Cleanup for some problems in tsearch patch:
- ispell initialization crashed on empty dictionary file - ispell initialization crashed on affix file with prefixes but no suffixes - stop words file was run through pg_verify_mbstr, with database encoding, but it's supposed to be UTF-8; similar bug for synonym files - bunch of comments added, typos fixed, and other cleanup Introduced consistent encoding checking/conversion of data read from tsearch configuration files, by doing this in a single t_readline() subroutine (replacing direct usages of fgets). Cleaned up API for readstopwords too. Heikki Linnakangas
