Remove some lint, found by gcc -W etc.

* lib/rtapelib.c (do_command, rmt_write__): Use function
prototypes instead of old-style decls.
* paxlib/error.c (write_fatal): Remove unused and undeclared
function.
* paxlib/paxlib.h (stat_fatal, pax_exit): Add noreturn attribute.
(write_error_details): New decl.
* rmt/rmt.c (rmt_read, rmt_write, rmt_reply, rmt_error_message):
(rmt_error, xlat_kw, skip_ws, decode_open_flag, close_device):
(lseek_device, read_device, write_device, iocop_device, status_device):
Declare as static, since they're not exported.
Use function prototypes (void) instead of old-style decls ().
