Keeping it in error.py will create some cyclic import problems when we
add types to the QAPISchemaParser. Callers don't need to know the
details of QAPIParseError unless they are parsing or dealing directly
with the parser, so this won't create any harsh new requirements for
callers in the general case.

Built-in stuff is not parsed from a source file, and therefore have no
QAPISourceInfo. If such None info was used for reporting an error,
built-in stuff would be broken. Programming error. Instead of reporting
a confusing error with bogus source location then, we better crash.
We currently crash only if self.col was set. Assert that self.info is
not None in order to crash reliably.
We can not yet change the type of the initializer to prove this cannot
happen at static analysis time before the remainder of the code is fully

Rename QAPIError to QAPISourceError, and then create a new QAPIError
class that serves as the basis for all of our other custom exceptions,
without specifying any class properties.
This leaves QAPIError as a package-wide error class that's suitable for
any current or future errors.
(Right now, we don't have any errors that DON'T also want to specify a
Source location, but this MAY change. In these cases, a common abstract
ancestor would be desired.)

Per list review: qapi-code-gen.txt reserves suffixes Kind and
List only for type names, but the code rejects them for events and
commands, too.
It turns out we reject them earlier anyway: In check_name_upper() for
event names, and in check_name_lower() for command names.
Still, adjust the code for clarity over what precisely we are guarding

This is a small rewrite to address some minor style nits.
Don't compare against the empty list to check for the empty condition, and
move the normalization forward to unify the check on the now-normalized
structure.
With the check unified, the local nested function isn't needed anymore
and can be brought down into the normal flow of the function. With the
nesting level changed, shuffle the error strings around a bit to get
them to fit in 79 columns.
Note: although ifcond is typed as Sequence[str] elsewhere, we *know* that
the parser will produce real, bona-fide lists. It's okay to check
isinstance(ifcond, list) here.

Casts are instructions to the type checker only, they aren't "safe" and
should probably be avoided in general. In this case, when we perform
type checking on a nested structure, the type of each field does not
"stick".
(See PEP 647 for an example of "type narrowing" that does "stick".
It is available in Python 3.10, so we can't use it yet.)
We don't need to assert that something is a str if we've already checked
or asserted that it is -- use a cast instead for these cases.
