Separate them from the qutfcodec, so that the codec
can later on be moved out of Qt Core.
Fix the QUtf methods to take qsizetype instead of int
for length arguments.
This also makes it possible to not build QTextCodec into
the bootstrap lib anymore.

Reading of Cbor streams is substantially more complicated than writing
as it requires float16 support. When writing Cbor, we can just choose to
always write 32bit floats, even if we could compress the numbers into
16 bits.
We need Cbor writing in the bootstrap library, but we cannot easily add
float16 support.
Furthermore, Cbor reading is required for plugin support, but not Cbor
writing. It might make sense for some users to build a custom Qt with
Cbor writing disabled.
Therefore, provide two features, cborstreamreader and cborstreamwriter,
split up the code in cborstream.{h|cpp} into several files, and enable
Cbor writing in the bootstrap library.

Using wrappers for these macros is problematic when for example passing the
-frewrite-includes flag to preprocess sources before shipping off to distcc
or Icecream. It will also start producing warnings when compilers implement
http://eel.is/c++draft/cpp.cond#7.sentence-2. See for example
https://reviews.llvm.org/D49091
Both https://clang.llvm.org/docs/LanguageExtensions.html and the SD-6 document at
https://isocpp.org/std/standing-documents/sd-6-sg10-feature-test-recommendations
recommend defining '__has_foo(x) 0' as a fallback for compilers without the
macros, so that's what we go for.

One of our compilers for emscripten coerces all signaling NaNs to
quiet ones, so won't do any actual signaling. Anyone relying on them
to do so shall be disappointed, so it's better that they know about it
at compile-time - or, at least, have the ability to find it out.
Put the signaling NaN producers (and remaining (test) code using them)
under the control of a feature that's disabled when numeric_limits
claims double has no signaling NaN. Assume the bootstrap library
doesn't need signaling NaNs. Sadly, until C++20 <bit>, there's no
contexpr way to test that alleged signalling and quiet NaNs are
actually distinct.
Added some auto-tests for signaling NaN, including that it's distinct
from quiet NaN. Any platform on which the last fails should disable
this feature.

[ChangeLog][RCC] RCC now supports compressing content using the
Zstandard (https://zstd.net) algorithm. Compared to zlib, it compresses
better for the same CPU time, so this algorithm is the default. To go
back to the previous algorithm, pass command-line option
--compress-algo=zlib. Compression levels range from 1 (fastest, least
compression) to 19 (slowest, best compression). Level 0 tells the
library to choose an implementation-defined default.
\
The default compression level is "heuristic" (level -1): under this
mode, RCC will attempt a very fast compression (level 1) and check if
the file was sufficiently compressed. If it was, then RCC will compress
again using an implementation-defined level.
The following are the 4 biggest files we store as resources in qtbase:
Orig Size Name
2197605 src/corelib/mimetypes/mime/packages/freedesktop.org.xml
2462423 tests/auto/corelib/tools/qchar/data/NormalizationTest.txt
6878748 tests/auto/other/qcomplextext/data/BidiCharacterTest.txt
7959972 tests/auto/other/qcomplextext/data/BidiTest.txt
The current RCC (zlib, level -1 "default" and level 9), produces for
those files:
L(-1) Compr. L9 Compr. Decomp.
Name Ratio CPU time Ratio CPU time CPU time
BidiCharacterTest.txt 16.9:1 106.1ms 17.2:1 789.3ms 5.1ms
BidiTest.txt 6.3:1 228.0ms 6.1:1 1646.3ms 10.9ms
freedesktop.org.xml 7.0:1 17.5ms 7.1:1 53.6ms 2.6ms
NormalizationTest.txt 5.8:1 41.2ms 5.9:1 256.4ms 3.4ms
Zstandard produces the following for levels 1 ("check"), 14 ("store")
and 19 ("best"):
L1 Compr. L14 Compr. L19 Compr. Decomp
Name Ratio time Ratio time Ratio CPU time time
BidiCharacterTest.txt 15.8:1 8.0ms 26.1:1 168.9ms 49.2:1 2504.7ms 3.8ms
BidiTest.txt 8.2:1 17.0ms 8.7:1 323.9ms 14.9:1 1700.9ms 12.1ms
freedesktop.org.xml 6.7:1 4.0ms 8.7:1 63.3ms 9.5:1 642.5ms 1.7ms
NormalizationTest.txt 5.7:1 5.0ms 7.5:1 54.0ms 8.4:1 447.3ms 3.0ms
This shows use of zstd at the default RCC level settings always produce
smaller outputs compared to the current zlib-based defaults, with
roughly 50% CPU increase. It also produces better results at less CPU
time than the best compression zlib has to offer.
More importantly, the decompression time reduces in all cases (the
numbers listed are for max compression, with slightly better results for
the defaults).
For the sake of comparison, the same files compressed with libxz at
levels 3 and 6:
Level 3 Level 6 Decompr.
Name Ratio CPU Ratio CPU time
BidiCharacterTest.txt 28.5:1 109.1ms 42.9:1 1390.5ms 16.7ms
BidiTest.txt 10.7:1 281.0ms 18.4:1 2333.1ms 43.6ms
freedesktop.org.xml 9.1:1 62.0ms 10.2:1 499.1ms 12.0ms
NormalizationTest.txt 10.2:1 75.5ms 13.2:1 417.6ms 14.7ms
LZMA at level 3 consumes roughly the same CPU time as Zstd at level 14
and produces incrementally smaller results, but the decompression time
increases considerably. It's not a good trade-off for the Qt resource
system.

