Implement a facility for source file modularization in the VCL
 compiler.  The syntax is:
 
 	include "filename" ;
 
 Unlike the C preprocessors #include directive, a VCL include can
 appear anywhere in the sourcefile:
 
 	if {req.Cookie == include "cookie.vcl" ; || !req.Host } {
 	}
 
 and have cookie.vcl contain just:
 
 	"8435398475983275293759843"
 
 
 Technically this results in a change to how we account for source
 code references in the counter/profile table as well, and as a result
 the entire source code of the VCL program is now compiled into the
 shared library for easy reference.
