Backpatch-through: certain files through 9.3

pq_sendint() remains, so extension code doesn't unnecessarily break.

Gen_fmgrtab.pl creates a new file fmgrprotos.h, which contains
prototypes for all functions registered in pg_proc.h. This avoids
having to manually maintain these prototypes across a random variety of
header files. It also automatically enforces a correct function
signature, and since there are warnings about missing prototypes, it
will detect functions that are defined but not registered in
pg_proc.h (or otherwise used).

Rename comparePos() to compareWordEntryPos() to prevent export of too
generic name.

Patch introduces new text search operator (<-> or <DISTANCE>) into tsquery.
On-disk and binary in/out format of tsquery are backward compatible.
It has two side effect:
- change order for tsquery, so, users, who has a btree index over tsquery,
should reindex it
- less number of parenthesis in tsquery output, and tsquery becomes more
readable

The behavior of that is undefined, although unlikely to lead to problems in
practice.
Found by running regression tests with Valgrind.

The latter was already the dominant use, and it's preferable because
in C the convention is that intXX means XX bits. Therefore, allowing
mixed use of int2, int4, int8, int16, int32 is obviously confusing.
Remove the typedefs for int2 and int4 for now. They don't seem to be
widely used outside of the PostgreSQL source tree, and the few uses
can probably be cleaned up by the time this ships.

The input should've been validated well before it hits the input function.
Doing so again is a waste of cycles.

Basically, it's needed to support binary dump from 8.3 because ordering rule
was changed.

miscomputation of required palloc size. The crash could only occur if the
input contained lexemes both with and without positions, which is probably not
common in practice. The miscomputation would definitely result in wasted
space. Also fix some inconsistent coding around alignment of strings and
positions in a tsvector value; these errors could also lead to crashes given
mixed with/without position data and a machine that's picky about alignment.
And be more careful about checking for overflow of string offsets.
Patch is only against HEAD --- I have not looked to see if same bugs are
in back-branch contrib/tsearch2 code.

too. Make styles of some related error messages more consistent.

- change the alignment requirement of lexemes in TSVector slightly.
Lexeme strings were always padded to 2-byte aligned length to make sure
that if there's position array (uint16[]) it has the right alignment.
The patch changes that so that the padding is not done when there's no
positions. That makes the storage of tsvectors without positions
slightly more compact.
- added some #include "miscadmin.h" lines I missed in the earlier when I
added calls to check_stack_depth().
- Reimplement the send/recv functions, and added a comment
above them describing the on-wire format. The CRC is now recalculated in
tsquery as well per previous discussion.

small editorization by me
- Brake the QueryItem struct into QueryOperator and QueryOperand.
Type was really the only common field between them. QueryItem still
exists, and is used in the TSQuery struct as before, but it's now a
union of the two. Many other changes fell from that, like separation
of pushval_asis function into pushValue, pushOperator and pushStop.
- Moved some structs that were for internal use only from header files
to the right .c-files.
- Moved tsvector parser to a new tsvector_parser.c file. Parser code was
about half of the size of tsvector.c, it's also used from tsquery.c, and
it has some data structures of its own, so it seems better to separate
it. Cleaned up the API so that TSVectorParserState is not accessed from
outside tsvector_parser.c.
- Separated enumerations (#defines, really) used for QueryItem.type
field and as return codes from gettoken_query. It was just accidental
code sharing.
- Removed ParseQueryNode struct used internally by makepol and friends.
push*-functions now construct QueryItems directly.
- Changed int4 variables to just ints for variables like "i" or "array
size", where the storage-size was not significant.

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.
