Version 1.49.92

- It's now possible to build GJS with sanitizers (ASan and UBSan) enabled; add
  "--enable-asan" and "--enable-ubsan" to your configure flags. This has
  already caught some memory leaks.

- There's also a "make check-valgrind" target which will run GJS's test suite
  under Valgrind to catch memory leaks and threading races.

- Many of the crashes in GNOME 3.24 were caused by GJS's closure invalidation
  code which had to change from the known-working state in 1.46 because of
  changes to SpiderMonkey's garbage collector. This code has been refactored to
  be less complicated, which will hopefully improve stability and debuggability.

- Closed bugs:

  * Clean up the idle closure invalidation mess [#786668, Philip Chimento]
  * Add ASan and UBSan to GJS [#783220, Claudio André]
  * Run analysis tools on GJS to prepare for release [#786995, Philip Chimento]
  * Fix testLegacyGObject importing the GTK overrides [#787113, Philip Chimento]
