symbol__disassemble_capstone in util/disasm.c calls function open_capstone_handle to open/init the capstone. We already have a capstone_init function in "util/print_insn.c". But capstone_init is defined as a static function in util/print_insn.c. Change this and also add the function in print_insn.h The open_capstone_handle checks the disassembler_style option from annotation_options to decide whether to set CS_OPT_SYNTAX_ATT. Add that logic in capstone_init also and by default set it to true.
