Before this change, we had the following behaviors.
On platforms other than Windows-MSVC:
- when no build type was specified, we defaulted to Release
- when -developer-build was specified, we defaulted to Debug
- regardless of platform, unless the option was explicitly specified,
we never defaulted to -debug-and-release.
On Windows-MSVC, we always defaulted to Debug. Which is inconsistent
with the rules above.
The difference happens because CMake always sets CMAKE_BUILD_TYPE to
Debug during the first project() call when targeting the Windows-MSVC
platform.
We interpreted that as the user setting the build type, and thus we
didn't want to override what the user specified.
After this change, if we detect that it's cmake setting the build
type, we assign a build type that follows the non-Windows-MSVC rules.
This change unifies the behavior across all platforms.
Adjusted the configure help with the new reality.

is the changing of the submodule list that needs to be built in
top-level builds. It's also applicable for Qt features that lead to
extra package lookup in the unlocked subdirectories. Current approach
collects packages that were found at the previous run and skips
search of the packages that are missing. The problem is that
it also skips packages even if qt_find_package was not called at
previous run. QT_INTERNAL_PREVIOUSLY_SEARCHED_PACKAGES collects
all packages that were actually searched at the previous run

qrhi.h, qshader.h, qshaderdescription.h (and qshaderbaker.h from
shadertools; done separately) become "RHI APIs", following the concept
of QPA APIs.
Mirror completely what is done for QPA headers, but using the "rhi"
prefix for the headers. This involves updating syncqt to handle the
new category of headers. (a note on the regex: matching everything
starting with "qrhi" is not acceptable due to incorrectly matching
existing and future headers, hence specifying the four header names
explicitly)
There is going to be one difference to QPA: the documentation for
everything RHI is going to be public and part of the regular docs, not
hidden with \internal.
In addition to the header renaming and adding the comments and
documentation notes and warnings, there is one significant change
here: there is no longer a need to do API-specific includes, such as
qrhid3d11[_p].h, qrhivulkan[_p].h, etc. These are simply merged into a
single header that is then included from qrhi.h. This means that users
within Qt, and any future applications can just do #include
<rhi/qrhi.h> (or rhi/qshader.h if the QRhi stuff is not relevant), no
other headers are needed.
There are no changes to functionality in this patch. Only the
documentation is expanded, quite a lot, to eliminate all qdoc warnings
and make the generated API docs complete. An example, with a quite
extensive doc page is added as well.

was necessary aren't in the public history (Qt 4.5 already had it[1]). I
remember writing the code in 2007-2008, I just don't remember why.
On modern Linux and FreeBSD, there's no libresolv.so any more and those
symbols have been rolled up into libc.so. It's still necessary on Darwin
systems, so this commit introduces WrapResolv.
It also resolves the unity build issues relating to libresolv symbols.
