axfer: Declare global variables as 'extern' in header

Browse source 
This avoids multiple definitions of the same global variable (one in
each file that includes this header), and fixes a linking error when
compiled with -fno-common.

Fixes: 96110793b3 ("axfer: add support for a container of raw data")
