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;
typedef struct {} WordEntryPos;
to
typedef uint16 WordEntryPos

Require re-fill all tsvector fields and reindex tsvector indexes.
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
