Incompatible changes

• The header file, library file and other files are renamed from oniguruma* or onig* to onigmo*. This aims to avoid conflict with Oniguruma 6.x. (Issue #66)

  • Ruby specific parts are now sorrounded by #ifdef RUBY .. #endif.
  • Ruby specific onig_compile() is now named onig_compile_ruby().
  • Some APIs have end parameter now. E.g. onigenc_get_prev_char_head().
  • Some encoding names were changed. E.g.: "CP932" -> "Windows-31J".
  • Encoding structs and syntax structs are now constants.
• The behavior of [[:punct:]] on Unicode encodings is changed. Now [[:punct:]] matches the nine characters $+<=>^|~` on all encodings. (Issue #42)
• Drop support for very old compilers. For MSVC, VC2005 or later is required. For other platforms, ANSI C89 is required. (Issue #72)
• Remove ONIG_OPTION_POSIX_REGION. (Issue #75)
• Value of some constants were changed. E.g. ONIG_OPTION_NOTBOS
