If you called g_dbus_connection_remove_filter() on a filter while it
was running (or about to be run) in another thread, its GDestroyNotify
would be run immediately, potentially causing the filter thread to
crash.
Fix this by refcounting the filters, and using the existing mechanism
for running a GDestroyNotify in another thread in the case where the
the gdbus thread is the one that frees it.
Also, add a bit of documentation explaining this (and add a related
clarification to g_dbus_connection_signal_subscribe()).

• Remove copies of function declarations from the explanation — if
people want those, they can follow links to the reference manual.
• Add markup to make C code more defined.
• Remove use of first person and irrelevant name dropping.

So that first-time users don’t fall into the trap of reading about the
gory memory layout details of GType and GObject when all they wanted to
do was derive a class.

Use G_DECLARE_INTERFACE and G_DEFINE_INTERFACE. Fix a couple of typos.
Add some comments to empty functions to make it obvious they’re
intentionally empty.

Restructure the section of the how-to which covers the header and source
code boilerplate for declaring and defining GObjects to use the new
G_DECLARE_*_TYPE macros. Present both final and derivable types.
Trim various supporting paragraphs.
Rename ‘class functions’ to ‘virtual functions’ to use consistent,
modern terminology.

This will prevent attempting to read from some files that appear normal but are
really device-like, such as those in /proc and /sys.
If we can't stat() the file then don't bother attempting to sniff, either.

FreeBSD and NetBSD have field st_birthtim and st_birthtime in struct stat,
respectively, which can be used to get file creation time on supported file
systems such as UFS2 and tmpfs.

gvfs commit b358ca "Make sure metadata is always returned by
query_writable_namespaces()" changed the
query_writable_namespaces vfunc to never return NULL, but the error
checking in g_daemon_file_query_writable_namespaces still assumes vfunc
failure implies NULL return value and GError set. This causes a memory
leak as on failure the GError will be set but the vfunc implementation
will have created its own default list so NULL will not be returned, and
the GError will never be cleared.
This commit directly checks if the GError is set to detect failures,
my_error is directly dereferenced in the error block anyway.
This also removes an unneeded call to g_file_attribute_info_new(); as
the vfunc always returns us a non-NULL GFileAttributeInfoList.

These tests clear up a misunderstanding of mine: Monitoring
nonexisting files and directories *does* work with the inotify
implementation, it just has a very long timeout for scanning
for missing locations, so the test needs to take that into
account.
This is meant for opaque, non-POSIX-like backends to indicate that the
URI is not persistent. Applications should look at
G_FILE_ATTRIBUTE_STANDARD_SYMLINK_TARGET for the persistent URI.
Examples of such backends could be a portal for letting sandboxed
applications access the file-system, or a database-backed storage like
Google Drive.
In these cases, the user visible file and folder names are different
from the real identifiers, used by the backend. So, a request to
create google-drive://user@gmail.com/foo/New\ File, would actually
lead to google-drive://user@gmail.com/foo/bar on the server even though
the user visible name is still "New File". Since the server-defined URI
is persistent and sanity-checked by the backend, it is recommended that
applications switch to it as soon as possible. Backends will try to
keep a mapping from "fake" to "real" URIs, but those are only on a
best effort basis. They might not be persistent or have the same
guarantees as the "real" URIs.

g_dbus_method_invocation_return_value(), etc, don't have GError
parameters (which makes sense since they won't usually return errors,
and there's not much you could do if they did), so in the rare case
when something does go wrong, they print a warning.
However, there is at least one situation where the warning is a bad
idea: if you are using private bus connections, and a client connects,
makes a request, and then disconnects before getting the response.
Given that there's nothing the caller can do to prevent this case from
getting hit (since the client might not disconnect until after the
call to g_dbus_method_invocation_return_value() starts) and given that
the server can never actually know for sure that the client has
received the response (it might disconnect after reading the response,
but before processing it), just kill the warning in this case.
