/*	The PHPFBLink structure represents a fbsql link. The lion is used for
	a connection to a machine, it may be persistent and is reference counted.
	The reason for refcounting is mostly to avoid to think, it work independent of 
	any wierd and unforseen allocation deallocation order.

	The PHPFBDatabse structure implements to actual connection to a FrontBase server
	ot may be persistent is the link it is connected to is persistent, and refcounted
	for the same reasons as above.

	The PHPFBResult structure implements a result from the FrontBase server, and does all
	required buffereing from of results.

	In the PHP code the 3 above a data structures are referenced by means of integers in the
	range from 1 to som configurable maximum. You can put a limit to the number of links, databases
	and results. The integer identifications is implemented by insertion in the list, which is passed
	as an argument to all the functions, please note the list is polymorph.

	Database objects and link objects are all reused, base on the host name user name, host name database name 
	user name. So connecting twice to the same database as the same user will return the same database id.
	We use the same coding for that as fbsql does, explioiting the underlying implementation of the lists.

	Persistent objects are put in the persistent list as well, but only by name, if you connect to a persistent object
	and it is not in the list it is simply added and get a new index, and refcounted. Tricky, tricky ...
