gio: add a missing property to GDummyTlsConnection

GDummyTlsConnection didn't implement the "interaction" property,
meaning you'd get warnings if you tried to set it while creating a
GTlsConnection when using the dummy backend. (Of course, trying to
create the GTlsConnection will fail anyway, but it ought to fail
without hitting any g_warnings.)

docs: Add a README.rationale documenting major design decisions

It will be useful to document the major decisions which affect the whole
of GLib in one centralised, easily-greppable file, otherwise they will
get lost forever in Bugzilla.

This file should contain a brief explanation of the decision and its
rationale, plus a link to further discussion (e.g. on a mailing list or
bug report).

This contains an initial discussion about use of compiler attributes in
GLib.

gio: iostream: use GTask instead of internal pointer

This fixes an infinite recursion loop when calling
g_io_stream_close_async() on a SoupIOStream.

goption: Don't include parsed option values in G_OPTION_REMAINING

After a call to g_option_context_set_ignore_unknown_options(context, TRUE),
the values of short options were included in the array returned by a
G_OPTION_REMAINING option.

https://bugzilla.gnome.org/show_bug.cgi?id=729563
Add a testcase for the previous fix

This testcase tests that short option arguments are
not erroneously added to the remaining argument array
when g_option_context_set_ignore_unknown_options is
called.

AppInfo: use XDG_CURRENT_DESKTOP for OnlyShowIn

Expand the functionality of g_desktop_app_info_set_desktop_env() to
include the possibility of passing strings containing ':' characters (as
some apps, such as gnome-session, are directly passing the value of
XDG_CURRENT_DESKTOP).  At the same time, deprecate it, since now we get
the list from the environment variable for ourselves.

Modify the checks in g_desktop_app_info_get_show_in() to deal with
multiple items listed in XDG_CURRENT_DESKTOP.  For example, if we find
that we have

  XDG_CURRENT_DESKTOP=GNOME-Classic:GNOME

and a desktop file contains:

  OnlyShowIn=GNOME

then we will show this file because of the fallback to GNOME.  If the
file _also_ contains the line:

  NotShowIn=GNOME-Classic

Then we will not show it, because GNOME-Classic comes before GNOME in
XDG_CURRENT_DESKTOP.

gio: cleanup gdbusmessage.c file

* removed passing GError to ensure_input_padding() function
  - it was necessary before commit 3e5214c15c2a19b64d74e714
  when we used GData*Streams and GMemoryInputStream with
  g_seekable_seek() - now it's useless,

* removed checking return value of ensure_input_padding()
  function - in previous implementation (like above)
  g_seekable_seek() could return FALSE - now it's always TRUE,

* removed passing GError to g_memory_buffer_read_*() functions
  and checking returned value - it also has been inherited after
  old implementation with g_data_input_stream_read_*() functions
  - now it's also useless

* cleaned up code formatting,

gio/gtestdbus.c: Fix write_config_file() for Windows

Windows does not like g_unlink() to be called on files whose file
descriptor is still open, so doing that would cause a permission
denied error.  Since the fd is not used in that function after
acquiring the temp file, close it earlier before
g_file_set_contents(), so that it can complete successfully.

This fixes a number of GTK+ tests on Windows.

Remove some markup from docs
Avoid overeager warning about deprecated properties

Construct properties are always set during construction.
It makes no sense to warn about this even if the property
is marked as deprecated; the deprecation warning should
only be issues for explicit uses of the property after
construction.
