Add support for <xti.h>

Applied.

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 <netinet/tcp.h>.
As a result, backend/libpq/pqcomm.c and interfaces/libpq/fe-connect.c
fail to compile.

The <netinet/tcp.h> header needs to be preceded by <netinet/in.h>, 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 <netinet/tcp.h> is a BSD header. The
correct header for TCP internals such as TCP_NODELAY on a UNIX system
is <xti.h>. By UNIX I mean UNIX95 (aka XPG4v2 or SUSv1) or later.
The current UNIX standard (UNIX98 aka SUSv2) is available online at
<http://www.opengroup.org/onlinepubs/7908799/&gt;.

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

The 2 files which conditionally include <netinet/tcp.h> need also to
conditionally include <xti.h>.

Patches follow.
