Rename "QEMU global mutex" to "BQL" in comments and docs

Browse source 
The term "QEMU global mutex" is identical to the more widely used Big
QEMU Lock ("BQL"). Update the code comments and documentation to use
"BQL" instead of "QEMU global mutex".

Coroutine safety can be hard to prove, similar to thread safety. Common
pitfalls are:
- The global mutex isn't held across ``qemu_coroutine_yield()``, so
- The BQL isn't held across ``qemu_coroutine_yield()``, so
operations that used to assume that they execute atomically may have
to be more careful to protect against changes in the global state.
