Change log for id3, the ID3 tag editor

1.0.0
-----

- Development taken over by Peter Pentchev.

  avoid backquotes in the usage string.
- Import a Debian patch by Stefan Ott <stefan@ott.net> and
  Peter Pentchev to let the compiler and linker flags be
  overridden.
- Let the install program and the strip flag also be overridden.
- Check some more functions' return values for errors.
- Add some preprocessor and compiler flags to specify certain
  POSIX and C environment standards.
- Reorder the #include statements.
- Also include <strings.h> for strncasecmp().
- Mark the list of genres in genre.h as "const char".
- Add a lot of GCC-specific compiler warning flags.
- Use the err(3) and warn(3) functions, they're portable enough.
- Mark several global variables as static.
- Break the display of the ID3 tags out into a separate function.
- Use "return" from main(), remove unreachable "break" statements.
- Avoid possible out-of-bound copying when storing command-line
  arguments into the new tag structure.
- Expect a C99 compiler and reduce the scope of some variables.
- Use the C99 "bool" type for, well, boolean flags.
- Convert the id3.1 manual page to the mdoc format.
- Fix the fields length in the manual page - only the comment is
  limited to 28 characters, the rest of the text fields are at 30.
- Use the more common "file..." instead of "file1 [file2 [file3...]]"
- Fill in some commonly-used manual page sections.
- Validate number-to-string conversions for the genre and track number.
- Fix a signedness error in the track number display.
