Add REGEX built-in function to support regular expressions

We would like to have regular expressions available via a built-in function with the following syntax:

rc = REGEX( index, length, pattern, string, [ , start ] [ , codepage ] );

The function sets the value for the <index> and <length> of the first substring in <string> that matches the regular expression <pattern> where:

- The optional <start> specifies where the processing begins (default is 1)
- The optional <codepage> specifies the code page used by the <string> and <pattern> (default is the value of the compiler CODEPAGE option)

This function encapsulates the C functions regcomp, regexec and regfree:

- regcomp will be called once for every “new” regular expression in a program execution and regcomp output will be cached.
- regexec will be called with using this cache.
- At the end of the program, regfree will be called automatically to free this cache.
