tipc: Relocate trivial link status functions to header file
Rather than live in link.c where they can only be used in that file alone, these helper routines are better served by being in link.h Relocated are the following: link_working_working link_working_unknown link_reset_unknown link_reset_reset link_blocked link_congested Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: David S.
