       Get an environment variable. The mtext_getenv() function searches the environment variable list for a
       string that matches the string pointed to by name.

       If there is a match, the function decodes the value according to the current locale (LC_CTYPE) into an
       M-text, and return that M-text.

       If there is no match, the function returns NULL.
