osabi sniffer, signal handling initializer, 'in_dynsym_resolve_code' function and nto_set_target function. (struct nto_target_ops): Put comments inline with struct. Add osabi sniffer hook. Redefine macros to permit testing/assignment. Remove nto_ prefix from members. * nto-tdep.c (nto_find_and_open_solib): Allocate all buffers dynamically to support arbitrary root paths. Check for basename of lib in search path and then check for absolute. (nto_in_dynsym_resolve_code): New function. (nto_core_sniffer): New function. (regset_core_fns): Register core sniffer. (nto_initialize_signals): New function. (_initialize_nto_tdep): Move signal initialization code to above to avoid initialization race conditions. (nto_set_target): New function. * nto-procfs.c: Minor formatting/indenting changes. (procfs_is_nto_target): New function. (procfs_open): Set nto_is_nto_target. (_initialize_procfs): Ditto. Remove notice_signals() call to avoid initialization race conditions. (procfs_create_inferior): Resume inferior after creation. * i386-nto-tdep.c: Declare i386_nto_target. (init_i386nto_ops): Initialize i386_nto_target instead of current_nto_target. (i386nto_init_abi): Initialize signals. Call nto_set_target. Set TARGET_SO_IN_DYNSYM_RESOLVE_CODE.
