1b96ef4b0d Clarify mdb_unicode2ascii API and fix buffer overrun (#220) 
There was some confusion as to whether the destination buffer length
should include space for the null terminator. Some callers of the
function assumed that a terminator would be added beyond the end
of the stated buffer size, while others did not. Make everything
consistent and also fix an overrun when there was insufficient
space for the output in the non-iconv implementation.

As stated in a code comment, a better solution would follow the lead
of libxls and use wcstombs and friends when iconv is not available.
But this gets into the weeds with conversion functions named differently
across platforms. The goal here is to fix the buffer overrun.

eb39a483a3 Remove long-deprecated functions 
mdb_init() and mdb_exit() have done nothing for a while.

mdb_get_coltype_string() and mdb_coltype_takes_length() were previously
removed, but remained in the header file by accident.
