Pure code motion, except for two brace placements and a comment
tweaked to appease checkpatch.

-/**
- * qdict_crumple:
- * @src: the original flat dictionary (only scalar values) to crumple
- *
- * Takes a flat dictionary whose keys use '.' separator to indicate
- * nesting, and values are scalars, and crumples it into a nested
- * structure.
- *
- * To include a literal '.' in a key name, it must be escaped as '..'
- *
- * For example, an input of:
- *
- * { 'foo.0.bar': 'one', 'foo.0.wizz': '1',
- *   'foo.1.bar': 'two', 'foo.1.wizz': '2' }
- *
- * will result in an output of:
- *
- * {
- *   'foo': [
- *      { 'bar': 'one', 'wizz': '1' },
- *      { 'bar': 'two', 'wizz': '2' }
- *   ],
- * }
- *
- * The following scenarios in the input dict will result in an
- * error being returned:
- *
- *  - Any values in @src are non-scalar types
- *  - If keys in @src imply that a particular level is both a
- *    list and a dict. e.g., "foo.0.bar" and "foo.eek.bar".
- *  - If keys in @src imply that a particular level is a list,
- *    but the indices are non-contiguous. e.g. "foo.0.bar" and
- *    "foo.2.bar" without any "foo.1.bar" present.
- *  - If keys in @src represent list indexes, but are not in
- *    the "%zu" format. e.g. "foo.+0.bar"
- *
- * Returns: either a QDict or QList for the nested data structure, or NULL
- * on error
