LineInfo uses perm_string for path.
...
Rework the handling of file names to use a perm_string heap to hold
the file names, instead of the custom file name heap in the lexor.
Also rename the get_line to get_fileline to reflect its real duties.
This latter chage touched a lot of files.

Check for extra digits in sized binary, octal and hex constants.
...
Print out a warning if extra digits are given for sized binary, octal
or hex constants. Decimal constants are very hard since we never
calculate the true number of bits the digits represent, so for now
decimal constants are not checked.

Decimal constants can be undefined or high-z.
