Subject: Fix clang linking problem

Inlining was not done in a portable way. clang follows the C99
semantics for inlining ('inline' essentially implies 'static' in
C99, but not in GCC), so bp_sched2ix() was not visible outside
beam_bp.c. Since the function need to be used from more than one
source file, put the function definition in the beam_bp.h header
file. Also, give it an 'erts_' prefix since it is globally visible.
