The GDBusConnectionFlags and GDBusServerFlags can affect how we carry
out authentication and authorization, either making it more or less
restrictive, so it's desirable to "fail closed" if a program is compiled
against a new version of GLib but run against an old version.

The intention here was to assert that the length of the password fits
in a gssize. Passwords more than half the size of virtual memory are
probably excessive.

The public API `g_tls_password_set_value_full()` (and the vfunc it
invokes) can only accept a `gssize` length. Ensure that nul-terminated
strings passed to `g_tls_password_set_value()` can’t exceed that length.
Use `g_memdup2()` to avoid an overflow if they’re longer than
`G_MAXUINT` similarly.

Don’t use an `int`, that’s potentially too small. In practical terms,
this is not a problem, since no socket address is going to be that big.
By making these changes we can use `g_memdup2()` without warnings,
though. Fewer warnings is good.

Previously, the code in `convert_path()` could not handle keys longer
than `G_MAXINT`, and would overflow if that was exceeded.
Convert the code to use `gsize` and `g_memdup2()` throughout, and
change from identifying the position of the final slash in the string
using a signed offset `i`, to using a pointer to the character (and
`strrchr()`). This allows the slash to be at any position in a
`G_MAXSIZE`-long string, without sacrificing a bit of the offset for
indicating whether a slash was found.

This allows it to handle strings up to length `G_MAXSIZE` — previously
it would overflow with such strings.
Update the several copies of it identically.

Previously it was handled as a `gssize`, which meant that if the
`stop_chars` string was longer than `G_MAXSSIZE` there would be an
overflow.

The members of `URL_COMPONENTS` (`winhttp_file->url`) are `DWORD`s, i.e.
32-bit unsigned integers. Adding to and multiplying them may cause them
to overflow the unsigned integer bounds, even if the result is passed to
`g_memdup2()` which accepts a `gsize`.
Cast the `URL_COMPONENTS` members to `gsize` first to ensure that the
arithmetic is done in terms of `gsize`s rather than unsigned integers.

Convert all the call sites which use `g_memdup()`’s length argument
trivially (for example, by passing a `sizeof()`), so that they use
`g_memdup2()` instead.
In almost all of these cases the use of `g_memdup()` would not have
caused problems, but it will soon be deprecated, so best port away from
it.

We're using "setuid" here as shorthand for any elevated privileges
that should make us distrust the caller: setuid, setgid, filesystem
capabilities, more obscure Linux things that set the AT_SECURE flag
(such as certain AppArmor transitions), and their equivalents on
other operating systems. This is fine if we do it consistently, but
I'm about to add a check for whether we are *literally* setuid,
which would be particularly confusing without a rename.

Various tests have leaks where it isn't clear whether the data is
intentionally not freed, or leaked due to a bug. If we mark these
tests as TODO, we can skip them under AddressSanitizer and get the
rest to pass, giving us a baseline from which to avoid regressions.

AddressSanitizer, UndefinedBehaviourSanitizer and probably others
involve adding instrumentation into the code under test, which doesn't
go well with LD_PRELOAD modules that absolutely need to be
self-contained.
