Progress: Continue work on printing.

Progress: Continue work on printing.

Use ";" and ":" for ignore_index and ignore_range.
I intend to reserve "<", ">", "(", ")", "{", and "}" for context related matters, which currently is only color context.

The handling of UTF-8 character codes with ignore indexes and ranges needs to be carefully considered and documented.
Print safely functions will need to convert, but what if the bits are being ignored?
Print raw functions should print as-is, even if invalid.
Print normally functions should validate and return error.
For now I just added some comments.

Oops! I include space as a "control" character.

I started to convert byte_dump printing as a way of testing the current state of the code.
I intend to slowly convert each level 3 project one at a time and test for problems.
This quickly convinced me to not follow the fprintf() standards practice and I moved the FILE * after the string rather than before.

Finish the trim functions.
This is done very quickly so I am confident that there is some logic bug somewhere.
This is just another reason for me to implement testing support.

There are several utf_character trim functions in fl_print.
Remove these for now.
The print is getting big and I believe that I now need an fl_utf_print and an fll_utf_print just like is done with how fl_string has fl_utf_string.
I want to get all of the bugs out of the print functions before I move to working on the utf_print functions.
This will likely get addressed during a unicode development pass.

This converts some of the fll_program print functions.
Looking at the color print functions, I now plan on merging a lot of the color printing functionality into the print functions.
Specifically, the fl_print_string() and related should support color context printing.
This will allow me to simplify some of the code.
The idea so far is that I can use "[" and "]" to accept an "f_color_set_t" and the "[" represents the "before" pointer and the "]" represents the "after" pointer.

For example the following:
  fl_print_string(" %q%s%q%c", output.stream, *context.set.title.before, name, *context.set.title.after, f_string_eol_s[0]);
would be changed to:
  fl_print_string(" %[%s%]%c", output.stream, context.set.title, name, context.set.title, f_string_eol_s[0]);
