machine/stdarg.h -> sys/stdarg.h

Switch to using sys/stdarg.h for va_list type and va_* builtins.

Make an attempt to insert the include in a sensible place. Where
style(9) was followed this is easy, where it was ignored, aim for the
first block of sys/*.h headers and don't get too fussy or try to fix
other style bugs.

ddb: enable the use of ^C and ^S/^Q

This lets one interrupt DDB's output, which is useful if paging is
disabled and the output device is slow.

This follows a previous implementation in svn r311952

5fddef79998678d256ba30316353393b4d8ebb32 which was reverted because it
broke DDB type-ahead.

Now, try this again, but with a 512-byte type-ahead buffer. While there
is buffer space, control input is handled and non-control input is
buffered. When the buffer is exhausted, the default is to print a
warning and drop further non-control input in order to continue handling
control input. sysctl debug.ddb.prioritize_control_input can be set to
0 to instead preserve all input but lose immediate handling of control
input. This could for example effect pasting of a large script into the
ddb console.
