This is the first time since 5.9 that we also update `qtwebkit`.
`qtwebkit` is not maintained by Qt anymore and thus, we switch to the
community port as for example arch has done. To prevent pulling in
single patches, we just stick to the latest git version.
This commit was too aggressive in adding configure flags. Only qtbsea
needs the -no-framework flag to work correctly. Qmake will handle
everything else for us.

-----------
The above paths were before rebasing the commit onto staging,
and it'd probably be good to have someone confirm the same happens
when built on a hydra builder or other non-dtzWill machine :).
[dezgeg: added comments]
Fixes#39334
and Fixes#36729
Also, Fixes#36932 (hopefully it's still building)
(This might be able to be able to be cherry-picked to 18.03 but be
careful - chromium is extremely touchy. Probably best to wait for it
to be built successfully on Hydra a few times.)
A dependency (boost) makes use of `std::auto_ptr`, which is no longer
supported in C++17 in Clang. This change re-enables `std::auto_ptr`
capabilities.
First, closure size is reduced by including the static libraries in $out instead
of trying to move them to $dev. The Qt build system cannot handle libraries
being split between different prefixes. Previously, the static libraries were
moved into $dev and the shared libraries were symlinked from $out to $dev to
fool the build system. However, this causes $dev to be retained at
runtime. Instead, we now keep the static libraries in $out. Fortunately, the
static libraries are not very large anyway.
Second, we build with QT_NO_DEBUG defined unless debugging is enabled. This
causes some assertions to be removed; when assertions are included, they pull
paths from $dev into the runtime closure by using the __FILE__ macro. We also
now patch qtbase to remove even more assertions when QT_NO_DEBUG is defined.
