Altered NSAPI autoconf to check for location of include files automatically, tested for Netscape 3.x and iPlanet 4.x.

Added very basic variable support for usefull things such as PHP_SELF. I'll extend this to supply this rest of the variables soon.
Commited a patch to activate ZTS in the NSAPI module, this patch comes from
Jayakumar Muthukumarasamy.

+Configuration of your Netscape or iPlanet Web Server for PHP4
+-------------------------------------------------------------
+
+These instructions are targetted at Netscape Enterprise Web Server
+and SUN/Netscape Alliance iPlanet Web Server. On other web servers
+your milage may vary.
+
+Firstly you may need to add some paths to the LD_LIBRARY_PATH
+environment for netscape to find all the shared libs. This is
+best done in the start script for your netscape server.
+Windows users can probably skip this step. The start
+script is located in:
+<path-to-netscape-server>/https-servername/start
 
 netscape config files are located in:
-/netscape/suitespot/httpd-servername/config
+<path-to-netscape-server>/https-servername/config
 
 add the following line to mime.types
 
 type=magnus-internal/x-httpd-php	exts=php
 
 
-Add the following to obj.conf
+Add the following to obj.conf, shlib will vary depending on your OS, for unix it
+will be something like "<path-to-netscape-server>/bin/libphp4.so".
 
 #note place following two lines after mime types init!
 Init fn="load-modules" funcs="php4_init,php4_close,php4_execute,php4_auth_trans" shlib="/php4/nsapiPHP4.dll"
