[PATCH] libosmocore[master]: Add abis_nm_fail_evt_vrep() function

[Max]

Hello Neels Hofmeyr, Jenkins Builder,

I'd like you to reexamine a change.  Please visit

    https://gerrit.osmocom.org/1569

to look at the new patch set (#2).

Add abis_nm_fail_evt_vrep() function

It accept fixed number of arguments including va_list instead of variable
number of arguments in abis_nm_fail_evt_rep() - similar to vprintff() vs
printf().
