• global.c (gcry_control): Call global_init() after passing thread

cbs to ath. global_init() MUST to be called AFTER passing the cbs
to ath and BEFORE calling library functions, which make use of
ath. This change combines cbs installing with ath initialization
and thus removes the need to call other library initialization
functions inbetween like e.g. gcry_check_version().
