Log Message:
Update glib2 to 2.66.0

Highlights:
* Fixes to the new `statx()` calls - note that since GLib 2.65.2 uses `statx()`
  (if available) instead of `stat()`/`fstat()`/`lstat()`/`fstatat()`, syscall
  sandboxing for third party applications might need to be updated
* Fix deadlock in `g_subprocess_communicate_async()` (work by Alexander Larsson) \ 
(#2182)
* Add `%f`/microsecond placeholder support to `g_date_time_format()` (work by \ 
Johan Bjäreholt) (!1605)
* Add `GUri` API for parsing, building and representing URIs according to
  [RFC 3986](https://tools.ietf.org/html/rfc3986) (work by Marc-Andre Lureau) (#110)
* D-Bus credentials support on macOS (#507)
* Year 2038 fixes involving new API in `GBookmarkFile` (#1931)
