[PATCH 0/1] MR9019: libs/fluidsynth: Fix memory leak / use-after-free crash due to incorrect refcounting

[Jinoh Kang (＠iamahuman)]

FluidSynth settings table is internally a refcounted hashtable.

Due to wrong glib atomic emulation, the hashtable might be leaked (if refcount != 2) or abruptly freed (if refcount == 2) due to incorrect return value from `fluid_atomic_int_exchange_and_add()`.
