* Decode a PLAYTUNE bytestream of notes as a time-ordered scroll, sort of like a
* piano roll with non-uniform time. This is a command-line program with no GUI.
*
*
* There are two primary uses:
*
* (1) To debug programming errors that cause some MIDI scripts to sound strange.
* (1) To debug errors that cause some MIDI scripts to sound strange.
*
* (2) To create a C-program array initialized with the bytestream, but annotated
* with the original notes. This is semantically the same as the normal output
* of MIDITONES, but is easier to edit manually. The downside is that the C
* source code file is much larger.
*
* In both cases it reads a .bin file that was created from a .mid file by MIDITONES
* using the -b option.
* In both cases it reads a xxx.bin file that was created from a MIDI file by
* MIDITONES using the -b option.
*
*
* For use case (1), just invoke the program with the base filename. The output is
* to the console, which can be directed to a file using the usual >file redirection.
* For example, starting with the original midi file "song.mid", say this:

* Starting with the original midi file "song.mid", say this:
* miditones -b song
* miditones_scroll song >song.txt
*
* and then the file "song.txt" will contain the piano roll.

* For example, starting with the original midi file "song.mid", say this:
*
* miditones -b song
* miditones_scroll -c song
*
* and then the file "song.c" will contain the PLAYTUNE bytestream C code.
*
*
* Other command-line options:
*
* -tn says that up to n tone generators should be displayed. The default
* is 6 and the maximum is 16.
*
* -v says that we expect the binary file to contain encoded note volume
* information as generated from Miditones with the -v option. That
* volume information is displayed next to each note.
*
* -vi says that we expect volume information to be in the file, but we
* should ignore it when creating the display.

/*
* Change log
*
* 26 February 2011, L.Shustek, V1.0
* -Initial release
* - Initial release
* 29 December 2013, L.Shustek, V1.1
* - Add a "-c" option to create C code output.
* Thanks go to mats.engstrom for the idea.
* xx yyyyyyyy zzzz, L.Shustek, V1.2
* - ???
* 04 April 2015, L. Shustek, V1.3
* -Made friendlier to other compilers: import source of strlcpy and strlcat,
* fixed various type mismatches that the LCC compiler didn't fret about.
* Generate "const" for data initialization for compatibility with Arduino IDE v1.6.x.
*
* - Made friendlier to other compilers: import source of strlcpy and strlcat,

* Generate "const" data initialization for compatibility with Arduino IDE v1.6.x.
* 5 August 2016, L. Shustek, V1.4
* - Add -v and -vi options to handle optional volume codes that Miditones can
* now generate.
* - Handle notes>127 as percussion, which Miditones can now generate
* - Make the number of generators be 16 maximum, but the number actually displayed
* can be specified by the -tn command-line option.
* - Remove string.h because OS X has macros for strlcpy; thus had to add strlen().
* (It's tough to write even non-GUI code for many environments!)
* - Add casts for where address subtraction is a long, like OS X.
