Exported input global data and empty_side() function
Declared non-exported functions static
Moved horiz_precalc(), vert_precalc(), horiz_assemble(), vert_assemble(),
horiz_generate(), vert_generate(), generate_box() and output_box() to a
new file generate.c
Moved best_match(), hmm(), detect_horiz(), detect_design(), remove_box()
and output_input() to a new file remove.c
Moved iscorner(), on_side(), isempty(), shapecmp(), both_on_side(),
shape_distance(), empty_side(), highest(), and widest() as well as
some data structures and macros related to shapes to new file shape.c
Moved MAX_TABSTOP, LINE_MAX macros to boxes.h
Moved BMAX, strrstr, btrim(), yyerror(), expand_tabs_into(), regerror(),
empty_line() to a new file tools.c, added #include tools.h
Some cleanup in main()
Declared style_sort() helper function static
Renamed strrstr() to my_strnrstr() (now defined in tools.c)
Default design is now defined by DEF_DESIGN macro
Moved struct opt_t to boxes.h
Bugfix: segfaulted if shape was bigger than input when detecting design
Bugfix: Padding was not removed when box was removed
Bugfix: Forgot null byte when removing west box side
Changed select_design(), because default design value now set in process_commandline()
Added opt_t and opt global variable from boxes.c
Moved BFREE macro and yyerror() and empty_line() prototypes to tools.h
Added LINE_MAX and MAX_TABSTOP macros from boxes.c
Added #define DEBUG and REGEXP_DEBUG. This will centrally activate

Unified use of current_re[pv]rule
Added a few comments and debugging code
Regular expression substituions on input text only if *drawing* a box,
not if the box is to be removed (requires other substitutions, TODO).
