pseudotalloc: Add simplistic implementation of talloc_asprintf
fsm.c uses this function. When compiled with --enable-embedded, it triggers a warning: fsm.c: In function 'osmo_fsm_inst_alloc': fsm.c:213:4: warning: implicit declaration of function 'talloc_asprintf' [-Wimplicit-function-declaration] fi->name = talloc_asprintf(fi, "%s(%s)", fsm->name, id); Change-Id: I61cd83d4c8570af1e452c945ac6f194baf7e6ac4
