Add support for <xti.h>

                        POSTGRESQL BUG REPORT TEMPLATE
============================================================================

System Configuration
---------------------
  Architecture (example: Intel Pentium)  	: SGI MIPS 8000

  Operating System (example: Linux 2.0.26 ELF) 	: IRIX 6.5.5m

  PostgreSQL version (example: PostgreSQL-7.1):   PostgreSQL-7.1

  Compiler used (example:  gcc 2.8.0)		: MIPSPro 7.3

  NB: I expect that the same problem would arise on AIX and Solaris.

Please enter a FULL description of your problem:
------------------------------------------------

The configure script fails to find .
As a result, backend/libpq/pqcomm.c and interfaces/libpq/fe-connect.c
fail to compile.

The  header needs to be preceded by , at
least on IRIX, Solaris and AIX.  The simple configure test fails.
(That header on Linux is idempotent.)


Please describe a way to repeat the problem.   Please try to provide a
concise reproducible example, if at all possible: 
----------------------------------------------------------------------

$ configure
...
checking for netinet/tcp.h... no
...

$ make
...
cc-1020 cc: ERROR File = pqcomm.c, Line = 346
  The identifier "TCP_NODELAY" is undefined.

  		if (setsockopt(port->sock, IPPROTO_TCP, TCP_NODELAY,
  		                                        ^

1 error detected in the compilation of "pqcomm.c".
...


If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------

The basic problem is that  is a BSD header.  The
correct header for TCP internals such as TCP_NODELAY on a UNIX system
is .  By UNIX I mean UNIX95 (aka XPG4v2 or SUSv1) or later.
The current UNIX standard (UNIX98 aka SUSv2) is available online at
.

The fix is to add header support for  into configure.in and
config.h.in.

The 2 files which conditionally include  need also to
conditionally include .

Patches follow.
