* cp-abi.c: Include "command.h", "gdbcmd.h", and "ui-out.h".
(auto_cp_abi): New variable. (current_cp_abi, num_cp_abis): Make static. (CP_ABI_MAX): Define. (cp_abis): Turn into an array. (value_virtual_fn_field): Fix formatting. (switch_to_cp_abi, register_cp_abi): Update. register_cp_abi now takes a pointer. (set_cp_abi_as_auto_default, set_cp_abi_cmd, show_cp_abi_cmd) (list_cp_abis, _initialize_cp_abi): New functions. * cp-abi.h: Add prototype for set_cp_abi_as_auto_default. Remove declarations for cp_abis, num_cp_abis, current_cp_abi, and switch_to_cp_abi. Update prototype for register_cp_abi. * Makefile.in (cp-abi.o): Update dependencies. * minsyms.c (install_minimal_symbols): Call set_cp_abi_as_auto_default instead of switch_to_cp_abi. * gnu-v2-abi.c (_initialize_gnu_v2_abi): Likewise. Update call to register_cp_abi. * gnu-v3-abi.c (_initialize_gnu_v3_abi): Update call to register_cp_abi. * hpacc-abi.c (_initialize_hpacc_abi): Likewise.
