Add some missing include files

remove postgres.h from fmgr.h creation

won't be...

*should* be intelligent enough that:

#if defined(__FreeBSD__) works, where __FreeBSD__ is actually defined
by the compiler itself.

Makefile.global used to have -DPORTNAME_<port> -D<port> as part of the flags
for gcc while all occurances of PORTNAME_<port> slowly get removed from
the source tree...

removing duplicate names.

Adds:

    -lAttributes

        Returns another format of the results attribute list. Per
        attribute a sublist  of  {{attname}  atttype  attlen}  is
        returned  and  an  empty  string  if  no attributes where
        received.

    -numAttrs

        Returns the number of attributes in the result.

I found another bug in btree index.  Looking at the code it seems that NULL
keys are never used to build or scan a btree index (see the explain commands
in the example).  However this is not the case when a null key is retrieved
in an outer loop of a join select and used in an index scan of an inner loop.
This bug causes at least three kinds of problems:

1)  the backend crashes when it tries to compare a text string with a null.

2)  it is not possible to find tuples with null keys in a join.

3)  null is considered equal to 0 when the datum is passed by value, see
    the last query.
