This patch does a number of things.
It adds file and line number information to the strobe_cb_info
structure. This allows the $swrite and $sformat calls to reference
their location in warning/error messages.
Their compiletf and calltf routines also display file and line
number information in messages.
The $display routine was converted to use the string formatting
routine. This can be reverted by defining USE_OLD_DISPLAY. The
old code will be removed once there has been more testing.
A number of bugs were fixed that were discovered with the
$display code.
The output of some conversions, variables and system functions
were changed to match the original display code or to better
match expectation.
Leading zero support was added to the %b/%b, %o/%O, %h/%H, %x/%X,
%c/%C and %d/%D. The floating point conversions already supported
adding a leading zero.
This is the start of converting all the various display tasks to use
the string formatting code and a cleanup/update of the sys_display.c
file in general.
