[gjs] Created tag 1.57.3

[Philip Chimento <pchimento src gnome org>]

The unsigned tag '1.57.3' was created.

Tagger: Philip Chimento <philip chimento gmail com>
Date: 1561055585 -0700

    Version 1.57.3
    
    - The GJS profiler is now integrated directly into Sysprof 3, via the
      GJS_TRACE_FD environment variable. Call stack information and garbage
      collector timing will show up in Sysprof. See also GNOME/Initiatives#10
    
    - New JS API: System.addressOfGObject(obj) will return a string with the hex
      address of the underlying GObject of `obj` if it is a GObject wrapper, or
      throw an exception if it is not. This is intended for debugging.
    
    - New JS API: It's now possible to pass a value from Gio.DBusProxyFlags to the
      constructor of a class created by Gio.DBusProxy.makeProxyWrapper().
    
    - Backwards-incompatible change: Trying to read a write-only property on a DBus
      proxy object, or write a read-only property, will now throw an exception.
      Previously it would fail silently. It seems unlikely any code is relying on
      the old behaviour, and if so then it was probably masking a bug.
    
    - Closed bugs and merge requests:
      * Build failure on Continuous [#253, !300, Philip Chimento]
      * build: Bump glib requirement [!302, Florian Müllner]
      * profiler: avoid clearing 512 bytes of stack [!304, Christian Hergert]
      * system: add addressOfGObject method [!296, Marco Trevisan]
      * Add support for GJS_TRACE_FD [!295, Christian Hergert]
      * Gio: Make possible to pass DBusProxyFlags to proxy wrapper [!297, Marco
        Trevisan]
      * Various maintenance [!301, Philip Chimento]
      * Marshalling of GPtrArray broken [#9, !307, Stéphane Seng]
      * Build fix [!308, Philip Chimento]
      * Gio: sync dbus wrapper properties flags [!298, Marco Trevisan]
