qapi: Fix error handling code on alternate conflict
The conflict check added by commit c0644771 ("qapi: Reject
alternates that can't work with keyval_parse()") doesn't work
with the following declaration:
{ 'alternate': 'Alt',
'data': { 'one': 'bool',
'two': 'str' } }
It crashes with:
Traceback (most recent call last):
File "./scripts/qapi-types.py", line 295, in <module>
schema = QAPISchema(input_file)
File "/home/ehabkost/rh/proj/virt/qemu/scripts/qapi.py", line 1468, in __init__
self.exprs = check_exprs(parser.exprs)
File "/home/ehabkost/rh/proj/virt/qemu/scripts/qapi.py", line 958, in check_exprs
check_alternate(expr, info)
File "/home/ehabkost/rh/proj/virt/qemu/scripts/qapi.py", line 830, in check_alternate
% (name, key, types_seen[qtype]))
KeyError: 'QTYPE_QSTRING'
This happens because the previously-seen conflicting member
('one') can't be found at types_seen[qtype], but at
types_seen['QTYPE_BOOL'].
Fix the bug by moving the error check to the same loop that adds
new items to types_seen, raising an exception if types_seen[qt]
is already set.
Add two additional test cases that can detect the bug.
