Use non-burst event enqueue and dequeue calls from burst enqueue and
dequeue only when the burst size is compile-time constant (and equal
to one).
Signed-off-by: Mattias Rönnblom <mattias.ronnb...@ericsson.com>

v3: Actually include the change v2 claimed to contain.
v2: Wrap builtin call in __extension__, to avoid compiler warnings if
application is compiled with -pedantic. (Morten Brørup)
