Access security now supports IP address access groups (IPAG).

Up to now, channel access security allowed to specify access rules for clients
based on user- and host names.

This patch adds IP access groups. Now access rules may contain the client's IP
address too. The IP access group, "IPAG", can be used together with host access
groups, "HAG" or can replace these.

Notes for software that uses EPICS base:

This patch changes the API of the EPICS base channel access security library.
Users of the library must now provide the IP address of a client.

The following functions declared in asLib.h now have an additional parameter:

  asAddClient
  asChangeClient

In order to be able to write programs that support versions of EPICS base with
and without this patch, a new C macro is defined in file epicsVersion.h:

  #define EPICS_HAS_AS_IPAG 1
