Instead of always reading from a table, give the charset a chance to
implement tolower() and toupper() algorithmically.
This allow us to drop a lot of tables which hardcode the identity
functions (like ASCII), and replace them with a few lines of code in the
hooks.
This patch was created using the semantic patch below, with the
exception of the header files (hook definitions) and a fix to files that
didn't have the tables statically allocated (koi8-u and cp932).
