Add support for catching system calls to native FreeBSD targets.
All platforms on FreeBSD use a shared system call table, so use a single XML file to describe the system calls available on each FreeBSD platform. Recent versions of FreeBSD include the identifier of the current system call when reporting a system call entry or exit event in the ptrace_lwpinfo structure obtained via PT_LWPINFO in fbsd_wait. As such, FreeBSD native targets do not use the gdbarch method to fetch the system call code. In addition, FreeBSD register sets fetched via ptrace do not include an equivalent of 'orig_rax' (on amd64 for example), so the system call code cannot be extracted from the available registers during a system call exit. However, GDB assumes that system call catch points are not supported if the gdbarch method is not present. As a workaround, FreeBSD ABIs install a dummy gdbarch method that throws an internal_error if it is ever invoked. gdb/ChangeLog: * configure.ac: Check for support for system call LWP fields on FreeBSD. * config.in, configure: Rebuild. * data-directory/Makefile.in (SYSCALLS_FILES): Add freebsd.xml. * fbsd-nat.c (fbsd_wait) [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE]: Report system call events. [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE] (fbsd_set_syscall_catchpoint): New function. (fbsd_nat_add_target) [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE]: Set "to_set_syscall_catchpoint" to "fbsd_set_syscall_catchpoint". * fbsd-tdep.c: Include xml-syscall.h (fbsd_get_syscall_number): New function. (fbsd_init_abi): Set XML system call file name. Add "get_syscall_number" gdbarch method. * syscalls/freebsd.xml: New file.
