InputText: Fix using a combination of _CallbackResize + _EnterReturnsTrue + lack of persisting user storage. (#3009)

Amend 24ff2598 (#2006, #1443, #1008)

Canceling text input with [esc] key uses stb_textedit facilities to restore original value. This makes restoration undoable using hotkeys.

Fixes #3008.

When testing for the presence of the ImGuiWindowFlags_NoBringToFrontOnFocus flag we test both the focused/clicked window (which could be a child window) and the root window.

Focus: Reworking FocusWindow() so in Docking branch we can fix CTRL+Tab being out of order on Docked windows because WindowsFocusOreder is poorly maintained.

When merging this and d9bca0d8 in Docking we'll replace two ocurrences of RootWindow with RootWindowDockStop.

Internals: Update ->RootWindow and other links before applying the SetNextWindowXXX stuff. This is so FocusWindow() can always assume that ->RootWindow != NULL.

Nav: Fixed a bug where the initial CTRL-Tab press while in a child window sometimes selected the current root window instead of always selecting the previous root window. (#787)

InputTextMultiline: Provide label to BeginChildEx so internal window name hold a little more context.

Use a private splitter in columns, paving way for removal of obsolete ImDrawList::Channels* functions.

Filesystem functions perfectly work for Emscripten platform. This changes remove extra changes added by #2734.
You can still disable filesystem functions by defining IMGUI_DISABLE_FILE_FUNCTIONS.

Most are comments. Fix menu bar clipping: 07ff47bf

Tooltip: Testing DragDropWithinSourceOrTarget in BeginTooltipEx() instead of just BeginTooltip() - feel this was an overlook. Added tooltip flags instead of using bool.

(dropped TreeNode_NoIndent flag from todo, as it feels unnecessary)

Backends: OpenGL2: Explicitly backup, setup and restore GL_TEXTURE_ENV to increase compatibility with legacy OpenGL applications. (#3000)

Tweak default max error value, Changelog, comments, path-fast for 12 segments circles, made LUT store ImU8

+ ArrowButtonEx() internal bits.

Internals: Standard math functions default redirection uses a define instead of an extraneous inline function call

Neither GLFW nor SDL can correctly report the key release in every cases (e.g. when using Win+V) causing problems with some widgets. The next release of GLFW (3.4+) will have a fix for it. However since it is both difficult and discouraged to make use of this key for Windows application anyway, we just hide it. (#2976)

Backends: Win32: Added support for io.KeySuper (Windows key) for consistency with other backends. (#2976)

Even if realistically it is difficult to make good use of under Windows.
+ Style editor: Use a more explicit form of RadioButton() to avoid being depending on underlying flags type. (#2983)

STB sprintf allows extra formats like %b or %$d. If ImGui is configured
to use STB sprintf, it generates warnings with GCC and clang when using
such formats because it keeps applying default printf-style warnings.
This commit disables printf-style warnings when using STB sprintf.

Since the printf-style warnings are defined in imgui.h based on the
compiler, IMGUI_USE_STB_SPRINTF can't just be defined in the cpp file
anymore and it's been moved as a proper config in imconfig.h.

Backends: GLFW: inhibit error callback when creating cursors because X11 setups may be missing them + comment (#2980)

Fix zealous warnings + Internals: Renamed members from XxxxID to XxxxxId to be more consistent with rest of the codebase (still some inconsistency left that are harder to fix)

Focus, Nav: Merged bits from RangeSelect features to enable early manipulation of focus scope for styling purpose.

FocusScopeId is tracked by nav scoring/request and stored in result.
It's all rather WIP and we should reorganize the SetNavIDXXX functions fiasco at some point (soon?).
Didn't separate FocusScope from SelectionScope for now, will re-investigate this later, this is the minimum commit to be able to do some styling.

Backends: Win32: Added support for #define IMGUI_IMPL_WIN32_DISABLE_GAMEPAD and IMGUI_IMPL_WIN32_DISABLE_LINKING_XINPUT. (#2716)

Internals: Begin tries to setup WindowTemp/DC members in same order as their declaration. Readme: remove Coverity banner (PVS is better)
