Remove the to_lower function; turns out that both uses of it

within the library were to perform case-insensitive matching, so
simply implement that instead.

Place all of the character set handling functions into a Charset
namespace (and update all callers).

Remove the iso2local/local2iso/iso2utf/utf2iso functions, replaced
by the new charset transcoder stuff.

Initialize the transcoder stored in the global library state
upon initialization.
