GLFW did not restore the previous Xlib error handler when removing its
own, instead resetting to the default handler.
This commit saves and restores the previous error handler.
None of this is thread-safe or could ever be.
Fixes#2108
(cherry picked from commit 26920a1a38)
The joystick code did not distinguish between the allocation status of
the GLFW joystick object and whether it is connection to an OS level
joystick object.
These are now tracked separately.

This is adapted to 3.3-stable from
2c204ab52e and
fd7e737216.
The modifier bits for lock keys were only set when the corresponding key
was reported as held down or latched, but not when it was released and
locked.

This avoids glfwCreateWindow emitting GLFW_PLATFORM_ERROR on Wayland
because shared code was calling unimplemented or unavailable platform
functions during final setup.
It also makes it consistent with the final setup of full screen windows.
This is adapted to 3.3-stable from

The code assumed that at least some data would be received via the INCR
mechanism and that, as a result, the string buffer would be allocated.
Bug found by Clang static analysis.

The clipboard string should not be freed on SelectionClear. The user
may have received it from glfwGetClipboardString and it should remain
valid until the next call to a public clipboard string function.

This adds support for file path drop events in text/uri-list format.
It is based on work by Pilzschaf in #2040.
Closes#2040
(cherry picked from commit 4cb36872a5)
The Wayland backend was the only one where half the window and input
related code was in the init module. As those bits want to share more
utility code with the window module, the interface between them grows.
To prevent that, this gathers nearly all window and input related code
into the window module.
This is adapted to 3.3-stable from
b7a3af9b79.
The code assumed that all data offers were selections that supported
plaintext UTF-8.
The initial data offer events are now handled almost tolerably. Only
selection data offers are used for clipboard string and only if they
provide plaintext UTF-8. Drag and drop data offers are now rejected as
soon as they enter a surface.

The string pointer used to write the contents of our clipboard data
offer was never updated, causing it to repeat parts of the beginning of
the string until the correct number of bytes had been written.

If data source creation fails, the string containing the data for it
would be freed a second time during termination.

Passing any part of the result of glfwGetClipboardString to
glfwSetClipboardString would result in, at best, a use-after-free error.
(cherry picked from commit 9c95cfb9f1)
Emitting an error for one specific type of failure in retrieving the
correct name for a display is not very useful, especially when
initialization is otherwise unaffected.
There should be a path for information like that but this isn't it.
Fixes#1791
(cherry picked from commit 955fbd9d26)
Operations that take an instance handle should be passed the handle of
whatever module we are inside instead of blindly passing the handle of
the executable.
This commit makes GLFW retrieve its own instance on initialization.
This makes the most difference for window classes, which are
per-instance. Using the executable instance led to name conflicts if
there were several copies of GLFW in a single process.
Note that having this is still a bad idea unless you know what things to
avoid, and those things are mostly platform-specific. This is partly
because the library wasn't designed for it and partly because it needs
to save, update and restore various per-process and per-session settings
like current context and video mode.
However, multiple simultaneous copies of GLFW in a single Win32 process
should now at least initialize, like is already the case on other
platforms.

There were no checks for invalid values or asserts for all invalid NULL

The bug described in 03cfe957e7 was
already present for another key where modifiers changes its scancode.
Related to #1993
(cherry picked from commit 8d9231fe5e)
Alt+PrtSc emits a different scancode than just PrtSc. Since the GLFW
API assumes each key corresponds to only one scancode, this cannot be
added to the keycodes array.
Instead we replace the scancode at the point of entry.
