Edward Welbourne 4bd6cd1992 Featurize support for signaling NaN
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.

Thiago Macieira 65f9646583 Fix QCborStreamReader not flushing QIODevices due to internal buffering
When successfully finishing a parse, it's reasonable to expect that the
QIODevice was advanced to the end of the input data.

[ChangeLog][QtCore][QCborStreamReader] Fixed a bug that caused the
QIODevice that the data was being read from not to show the entire CBOR
message as consumed. This allows the user to consume data that may
follow the CBOR payload.

Edward Welbourne 779a73762d Fully support operator[] on QCborValue and QCborValueRef
Added operator[] to QCborValueRef and mutating operator[] both there
and in QCborValue.  If the value (referenced) is not a container, it
is replaced with a map and a reference into the result is returned.
If the value is an array and the key is a string, negative, or more
than 0xffff, the array is first converted to a map.

Edward Welbourne bc099f33dd Support QCborMap::operator[] taking a string literal
Use a template on the size of the char[], as suggested by Ville
Voutilainen.  This resolves ambiguity about whether such look-ups
should be done via QString or QCborValue (not that it would have made
any difference).

When we come to add mutating indexing of QCborValue, chained
dereferences like map[i][j][k] need to stay in operator[] const
throughout, to avoid detaching intermediates to create references into
them due to using the mutating operator[] on the earlier dereference's
return.  So const-qualify the QCborValue operator[] const variants at
the same time, to match those of QCborValue itself.

Thiago Macieira 7cb5b324f0 QCborValue: move the toDiagnosticNotation() function to its own file
If we ever need to add QCborValue to the bootstrap library, it's
unlikely that we'll need this part. And by splitting it, I can make the
code handle more cases, that hadn't been properly handled before.

Thiago Macieira 340472534c QCborValue: refactor extended types so isTag() is true
This makes QCborValue more future compatible, as code written today for
tags that QCborValue does not recognize will continue to work if
QCborValue gains support for it in the future.

This change also obviates the need for reinterpretAsTag(), which I had
not written unit tests for as I knew this change was coming.

 2) should the both return the iterator to the next element too, like
    erase()?

This is very similar to QJsonDocument, but there's no QCborDocument.
QCborValue is that.

that permit DOM-like access to CBOR data. The API is similar to
QJsonValue, QJsonArray and QJsonObject, respectively.
