pcf: Fix some data types mismatching with their sources.
* src/pcf/pcfdrivr.c (pcf_cmap_char_index): The type of
`code' is matched to PCF_Encoding->enc.
(pcf_cmap_char_next): The type of `charcode' is matched
to PCF_Encoding->enc. When *acharcode is set by charcode,
an overflow is checked and casted to unsigned 32-bit
integer.
