The mentioned README file has never been very trustworthy and
after 863c688749 it has become
very minimal - it doesn't contain anything that is not already
present in "configure --help" and enforced by the configure
process. Furthermore, the warning was XCB specific, but Qt
supports also other QPA plugins on linux.

The only reason why we bundled this library ~6 years ago was because
it was not available on distributions that we supported at the time,
but library was a hard dependency for XCB plugin. See:
2122e731ab
Later more and more projects started to depend on it (compose input
context plugin, libinput, mir, wayland). The configuration had become
too complex, because some projects used bundled and some used the
version from the system.
Having libxkbcommon in 3rdparty sources is not necessary anymore, after
RHEL 6.6 was removed from the list of supported platforms for Qt 5.12.
Ubuntu 16.04 - 0.5.0
Ubuntu 18.04 - 0.8.0
openSUSE 42.3 - 0.6.1
RHEL-7.4 - 0.7.1
This will also simplify further development, e.g. QTBUG-42181
Bumped the minimal required version 0.4.1 -> 0.5.0.
The patch also contains a code marked with "TRANSITION HACK", which
is temporary needed so we can update the dependent wayland module.

PCRE1 is going towards EOL. PCRE2 is the way forward in terms
of new features, performance, and security improvements. The
APIs that QRegularExpression uses are similar so the required
modifications aren't extensive.
The biggest difference comes to JIT-compiling of the pattern.
In PCRE1, JIT-compiling did not modify the processed PCRE pattern,
but returned a new chunk of data.
This allowed multiple threads to keep matching using the same
processed data and NULL for the JIT data, until a thread
JIT-compiled and atomically set the shared JIT data to the results
of the compilation.
In PCRE2, JIT-compiling _modifies_ the processed PCRE pattern in a
way that it's thread unsafe [1]; the results of JIT-compilation
are stored somewhere inside the processed pattern.
This means the above approach cannot work -- a thread may be
matching while another one JIT-compiles, causing a data race.
While waiting for better workarounds from upstream, employ a
read/write mutex to protect the matching from JIT-compilation.

it is sometimes desirable to override values from the mkspec without
modifying (or wrapping) the spec itself. linux distributors do this on a

so far, we'd pick up CFLAGS, etc. from the environment, in a somewhat
autoconf-like fashion. however, over time, this approach proved
problematic: the concept doesn't mix particularly well with mkspecs to
start with, is unexpected (and therefore causes frustration), and
doesn't mix well with cross-building (at least the way it was realized).
ironically, it was implemented this way (quite a while ago) upon my
explicit request ...
the new mechanism uses explicit variable manipulations on the configure
command line, just like qmake itself understands. as it happens, this is
again quite similar to autoconf-generated configure scripts. however,
this time around we don't pretend to be actually autoconf-like, so we
also don't try to map any variable names (some of which have different
semantics anyway).
this commit also eliminates the last use of the QMakeVar() function,
so delete it and the underlying infrastructure.
