Docking: Tweaked tooltip on tabs so they don't show immediately when holding and releasing a tab (using HoveredIdNotActiveTimer) + Minor refactor + Removed legacy .ini parsing.

Merge branch 'master' into viewport ...

# Conflicts:
#	imgui.cpp

Fixed OpenGL texture loading example in comment + Discourse link to root of discourse

Misc comments improvements

Comments in demo and opengl code + Internals: Added HoveredIdNotActiveTimer tracking hovering time unless the item is active, which is a commonly useful pattern.

Added DockSpaceOverViewport() call, not sure about this because of the menu bar limitation. (#2109)

Docking: Fixed not saving .ini file correct if DockingEnable flag is cleared. (#2109)

Viewport, Docking: Fixed incorrectly setting the ImGuiViewportFlags_NoInputs flag, affecting split docking node. (#2109)

Added ImGuiWindowFlags_NoMouseInputs which is basically the old ImGuiWindowFlags_NoInputs (essentially we have renamed ImGuiWindowFlags_NoInputs to ImGuiWindowFlags_NoMouseInputs). Made the new ImGuiWindowFlags_NoInputs encompass both NoMouseInputs+NoNav, which is consistent with its description. (#1660, #787)

Window: Added ImGuiWindowFlags_NoBackground flag for consistency and to ease creating new flag combinations. Added ImGuiWindowFlags_NoDecoration helper flag which is essentially NoTitleBar+NoResize+NoScrollbar+NoCollapse. (#1660)

Viewport: Exposed GetOverlayDrawList(ImGuiViewport* viewport) in public API. (#1542, #1660, #1878, etc.)

Revert using wchar_t functions (9cf94d5 + 2eaf5b0). Big mistake, wchar_t is not guaranteed to be 16-bits.

Tests: Added imgui-test engine hooks (experimental).

Docking: Fixed Modal window from being dockable.

RenderText(), InputTextMultiline(): Optimization for large text by using memchr, wmemchr, wcschr when appropriate.

Renamed misc/stl/imgui_stl.h,.cpp to misc/cpp/imgui_stdlib.h in prevision for other files.(#2035, #2096) ...

Added misc/README file.

Shutdown: Unlock font atlas before destroying context, so we can destroy a context between NewFrame and EndFrame if we wait (facilitate main loop structures). Internals: GetWindowScrollMaxX(), GetWindowScrollMaxY()

Merge branch 'viewport' into docking. 15ec78e Fixes the update of title buffer when docked in a leaf dock node with a single window. Added comment about overwriting DockIsActive in DockNodeUpdate(). ...

# Conflicts:

Internal: Moved stored window name update code to the first_begin_of_the_frame block. This will be useful in the Docking branch.

TextUnformatted: Using memchr(), fixed not properly testing for text_end bound + comments. ...

Internals: Added ImStreolRange() + used in LogRenderedText() + comments.

ImGuiTextBuffer: Avoid heap allocation when empty.

Comments + internal using Tab Stop terminology (ImGuiItemFlags_NoTabStop instead of !ImGuiItemFlags_AllowKeyboardFocus)

Viewport: Added ImGuiConfigFlags_ViewportsDecoration to re-enable platform decoration (#1542)
