There are several reasons why we might not be able to do the test setup
for --external-data: non-Linux platform, missing ld or objcopy,
objcopy doesn't support --add-symbol, or the CPU family is MIPS
(on which cc -r does not necessarily emit the specific MIPS ABI flavour
that we are targeting, for example different functionality levels or
different NaN encodings).
If we can't link in the test data, then obviously this test is not going
to pass. It was already skipped on non-Linux, but not on platforms that
hit one of the other reasons for the test setup to fail.
In particular, this test failed on Debian mips64el since commit 81059169,
which stopped linking the necessary resource on MIPS platforms, but
continued to assert that the resource is present at runtime.

The title of an interface can be arbitrarily long, considering that
reverse DNS namespaces can be pretty complex. Instead of using the whole
interface name, we can use the name without the prefix.
Generating gir and typelib files has inter-dependencies that may depend
on other elements.
For example, glib requires gobject and gdump generated files require
gmodule, so we've a cyclic dependency because gmodule requires gobject,
that requires glib.
To prevent this, let's just generate the introspection files at once in
a different meson file so that we don't have to deal with this.
As per this we could even revert commit fa37ab6d0 since gio is now
compiled before the gir files.
The code for stripping the query and fragment from file:// URIs was
wrong, as it would not properly strip a query if there was a fragment.
Fortunately, that code was actually useless, as the "stripped URI" was
passed to g_filename_from_uri() that does proper stripping itself.
So simply drop this extra unnecessary stripping logic from GLocalVFS's
get_file_for_uri() and let g_filename_from_uri() do all the work.
The same struct was reused across multiple tests, but without a shared
way of freeing its members. Refactor to add one.

The current buffer API is pretty much C-specific, and cannot be
adequately described in a way that is friendly to introspection and
language bindings: the passed buffer is allocated by the caller, but the
written size of the buffer is in the return value.
Using GBytes, we get a better API at the cost of an additional
allocation.
This is just the result of running `black $(git ls-files '*.py')`.
For some reason, the `sh-and-py-check` CI job didn’t run on merge
request !3751, so this non-standard formatting slipped through onto
`main`.

It can cause failures for shared connection objects.
What can currently happen is this:
1. A user starts to asynchronously create a proxy object
2. A user starts to asynchronously create another proxy object
At this point, the asynchronous initialization for the two proxy objects
share the not yet initialized connection object.
3. While the shared connection objected is created, the user cancels the
creation with the supplied cancellable from the fist proxy object.
4. initable_init caches the canceled error and marks the connection as
initialized.
5. The initialization of the second proxy object fails with the same
canceled error.
To avoid this, clear the error in this case and destroy any member
variables that may have been created before the creation was canceled.
This way, the initialization of the second proxy object will restart the
connection initialization and with probably succeed.

Previously, the code only validated the types of *required* message
headers, and did not validate optional ones.
Now, the headers are validated in one step, and a subsequent step checks
whether the required ones are present.
The existing tests have been updated to match the new error message
wording. More tests will be added to test the new behaviour in a
subsequent commit.

Before checking the properties of `*_proxy`, assert that there were no
errors in constructing the proxy first. Otherwise the property checks
will crash on `NULL` pointer dereferences.
The test is still intermittently buggy somewhere, but at least this
commit will cause a relevant error message to be printed on failure.

Just for debugging purposes, track whether the Connection Attempt Delay
(https://datatracker.ietf.org/doc/html/rfc8305#section-8) has been
reached for each attempt.
This makes it a bit easier to diagnose `GSocketClient` problems in a
debugger.

This makes it match the terminology from RFC 8305 better, which refers
to a ‘connection attempt delay’. This is a delay because it determines
the spacing between trying additional connection attempts. It’s not a
timeout because it shouldn’t cause cancellation of any ongoing
connection attempts.
This commit introduces no functional changes.

`TCP_NODELAY` disables Nagle’s algorithm, which is generally a better
default for modern networks than having it enabled. Nagle’s algorithm
delays sending small data blobs until they fill an entire TCP segment,
so as to amortise the cost of sending the segment.
This improves bandwidth at the cost of latency. Given the large
bandwidth capabilities of most modern networks, most streams are
constrained by latency rather than bandwidth, so disabling Nagle’s
algorithm makes sense.
Various other major bits of software (such as libcurl) already disable
Nagle’s algorithm by default.
Specific applications which need it can turn it back on by calling
`g_socket_set_option()`.

Fixes: #791
As spotted by Michael Catanzaro in
https://gitlab.gnome.org/GNOME/glib/-/merge_requests/3394#note_1730123,
on the code path where a `ConnectionAttempt` is cancelled, it will
currently be removed from the `connection_attempts` list by the
cancellation code, and then *again* by the `if
(task_completed_or_cancelled ())` code in
`g_socket_client_connected_callback()`.
That would previously have resulted in a double-unref of the
`ConnectionAttempt`. So change `connection_attempt_remove()` to be a
no-op if the attempt isn’t found in `connection_attempts`.

These calls are where the `GSocketClient` Happy Eyeballs code relies on
other components within GLib (and glib-networking) to complete
asynchronous operations in a timely manner. `GSocketClient` doesn’t add
its own timeouts to monitor these async operations, so if the
implementations are buggy then a `GSocketClient` operation could stall
forever.
Make that a bit clearer.

`P_()` is for pspec strings — it gave us the option to split them out to
a separate translation domain. `_()` is for normal strings.
