfwSetClipboardString and glfwGetClipboardString but operate
on the PRIMARY selection.

The primary selection is widely used in X11, and so seems important to
support.  Primary selection is mostly an X11-specific thing, hence it's
exposed as an X11 native interface.

Fixes #894.
Closes #1056.

6a65341e14 X11: Fix multiple issues in XDND support
The code blindly expected UTF8_STRING for files.  It did not downgrade
based on source protocol version.  It did not handle hostnames in
text/uri-list data.  It did not specify the source time stamp when
converting the selection.  It did not search the XdndTypeList when
necessary.  It did not ignore sources that specified invalid versions.

While better, this is still not fully conformant.  Hostnames are not
validated and it does not guard against source crashes.

Fixes #968.

5ae781586f X11: Handle Selection* events despite NULL window
X11 event processing currently discards events that can not be mapped to
a current GLFW window.  However, this breaks clipboard functionality by
failing to respond to SelectionRequest and SelectionClear events.

This commit moves processing of these important clipboard events to
before the NULL window test so that they are always considered.

797ee8d8e3 Move all cursor positioning to platform code
Due to Wayland, shared code cannot rely on cursor positioning being
supported by the underlying platform.

This implicitly fixes #617 as it moves cursor centering into
_glfwPlatformSetCursorMode, thus separating it from the stale value of
_glfw.cursorWindow.

527952102a Fixed filtering of events duplicated by XIM.
Duplicate events cannot be filtered by the return value of XFilterEvent,
as that discards dead key events on some IMs (ibus), nor by its inverse,
as that discards all key events on other IMs (?).  This solution is
based on the workaround in SDL2 and takes advantage of the identical
time of the duplicate events.

a75e43ef22 Moved _NET_REQUEST_FRAME_EXTENTS to frame query.
The request is now only made when necessary and times out after 500ms.
This breaks our end of the protocol to work around broken
implementations at the other end.

It uses the GLFW timer instead of select, as select is not guaranteed to
update the timeout with the time remaining and a single select is not
sufficient as other events may be incoming.

Fixes #368 (mostly).
Fixes #429 (mostly).

641761ddb0 Changed state attribs to direct access.
Changed the window states (focused, iconified and visible) to query the
system directly.

THIS IS A BREAKING CHANGE, although a fairly obscure one.  It affects
applications that both care about telling actual key events from
synthetic ones, and are implemented in a non-self-synchronizing way, and
that poll the GLFW_FOCUSED window attribute instead of using the window
focus callback.

If you maintain one of these, please feel free to drop me an email and
I'll help any way I can to transition your application to 3.1.

Fixes #189.
Fixes #204.
