Add an option to use direct connections instead of via the bus. Clients
are accepted with QMP add_client.
This allows to provide the D-Bus display without a bus. It also
simplifies the testing setup (some CI have issues to setup a D-Bus bus
in a container).

Memory returned by get_relocated_path must be freed with
free or g_free depending on the path that the function
took; Coverity takes exception to this practice. The
fix lets caller use g_free as is standard in QEMU.
While at it, mention the requirements on the caller in
the doc comment.

"qemu/cutils.h" contains various qemu_strtosz_*() functions
useful to convert strings to size. It seems natural to have
the opposite usage (from size to string) there too.
The function definition is already in util/cutils.c.

qemu_strtosz() & friends reject NaNs, but happily accept infinities.
They shouldn't. Fix that.
The fix makes use of qemu_strtod_finite(). To avoid ugly casts,
change the @end parameter of qemu_strtosz() & friends from char **
to const char **.
Also, add two test cases, testing that "inf" and "NaN" are properly
rejected. While at it, also fixup the function documentation.

strchrnul is a GNU extension and thus unavailable on a number of targets.
In the review for a commit removing strchrnul from 9p, I was asked to
create a qemu_strchrnul helper to factor out this functionality.
Do so, and use it in a number of other places in the code base that inlined
the replacement pattern in a place where strchrnul could be used.
