234163649e GIN improvements
- Replace sorted array of entries in maintenance_work_mem to binary tree,
  this should improve create performance.
- More precisely calculate allocated memory, eliminate leaks
  with user-defined extractValue()
- Improve wordings in tsearch2

22505f4703 Add thesaurus dictionary which can replace N>0 lexemes by M>0 lexemes.
It required some changes in lexize algorithm, but interface with
dictionaries stays compatible with old dictionaries.

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).

278bd0cc22 For some reason access/tupmacs.h has been #including utils/memutils.h,
which is neither needed by nor related to that header.  Remove the bogus
inclusion and instead include the header in those C files that actually
need it.  Also fix unnecessary inclusions and bad inclusion order in
tsearch2 files.

324300bc7c improve support of agglutinative languages (query with compound words).
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;

6000e32805 I've not changed any malloc/calloc to palloc. It looks to me that these memory
areas are for the lifetime of the backend and in the interests of not breaking
something that's not broken I left alone.

Note for anyone reading this and wanting it for tsearch-v2-stable (i.e. for 7.3
backend) this patch probably will not apply cleanly to that source. It should
be simple enough to see what's going on and apply the changes by hand if need
be.

0b1ee9b5a3 fix hlfinditem function. Thanks to "Stphane Bidoul" <stephane.bidoul@softwareag.com>.
The 'word' variable there is initialised from
the prs->words array, but immediately after,
that array may be reallocated, thus leaving
word pointing to unallocated memory.
