       Support for m17n library users to debug their programs.

       The m17n library provides the following facilities to support the library users to debug their programs.

       • Environment variables to control printing of various information to stderr.
         • MDEBUG_INIT  --  If  set  to  1,  print  information  about the library initialization on the call of
           M17N_INIT().
         • MDEBUG_FINI -- If set to 1, print  counts  of  objects  that  are  not  yet  freed  on  the  call  of
           M17N_FINI().
         • MDEBUG_CHARSET -- If set to 1, print information about charsets being loaded from the m17n database.
         • MDEBUG_CODING  --  If  set  to  1,  print information about coding systems being loaded from the m17n
           database.
         • MDEBUG_DATABASE -- If set to 1, print information about data being loaded from the m17n database.
         • MDEBUG_FONT -- If set to 1, print information about fonts being selected and opened.
         • MDEBUG_FLT -- If set to 1, 2, or 3, print information about which command of Font  Layout  Table  are
           being executed. The bigger number prints the more detailed information.
         • MDEBUG_INPUT -- If set to 1, print information about how an input method is running.
         • MDEBUG_ALL -- Setting this variable to 1 is equivalent to setting all the above variables to 1.
         • MDEBUG_OUTPUT_FILE -- If set to a file name, the above debugging information is appended to the file.
           If set to 'stdout', the information is printed to stdout.
       • Functions to print various objects in a human readable way. See the documentation of mdebug_dump_XXXX()
         functions.
       • The hook function called on an error. See the documentation of mdebug_hook().
