Fully update git head, and update back branches in ./COPYRIGHT and
legal.sgml files.

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.

Probably no practical impact, since all pointers ought to have the
same size, but it was wrong nonetheless. Found by Coverity.

This addresses only those cases that are easy to fix by adding or
moving a const qualifier or removing an unnecessary cast. There are
many more complicated cases remaining.

This applies the fix for bug #5784 to remaining places where we wish
to reject nulls in user-supplied arrays. In all these places, there's
no reason not to allow a null bitmap to be present, so long as none of
the current elements are actually null.
I did not change some other places where we are looking at system catalog
entries or aggregate transition values, as the presence of a null bitmap
in such an array would be suspicious.

Per C standard, these are semantically the same thing; but saying NULL
when you mean NULL is good for readability.

This alters various incidental uses of C++ key words to use other similar
identifiers, so that a C++ compiler won't choke outright. You still
(probably) need extern "C" { }; around the inclusion of backend headers.
based on a patch by Kurt Harriman <harriman@acm.org>
Also add a script cpluspluscheck to check for C++ compatibility in the
future. As of right now, this passes without error for me.

of this seems a bit marginal, if it's useful enough to be shown in the manual
then we probably ought to support doing it without double evaluation of the
ts_rank function. Per my proposal earlier today.

(ts_rank_cd). Use palloc'ed array in ranking instead of flag.

* Defined new struct WordEntryPosVector that holds a uint16 length and a
variable size array of WordEntries. This replaces the previous
convention of a variable size uint16 array, with the first element
implying the length. WordEntryPosVector has the same layout in memory,
but is more readable in source code. The POSDATAPTR and POSDATALEN
macros are still used, though it would now be more readable to access
the fields in WordEntryPosVector directly.
* Removed needfree field from DocRepresentation. It was always set to false.
* Miscellaneous other commenting and refactoring

- 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.

- add code to check that the query tree is well-formed. It was indeed
possible to send malformed queries in binary mode, which produced all
kinds of strange results.
- make the left-field a uint32. There's no reason to
arbitrarily limit it to 16-bits, and it won't increase the disk/memory
footprint either now that QueryOperator and QueryOperand are separate
structs.
- add check_stack_depth() call to all recursive functions I found.
Some of them might have a natural limit so that you can't force
arbitrarily deep recursions, but check_stack_depth() is cheap enough
that seems best to just stick it into anything that might be a problem.

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.
