Philip Withnall 0909b2e3ac girnode: Improve int types in GIIrNodeUnion 
`GIIrNodeUnion` is built dynamically at runtime (rather than being
mmapped from disk), so its types can accurately reflect their runtime
semantics, rather than an on-disk format.

As part of this, switch from `atoi()` to `g_ascii_string_to_unsigned()`
for parsing the relevant fields from a GIR XML file. This means we now
get error handling for invalid integers.
