Regression from 501ff95c. Union member offsets are always 0, but we need
to mark them as 'COMPUTED' otherwise they are not written to the
typelib, which results in gi_field_info_get_offset() returning 0xffff.
Since gi_field_info_get/set_field() cannot check that the offset is
within the size of the struct or union, that means poking into invalid
memory addresses.
This also adds some basic tests for GIFieldInfo which would have caught
this bug.
Closes: #3745
`GIIrNodeField` 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.
This also includes some offset validity changes which were forgotten
from commit 515b3fc1dc.

Do this by tracking the state of the size/alignment calculations
separately, rather than bunging it into the `alignment` field using
magic values.

Note that for alignments we should actually use size_t, but this would
imply some refactors since this value can be acually set to -1 in our
implementation.
So we use gssize for now, that at least on gcc is defined.
Review and update the documentation, making sure it’s complete,
formatted in gi-docgen format, and has all appropriate GIR annotations
and `Since:` lines.

Now that libgirepository uses `GI_AVAILABLE_IN_*` macros, that’s what
controls symbol visibility. The `_` prefixes are redundant, and out of
keeping with the rest of GLib.

Rather than a mix of structs being in `GI` and their methods being in
`g_`.
We’ve chosen not to use the `g_` namespace because a number of the
libgirepository class names are quite generic, so we’d end up with
confusing symbols like `GScopeType` and `GArgument`.

Add the SPDX license runes to all the files which have an obvious
copyright header already. This is a mechanical edit.
