c48f2e3124 Improve error messages from to_tsquery per yesterday's discussion:
provide the bad input, and be sure to mention that we are talking about
a tsearch query.

8e5a10d46c This patch makes the error message strings throughout the backend
more compliant with the error message style guide. In particular,
errdetail should begin with a capital letter and end with a period,
whereas errmsg should not. I also fixed a few related issues in
passing, such as fixing the repeated misspelling of "lexeme" in
contrib/tsearch2 (per Tom's suggestion).

cb4ea994c6 Improve support of multibyte encoding:
- tsvector_(in|out)
- tsquery_(in|out)
- to_tsvector
- to_tsquery, plainto_tsquery
- 'simple' dictionary

436a2956d8 Re-run pgindent, fixing a problem where comment lines after a blank
comment line where output as too long, and update typedefs for /lib
directory.  Also fix case where identifiers were used as variable names
in the backend, but as typedefs in ecpg (favor the backend for
indenting).

Backpatch to 8.1.X.

c52795d18a Text parser rewritten:
- supports multibyte encodings
        - more strict rules for lexemes
        - flex isn't used
Add:
        - tsquery plainto_tsquery(text)
          Function makes tsquery from plain text.
        - &&, ||, !! operation for tsquery for combining
          tsquery from it's parts:  'foo & bar' || 'asd' => 'foo & bar | asd'

0645663e6c New features for tsearch2:
1 Comparison operation for tsquery
2 Btree index on tsquery
3 numnode(tsquery) - returns 'length' of tsquery
4 tsquery @ tsquery, tsquery ~ tsquery - contains, contained for tsquery.
  Note: They don't gurantee exact result, only MAY BE, so it
  useful only for speed up rewrite functions
5 GiST index support for @,~
6 rewrite():
        select rewrite(orig, what, to);
        select rewrite(ARRAY[orig, what, to]) from tsquery_table;
        select rewrite(orig, 'select what, to from tsquery_table;');
7 significantly improve cover algorithm

b492c3accc Add parentheses to macros when args are used in computations. Without
them, the executation behavior could be unexpected.

regression=# select to_tsquery( '\'fotballklubber\'');
                   to_tsquery
------------------------------------------------
 'fotball' & 'klubb' | 'fot' & 'ball' & 'klubb'
(1 row)

So, changed interface to dictionaries, lexize method of dictionary shoud return
pointer to aray of TSLexeme structs instead of char**. Last element should
have TSLexeme->lexeme == NULL.

typedef struct {
        /* number of variant of split word , for example
                Word 'fotballklubber' (norwegian) has two varian to split:
                ( fotball, klubb ) and ( fot, ball, klubb ). So, dictionary
                should return:
                nvariant        lexeme
                1               fotball
                1               klubb
                2               fot
                2               ball
                2               klubb

        */
        uint16  nvariant;

        /* currently unused */
        uint16  flags;

        /* C-string */
        char    *lexeme;
} TSLexeme;

1b3e769682 This patch makes some cleanups to contrib/ to silence some sparse
warnings:

- remove pointless "extern" keyword from some function definitions in
contrib/tsearch2

- use "NULL" not "0" as NULL pointer in contrib/tsearch,
contrib/tsearch2, contrib/pgbench, and contrib/vacuumlo
