Doc: exclude snippets subdir.

This fixes the qdoc warning:
doc/snippets/code/src_corelib_tools_qcommandlineparser.cpp:85: warning: Hostile character 0x24 in C++ source
and doesn't lead to any loss in the generated documentation.

Snippets are not "source files" for qdoc, they are included by source files.

qdoc: Restore support for output in one directory

The basic functionality is working. Add these lines
to qt-html-templates-offline.qdocconf, or add them
to the online version:

HTML.nosubdirs            = "true"
HTML.outputsubdir         = "html"

Before it opens a .html file for writing, it tests
whether the file alread exists. If so, it writes an
error message, e.g.:

...platform-notes.qdoc:140: error: HTML file already exists;
overwriting .../doc/html/platform-notes-windows.html

There are currently nearly 100 files being overwritten for Qt5.

Pass Xcb errors through the native event filter

So far only the xcb plugin is able to handle xcb errors and there is no
way for an application to get access to the errors even if the app is
using xcb directly.

This means Qt is filtering out all xcb errors which are relevant to the
app and at the same time the xcb plugin is getting spammed with errors
it did not cause and which are logged with a qWarning.

By passing the error event through the native event filter an app can
filter out all errors it knows to have caused.

Introduce QWheelEvent::Phase (Begin, Changed, Ended)

Some platforms (read: OS X) send wheel events without delta to indicate
that scrolling is about to start or has ended. Currently, Qt simply
ignores wheel events that have no delta. This change introduces a new
QWheelEvent attribute that specifies the phase, and makes it possible
to receive the special wheel events in started/ended phases. These
events are required for implementing correctly behaving transient
scrollbars.
