qapi: qapi-visit.py, fix list handling for union types

Currently we assume non-list types when generating visitor routines for
union types. This is broken, since values like ['Type'] need to mapped
to 'TypeList'.

We already have a type_name() function to handle this that we use for
generating struct visitors, so use that here as well.

json-parser: fix handling of large whole number values

Currently our JSON parser assumes that numbers lacking a fractional
value are integers and attempts to store them as QInt/int64 values. This
breaks in the case where the number overflows/underflows int64 values (which
is still valid JSON)

Fix this by detecting such cases and using a QFloat to store the value
instead.

qapi: add QMP input test for large integers

Large integers previously got capped to LLONG_MAX/LLONG_MIN so we could
store them as int64_t. This could lead to silent errors occuring.

Now, we use a double to handle these cases.

Add a test to confirm that QMPInputVisitor handles this as expected if
we're expected an integer value: errors for out of range integer values
that got promoted to doubles in this fashion.

qapi: fix visitor serialization tests for numbers/doubles

We never actually stored the stringified double values into the strings
before we did the comparisons. This left number/double values completely
uncovered in test-visitor-serialization tests.

Fixing this exposed a bug in our handling of large whole number values
in QEMU's JSON parser which is now fixed.

Simplify the code while we're at it by dropping the
calc_float_string_storage() craziness in favor of GStrings.
