Markus Armbruster d2f95f4d48 qapi: Use QNull for a more regular visit_type_null()
Make visit_type_null() take an @obj argument like its buddies.  This
helps keep the next commit simple.

Marc-André Lureau 5923f85fb8 qapi: update the qobject visitor to use QNUM_U64
Switch to use QNum/uint where appropriate to remove i64 limitation.

The input visitor will cast i64 input to u64 for compatibility
reasons (existing json QMP client already use negative i64 for large
u64, and expect an implicit cast in qemu).

Note: before the patch, uint64_t values above INT64_MAX are sent over
json QMP as negative values, e.g. UINT64_MAX is sent as -1. After the
patch, they are sent unmodified.  Clearly a bug fix, but we have to
consider compatibility issues anyway.  libvirt should cope fine,
because its parsing of unsigned integers accepts negative values
modulo 2^64.  There's hope that other clients will, too.

Marc-André Lureau 01b2ffcedd qapi: merge QInt and QFloat in QNum
We would like to use a same QObject type to represent numbers, whether
they are int, uint, or floats. Getters will allow some compatibility
between the various types if the number fits other representations.

Add a few more tests while at it.

Daniel P. Berrange 7d5e199ade qapi: rename QmpOutputVisitor to QObjectOutputVisitor
The QmpOutputVisitor has no direct dependency on QMP. It is
valid to use it anywhere that one wants a QObject. Rename it
to better reflect its functionality as a generic QAPI
to QObject converter.

The commit before previous renamed the files, this one renames C
identifiers.

Daniel P. Berrange b3db211f3c qapi: rename *qmp-*-visitor* to *qobject-*-visitor*
The QMP visitors have no direct dependency on QMP. It is
valid to use them anywhere that one has a QObject. Rename them
to better reflect their functionality as a generic QObject
to QAPI converter.

This is the first of three parts: rename the files.  The next two
parts will rename C identifiers.  The split is necessary to make git
rename detection work.
