* Represents an immutable reference counted block of memory.
* This is basically the internal glib GBuffer structure exposed,
renamed, and with some additional capabilities.
* The GBytes name comes from python3's immutable 'bytes' type
* GBytes can be safely used as keys in hash tables, and have
functions for doing so: g_bytes_hash, g_bytes_equal
* GByteArray is a mutable form of GBytes, and vice versa. There
are functions for converting from one to the other efficiently:
g_bytes_unref_to_array() and g_byte_array_free_to_bytes()
* Adds g_byte_array_new_take() to support above functions

This is the ISO C sense of undefined behaviour, in which
works-by-coincidence, critical warning, abort, demons-fly-out-of-your-nose
are all valid implementations.

This was a regression in commit f41178c6c: flush_async_data wasn't
necessarily NULL in the "don't flush" case.
Also move initialization of these variables up so that it's
unconditional, since that's easier to verify than checking
that each branch gets it right.

If we can't get on the session bus, just behave like a normal non-unique
application.
This turns out to be remarkably easy to implement and lets us avoid
adding a 'dummy' backend.
Add a test for this case as well.
Idea from Zachary Dovel.

This happens to work at the moment (because GDBusWorker.frozen is a
gboolean and not just a 1-bit bitfield), but isn't right: the gboolean
ends up with values 0 or G_DBUS_CONNECTION_FLAGS_DELAY_MESSAGE_PROCESSING
(which is more than 1).

These might even make useful public API if they grew a Windows

We didn't previously flush in a couple of cases where we should have
done:
* a write is running when flush is called: we should flush after it
finishes
* writes have been made since the last flush, but none are pending or
running right now: we should flush the underlying transport straight
away

This makes it easier to schedule a flush, by putting it on the same code
path as writing and closing.
Also change message_written to expect the lock to be held, since all
that's left in that function either wants to hold the lock or doesn't
care, and it's silly to release the lock immediately before calling
message_written, which just takes it again.

When we use this function to schedule a flush, it'll be called
with the lock held. Releasing and immediately re-taking the lock would
be pointless.

maybe_write_next_message now also closes, and I'm about to make it
consider whether to flush as well, so its name is increasingly
inappropriate. Similarly, write_message_in_idle_cb is a wrapper around
it which could do any of those things.

If the user calls flush_sync() with no messages in the queue, but an
async write call pending, then we ought to flush after that async write
returns (although we don't currently do that). If it was an async close
or flush that was pending, there's no need to flush (again) afterwards.
So, we need to distinguish.

PKCS#8 is the "right" way to encode private keys. Although the APIs do
not currently support encrypted keys, we should at least support
unencrypted PKCS#8 keys.

The connect_async() calls would never terminated when an application side
proxy was being used. Note we also skip over TLS handshake in this case,
as the application may have to do some proxy handshake before.
