add cp437 and cp850 to available iconv conversions

perhaps some additional legacy DOS-era codepages would also be useful
to have, but these are the ones for which there has been demand. the
size of the diff is due to the fact that legacychars.h is updated in
such a way that new characters are inserted into the table in unicode
codepoint order; thus other mappings in codepages.h have changed to
reflect the new table indices of their characters.
