Fix several warnings for -Wmissing-prototypes

* device/ds_routines.c: use static qualifier.
* device/subrs.c: delete unused functions.
* i386/i386/ast_check.c: include prototypes in kern/ast.h
* i386/i386/db_disasm.c: Include prototypes in ddb/db_examine.h
* i386/i386/db_interface.h: Define prototype for kdb_kentry. Expose
  debug methods feep and kd_debug_put.
* i386/i386/db_trace.c: delete left over cthreads support, functions are
  not used.
* i386/i386/model_dep.h: Define prototype for c_boot_entry.
* i386/i386at/acpi_parse_apic.c: Static qualifiers.
* i386/i386at/autoconf.c: Include header file for prototypes and remove
  dead code.
* i386/i386at/autoconf.h: Fix prototype.
* i386/i386at/com.c: Add static qualifiers, delete dead code.
* i386/i386at/com.c: ditto.
* i386/i386at/com.h: Define prototypes for debug functions.
* i386/i386at/int_init.c: Include header.
* i386/i386at/kd.c: Include header for debug interface. Remove dead
  kd_cmdreg_read and make xga_getpos static.
* i386/i386at/kd_mouse.c: Static qualifiers.
* i386/i386at/lpr.c: Dead lprpr.
* i386/i386at/model_dep.c: Remove exit function.
* kern/mach_clock.c: Include mig prototypes.
* kern/mach_clock.h: Remove duplicates of mig prototypes.
* kern/machine.c: Use static.
* kern/startup.c: slave_main is unused.
* kern/thread.h: Define thread_stats that is useful for debugging.
* kern/timer.c: Keep db_thread_times since it can be used for debugging.
* kern/timer.h: ditto.
* linux/dev/glue/misc.c: Use mig header for host_get_time.
