Merge lang/qt5-qml and x11-toolkits/qt5-quick into x11-toolkits/qt5-declarative

- There was no obvious reason to split these ports, and it makes
  porting simpler; the set of ports using either mostly coincided.

Switch to xorgproto instead of individual packages

Upstream used to distribute protocol headers as separate packages, but has
decided to merge those to a common package, named xorgproto.  This update
tracks that change.

* Add a new port, x11/xorgproto, with are protocol headers for xorg.
* Hook the new protocol port to the build and to infrastructure in
  bsd.xorg.mk.
* Update all ports with a dependency on any of the old *proto packages to
  instead depend on xorgproto.  Bump portrevision.
* Delete the old *proto packages, update MOVED.

Fix www/qt5-webengine to build on ARM

Fix build for aarch64 and armv7. Chasing Chromium patches into Qt5-Webengine
is a slow process. Multiple build successes have been reported with
this patch, although I have not been able to try it myself.

I hope I got all the attributions right.

Update the Qt5 ports to 5.10.1.

The work was done by tcberner and myself, with thanks to antoine for the
exp-run.

Not a lot to report compared to other Qt5 updates:
* net/qt5-network is still broken with LibreSSL. I said this in a commit
  message ages ago but it bears repeating: upstream is open to adding support
  for LibreSSL, but someone needs to step up to maintain it upstream, otherwise
  things will continue to be broken all the time.
* www/qt5-webengine is a huge monster that is terrible to update, just like
  www/chromium itself is. We (kde@) have decided to keep using the 5.9 series
  for the time being, as it should be compatible with the rest of Qt anyway. It
  was updated to 5.9.5, the latest 5.9 release at the time of writing.

Fix permissions in installed Qt5 header files

For the qt5-* ports bsd.qt.mk sets EXTRACT_AFTER_ARGS, and
thereby does not get the normal default value of
      --no-same-owner --no-same-permissions
passed when extracting. This lead to for example header files
being installed (i.e. copied), with permissions group write
permissions.

Manually append that to the bsd.qt.mk shenanigans (also do the
same in www/qt5-webchannel, which opts out of the bsd.qt.mk value)

Update Qt5 ports to 5.9.3.

This took quite a lot of time because Qt's own build system underwent
several changes in 5.8.0 that took a while to adapt to.

And, of course, qt5-webengine is a behemoth that we need to patch like crazy
due to its bundling of Chromium. In fact, most of the Chromium patches in
qt5-webengine have been imported with no changes from www/chromium@433510
("www/chromium: update to 56.0.2924.87").

New port: accessibility/qt5-speech

Bigger changes to Qt5 ports we had to make:
- Qt now allows using a configure.json file to define configuration options
  and specify configuration checks that can be done when qmake is invoked.

Update devel/protobuf to 3.5.0

Remove redundant distinfo.

We currently have WebEngine's distinfo information in devel/qt5/distinfo.

Reported by:	tcberner

New port: www/qt5-webengine.

Qt WebEngine provides functionality for rendering regions of dynamic web
content. In other words, this is Chromium's Blink web engine and parts of
Chromium's content layer wrapped by Qt. Qt WebKit is deprecated upstream, and
WebEngine is the future.

This port has been in the works for a very long time, with contributions by
myself, tcberner, Adriaan de Groot and Marie Loise Nolden.

Since most of the port is just a large part of Chromium's code base, this means
sharing some of the pain www/chromium goes through by having to patch a ton of
files. We cannot share the exact same patches because this version of Qt
WebEngine is based on an older Chromium release.

I have verified that the port works, but it is possible that many things are
still wrong or missing, so bug reports are encouraged.