[ChangeLog][Important Behavior Changes] The Qt resource system now
supports compressing content using the Zstandard (https://zstd.net)
algorithm. Compared to zlib, it compresses better for the same CPU time,
so this algorithm is the default. QResource::isCompressed() returns true
for either compression algorithm. Use QResource::compressionAlgorithm()
to find out which algorithm to decompress. QFile will automatically
decompress using the correct algorithm.

For keys, QSettings escapes all characters outside of [-a-zA-Z0-9_.]
by using percent encoding, and changes '/' to '\'. That is,
settings.setValue("qt.*", true)
will be written to an .ini file as
qt.%2A=true
This means that QSettings can not be used to write general-purpose
qtlogging.ini files. Fix this by applying the reverse transformation
method from QSettings when reading in the .ini file.

Some Linux libc (I'm looking at you, Bionic) use the system call but
don't expose it to userspace. We could use syscall() to make the system
call, but instead I decided to penalize users of those libc by not
having the feature.
It's probably a good thing, since there were likely to be more problems
with Android anyway and I don't have an environment to debug.

The thing we are looking for in qstandardpaths_unix.cpp is
regularexpression, not QT_BOOTSTRAPPED.

Apparently it's all meant to be in alphabetic order by feature name
(except for where it isn't). So move my new addition to it to where
that would put it, re-order everything else to follow that rule and
add a comment documenting it.

It was being mis-described in some places by a QT_CONFIG(timezone)
test, replacing older QT_BOOTSTRAPPED checks; but it has no time-zone
dependency (until 5.10). So make it a separate feature in its own
right.
It turns out QAbstractSpinBox's presumed dependency on datetimeedit
was an illusion caused by use of QDATETIMEEDIT_*_MIN symbols actually
provided by datetimeparser; so remove its bogus dependency.

This system call, new in Linux 4.11, gives us the file birth time. It's
also extensible, representing the fourth generation of stat(2) on Linux
(the original sys_stat(), sys_newstat(), sys_stat64() and now
sys_statx()), not to be confused with glibc's __xstat function, which
wraps a call to stat64. Anyway, the new one is designed to be extensible.
Now we get birth times on ext[34] on Linux too:

It's not supported in any other filesystems I have (Linux sources show
xfs has the feature too). Even on ext4, it depends on whether the
filesystem was created with 256-byte inodes, which my /boot fs wasn't.

The use as in the code:
futimesat(fd, NULL, &tv)
is not documented to work. The file descriptor should be a directory's
one, not an open file (though the Linux source code seems to handle that
case). This call was done as a fallback to futimes, so it's very
unlikely a system would have futimesat and not futimes.
Both the Linux and the FreeBSD man pages say it's deprecated anyway.

The renameat2(2) Linux system call, new in 3.16, allows for the atomic
renaming of a file if and only if it won't clobber an existing
file. None of the Linux libcs have enabled this syscall as an API, so we
use syscall(3) to place the call.
If your libc has SYS_renameat2 but your kernel doesn't support it, we'll
keep issuing the unknown syscall, every time. Users in that situation
should upgrade (3.16 is from 2014).
On Darwin, there's a similar renameatx_np (guessing "np" stands for
"non-portable"). I haven't found anything similar on the other BSDs.

The getentropy function, first found in OpenBSD, is present in glibc
since version 2.25 and Bionic since Android 6.0 and NDK r11. It uses the
Linux 3.17 getrandom system call. Unlike glibc's getrandom() wrapper,
the glibc implementation of getentropy() function is not a POSIX thread
cancellation point, so we prefer to use that even though we have to
break the reading into 256-byte blocks.
The big advantage is that these functions work even in the absence of a
/dev/urandom device node, in addition to a few cycles shaved off by not
having to open a file descriptor and close it at exit. What's more, the
glibc implementation blocks until entropy is available on early boot, so
we don't have to worry about a failure mode. The Bionic implementation
will fall back by itself to /dev/urandom and, failing that, gathering
entropy from elsewhere in the system in a way it cannot fail either.
uClibc has a wrapper to getrandom(2) but no getentropy(3). MUSL has
neither.

GCC didn't support it until version 5 or 6, so add configure tests for
both <random> and <sys/auxv.h>. Normally I'd say "upgrade", but this is
too low-level and important a feature.
There's a good chance that all our supported compilers have <random>
anyway. As for <sys/auxv.h>, it's present on Glibc, Bionic and MUSL, but
I don't see it in uClibc (AT_RANDOM is a Linux-specific feature).
