cmake: Don't use bundled stdint.h for recent MSVC versions.
msinttypes: Update to latest version.
msinttypes: Remove stdbool.h

Not part of msinttypes and never used by us.
cli: Ensure variable is initialized.
Avoid unsafe cast.
cmake: Dump a message for each DirectX API found.
Remove githalytics.com snippet from the readme.

Doesn't do anything useful, now that github is serving the URL as a
static image from *.githubusercontent.com , and GitHub now provides some
stats.
tracediff: Don't crash if less is not present.
eglretrace: Support GL_OES_surfaceless_context by creating a dummy drawable.

Should fix issue #248.
qapitrace: issue #218 crashes on glPopDebugGroup

Problem:
dereferencing a NULL pointer.

Reason:
As mentioned in the issue description, a glPushDebugGroup and
glPopDebugGroup pair were in two different frames. The
TraceLoader:fetchFrameContents() function assumes they're in the
same frame and starts a new "groups" stack for each frame fetch.
On encountering a CALL_FLAG_MARKER_POP call, does

    groups.top()->finishedAddingChildren();

when in fact groups is empty and is dereferencing a NULL pointer.

In the other sample trace (sample-effects.trace) all glPush/Pop pairs
were in the same frame but one frame had an extra glPopDebugGroup
causing the same error.

Fix:
Add a groups.count() check before dereferencing groups.top()

Caveats:
Any unpaired glPopDebugGroup calls will be listed as regular gl calls.
Any unpaired glPushDebugGroup calls will end with the frame end.

Tested both sample crash traces; they no longer crash.
(apitrace-tests doesn't apply for testing this fix)

qapitrace: arrow-key selected Call is obstructed

If the Frame at the bottom of the current view is expanded and
the down arrow-key is used to select the first Call in the Frame
then the Details View window that pops up obstructs the Call.

NOTE: If the first Call is instead selected with a mouse-click
      then the Call appropriately scrolls into view

Not a big deal but disconcerting.

DIRECTIONS
1) Select and expand the Frame at the bottom of the current view
2) Use the down arrow-key to move to the first Call in the Frame

FIX
In selection callback for Call (MainWindow::callItemSelected) add
    m_ui.callView->scrollTo(index)
after the Details View window is shown

TESTING
Manual testing.

Tag a new release 5.0.

There are still many outstanding patches / pull requests that deserve to
be in this release.  But instead of delaying a release any further, I'll
simply make a new minor release when I get around to go through these.

Fixes issue #239.
cmake: Fix some spurious copy'n'paste code in inject module.

Which was causing ninja-build to issue a warning.
dxgiretrace: Ensure checker pattern initialisation constants are unsigned.

To silence recent gcc version.
thirdparty/less: Remove.

I doubt any Windows user is relying on the bundled less.  I haven't used
it myself as much as I imagined.  And one can always install it
separately.
