dbaec70c15 Rename and slightly redefine the default text search parser's "word"
categories, as per discussion.  asciiword (formerly lword) is still
ASCII-letters-only, and numword (formerly word) is still the most general
mixed-alpha-and-digits case.  But word (formerly nlword) is now
any-group-of-letters-with-at-least-one-non-ASCII, rather than all-non-ASCII as
before.  This is no worse than before for parsing mixed Russian/English text,
which seems to have been the design center for the original coding; and it
should simplify matters for parsing most European languages.  In particular
it will not be necessary for any language to accept strings containing digits
as being regular "words".  The hyphenated-word categories are adjusted
similarly.

7ab43b88d7 Improve stylistic consistency of descriptions of built-in objects by avoiding
initcap style --- the vast majority of the existing descriptions do not use
an initial cap.  I didn't change places where the first word was all-cap.

initdb not forced because this doesn't change any regression test results.

7351b5fa17 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.

d321421d0a Simplify the syntax of CREATE/ALTER TEXT SEARCH DICTIONARY by treating the
init options of the template as top-level options in the syntax.  This also
makes ALTER a bit easier to use, since options can be replaced individually.
I also made these statements verify that the tmplinit method will accept
the new settings before they get stored; in the original coding you didn't
find out about mistakes until the dictionary got invoked.

Under the hood, init methods now get options as a List of DefElem instead
of a raw text string --- that lets tsearch use existing options-pushing code
instead of duplicating functionality.

140d4ebcb4 Tsearch2 functionality migrates to core. The bulk of this work is by
Oleg Bartunov and Teodor Sigaev, but I did a lot of editorializing,
so anything that's broken is probably my fault.

Documentation is nonexistent as yet, but let's land the patch so we can
get some portability testing done.
