The C compiler will pick an enumeration type that accomodates the specified
values for the enumeration, so ignoring 64-bit enumerations, we can
have enumeration values from MININT32 to MAXUINT32. To handle this properly:
- Use gint64 for holding eumeration values when scanning
- Add a 'unsigned_value' bit to ValueBlob so we can distinguish the
int32 vs. uint32 cases in the typelib
- Change the return value of g_value_info_get_value() to gint64.

Previously we had both e.g. GI_TYPE_TAG_LONG and GI_TYPE_TAG_INT64,
but in fact the typelib is already machine-specific, so it makes sense
to just encode this as a fixed type. The .gir remains abstract.
We also remove size_t from the typelib; one would never want to treat
it differently than an integer.
time_t is removed as well; while bindings like gjs had special handling
to turn it into e.g. a JS Date object, I don't think we should encourage
people to use these POSIX types in their API. Use GTimeVal or the like
instead.
Because the typelib is now really machine-specific, we need to remove
the -expected.tgirs from git. (We could potentially add a check
which wasn't just a literal diff later)
