docs: Drop glib-adoption.rst

It's been more than six months since we adopted GLib and we've
been pretty aggressive at replacing our homegrown APIs with more
standard ones, so by now most of the symbols mentioned in this
document haven't been around for quite a long time already.

-=====================
-Adoption of GLib APIs
-=====================
-
-Libvirt has adopted use of the `GLib
-library <https://developer.gnome.org/glib/stable/>`__. Due to
-libvirt's long history of development, there are many APIs in
-libvirt, for which GLib provides an alternative solution. The
-general rule to follow is that the standard GLib solution will be
-preferred over historical libvirt APIs. Existing code will be
-ported over to use GLib APIs over time, but new code should use
-the GLib APIs straight away where possible.
-
-The following is a list of libvirt APIs that should no longer be
-used in new code, and their suggested GLib replacements:
-
-``VIR_ALLOC``, ``VIR_REALLOC``, ``VIR_RESIZE_N``, ``VIR_EXPAND_N``, ``VIR_SHRINK_N``, ``VIR_FREE``, ``VIR_APPEND_ELEMENT``, ``VIR_INSERT_ELEMENT``, ``VIR_DELETE_ELEMENT``
-   Prefer the GLib APIs ``g_new0``/``g_renew``/ ``g_free`` in most
-   cases. There should rarely be a need to use
-   ``g_malloc``/``g_realloc``. Instead of using plain C arrays, it
-   is preferrable to use one of the GLib types, ``GArray``,
-   ``GPtrArray`` or ``GByteArray``. These all use a struct to
-   track the array memory and size together and efficiently
-   resize. **NEVER MIX** use of the classic libvirt memory
-   allocation APIs and GLib APIs within a single method. Keep the
-   style consistent, converting existing code to GLib style in a
-   separate, prior commit.
-``virStrerror``
-   The GLib ``g_strerror()`` function should be used instead,
-   which has a simpler calling convention as an added benefit.
-
-The following libvirt APIs have been deleted already:
-
-``VIR_AUTOPTR``, ``VIR_AUTOCLEAN``, ``VIR_AUTOFREE``
-   The GLib macros ``g_autoptr``, ``g_auto`` and ``g_autofree``
-   must be used instead in all new code. In existing code, the
-   GLib macros must never be mixed with libvirt macros within a
-   method, nor should they be mixed with ``VIR_FREE``. If
-   introducing GLib macros to an existing method, any use of
-   libvirt macros must be converted in an independent commit.
-``VIR_DEFINE_AUTOPTR_FUNC``, ``VIR_DEFINE_AUTOCLEAN_FUNC``
-   The GLib macros ``G_DEFINE_AUTOPTR_CLEANUP_FUNC`` and
-   ``G_DEFINE_AUTO_CLEANUP_CLEAR_FUNC`` must be used in all new
-   code. Existing code should be converted to the new macros where
-   relevant. It is permissible to use ``g_autoptr``, ``g_auto`` on
-   an object whose cleanup function is declared with the libvirt
-   macros and vice-versa.
-``VIR_AUTOUNREF``
-   The GLib macros ``g_autoptr`` and
-   ``G_DEFINE_AUTOPTR_CLEANUP_FUNC`` should be used to manage
-   autoclean of virObject classes. This matches usage with GObject
-   classes.
-``VIR_STRDUP``, ``VIR_STRNDUP``
-   Prefer the GLib APIs ``g_strdup`` and ``g_strndup``.
