This is important when AVX is enabled, which makes the VMOVQ load and
the VPMOVZXBW instruction be combined into a single VPMOVZXBW with
direct memory access. This is guaranteed to only read 8 bytes, so it's
safe even close to the end of a page. Clang and ICC do combine the
instructions like we want and I have filed a request for GCC to do so
too[1].
AVX was first introduced in 2011, so plenty of computers today would
benefit from this.

egl-x11 is used in two places:
- the eglfs-x11 plugin, which has a hard dependency on xcb-xlib
- the xcb-egl plugin, which has a soft dependency on xcb-xlib
that means that the egl-x11 configure test needs to be untangled from
xcb, and that eglfs-x11 should be a separate feature with a proper
dependency declaration.
when the plugins that need egl-x11 are not built, it also makes no sense
to build the respective integration in the egl_support module (even if
it's possible to coax it into building), so adjust things accordingly.

we already knew the dependencies (as they are declared in the json
files), but failed to export them in any way, which made linking against
statically built external deps which have deps in turn fail (unless the
project happened to pull in the dep anyway, as is the case with qtcore +
zlib).
the previous assumption was that the USE-able library objects would be
self-contained, but that is conceptually unclean. instead, properly
export the raw dependencies and resolve them only in qmake_use.prf.
note that pkg-config produces self-contained output, so we need to
actively subtract the dependencies we know.

Previous implementation relies on the fact that the only text document
with height -1 can grow or shrink vertically, and, hence, a bounding
rect should be updated under this circumstances. But method
QTextDocument::setPageSize might set a height different from -1, and
QGraphicsTextItem will be growing/shrinking vertically as well.
So, we have to relax condition to cover all use cases. Bounding rect
will be updated if new size is different from current size. This also
doesn't affect performance.

While the user is entering the password, the string variable that
stores the value might have to reallocate its content from time
to time (when the string needs to grow beyond its current capacity).
When the reallocation happens, the old buffer is freed, but its
data is not zeroed-out. This means that a QLineEdit that serves as
a password input field might leak chunks of the password during
its lifetime, and the leaks will persist after its destruction.
Since the QLineEdit can not control the behavior of the QString
it uses to store the entered value, the only thing it can do is try
to make the reallocations rare.
This patch reserves the space for 30 characters for the string which
stores the QLineEdit value when said QLineEdit is used for password
input. This is enough to make sure no reallocation happens in
majority of cases as barely anyone uses passwords longer than 30
characters.
[ChangeLog][QtWidgets][QWidgetLineControl/security] Preallocate a buffer
for the string that contains the entered value when the QLineEdit serves
as a password input field to minimize reallocations.

note that pkg-config is a tad stupid: it won't tell us if the package is
built statically, but one needs to explicitly ask it to output
transitive deps for static packages. we can do that, as we resolve the
pkg-config output to actual libraries, so we know if they are static.
always asking it would print the transitive deps also if we found a
dynamically linked library, which would inappropriately extend the link
interface. the latter actually happens on windows (because we can't
easily tell apart real static libs from import libs), but that doesn't
matter, as under windows, the linker transitively resolves dlls anyway.
