was adding -DNOVERSION -DINIT to wrong variable

* The transport between the Maiko client and Nethub server is TCP based and therefore data is buffered by the kernel so it is not necessary to have an additional layer of buffering to capture multiple logical packets before passing them to the Lisp ethernet interrupt handler.

  * Receive packet directly into Lisp’s buffer and byte-swap in place only if necessary.

  * Ethernet packet handling is no longer done directly in the signal handler so it is not necessary to block/unblock signals while a packet is being read from the byte stream in ether_get().

  * Remove references to ETHEREventCount as it is unnecessary and the implementation (xc.c; other ethernet handlers) that attempted to use it to handle missed ethernet interrupts is incorrect, resulting in calls to the Lisp interrupt handler with no new packet data.

  * Style changes - Use early return rather than nesting if statements.  Move variable declarations from inline to beginning of function if they are not local to a small block. Use %p format specifier for printing pointers.

@@ -124,9 +124,37 @@ BIGATOMS	True if this emulator will support 3-byte symbols, instead of
 NEWBITBLT	True if we want to use assembler BITBLT code, rather than
 		have code created inline by macro calls.
 
+USE_DLPI	True if the ethernet API is via the SysV Data Link Provider
+		Interface.  Solaris uses DLPI.
+
+USE_NIT		True if the ethernet API is via the Network Interface Tap.
+		SunOS uses NIT.
+
+PKTFILTER	True if the ethernet packets are to be filtered before being
+		passed to the Lisp ethernet handler.  Available on Sun systems
+		for both the NIT and DLPI cases.
+
+MAIKO_ENABLE_NETHUB enables the support for Dodo Nethub networking for Dodo
+		XNS services, see documentation: using-dodo-networking-with-maiko.md
+		(implicitely disables USE_DLPI and USE_NIT)
+
+MAIKO_EMULATE_TIMER_INTERRUPTS enables emulation of recurring timer interrupts for
+		platforms where SIGVTALRM/ITIMER_VIRTUAL or SIGALRM/ITIMER_REAL
+		do not work as expected (like cygwin)
+		timer is emulated by signaling an interrupt after a number of
+		executed instructions, by default 20.000 instructions, this can be
+		overriden by defining MAIKO_TIMER_ASYNC_EMULATION_INSNS_COUNTDOWN
+		with the number of instructions between 2 interrupts
+		additionally this adds the command line arguments -intr-emu-insns
+		for overriding the compiled in instruction interval
+		(not working if OPDISP (fast opcode dispatch) is used)
+
+MAIKO_EMULATE_ASYNC_INTERRUPTS same as MAIKO_EMULATE_TIMER_INTERRUPTS, but also
+		signals an I/O interrupt after each instruction interval

+# Using Dodo-networking with Maiko
+
+The [Dodo XNS services](https://github.com/devhawala/dodo) provide an emulation for a usable
+subset of the Xerox 8000 Network Services from the 1980-ies. Dodo uses its own virtual
+network infrastructure - the Dodo *Nethub* - for avoiding the problems involved with
+implementing the transmission of XNS protocol packets over (real or virtual) network
+adapters of the diverse contemporary operating systems.
+
+The Dodo Nethub provides a simple virtual network, a kind of *XNS-over-TCP/IP*,
+where clients and servers connect with TCP/IP to the central Nethub program, which relays all
+packets ingoing from one connection to the other connections.
+
+The following sections describe the support for Dodo-networking added to
+Maiko. The Dodo Nethub support was implemented and tested with Linux on the x86_64
+architecture. However as only standard system calls for TCP/IP were used, adapting to other
+platforms if necessary should be possible.
+
+This extension allows Medley 3.51 running in a Maiko VM to use the XNS services
+*Clearinghouse*, *Filing* and *Printing* provided by Dodo (using the *Mail* service may
+also be possible, but this was not verified so far)  
+
+## Building Maiko with Dodo-networking support
+
+As long as Dodo-networking support is not merged into the `master`-branch
+of the primary Maiko repository, this networking option is only available in this
+clone of the original Maiko repository in the branch `dodo-nethub-support`.    
+(however: this branch should already be checked out if this file is present)
+
+The Dodo-networking support is enabled by defining `MAIKO_ENABLE_NETHUB`
+when compiling Maiko. This can be done in the Makefile for the relevant platform
+(file `bin/makefile-`*platform*) for example in the line where the compiler-command
+variable is defined.
+
+This is already done in the Makefile for the *Linux-x86_64-X* platform (file
+`bin/makefile-linux.x86_64-x`), where the compiler-command defined as follows:
+
+```
+CC = clang -m64 $(CLANG_CFLAGS) -DMAIKO_ENABLE_NETHUB
+```
+
+After a complete (re-)build, this Maiko VM optionally allows to connect to a Dodo Nethub
+and through this to use Dodo XNS services.
+  
+
+## Running Maiko with Dodo-networking
+
+With Dodo-networking support compiled in, Maiko (i.e. the program `ldex`) accepts the
+following additional commandline options:
+
+- `-nh-host` *dodo-host*    
+  the name or IP-address of the host where the Dodo Nethub program runs; no connection to
+  Dodo services will be opened if this option is not specified    
+  Default: (*none*)
+
+- `-nh-port` *port-number*    
+  the port which the Dodo Nethub is listening to at *dodo-host*    
+  Default: `3333`
+
+- `-nh-mac` *machine-id*    
+  the machine-id (aka. MAC-address) that this Maiko VM instance will use in the Dodo network;
+  the machine-id must be given as 48 bit hexadecimal value with a dash as byte-separator, i.e.
+  in the format *XX-XX-XX-XX-XX-XX* (with *XX* the hexcode for a single byte)     
+  Default: `CA-FF-EE-12-34-56`
+
+- `-nh-loglevel` *log-level*    
+  the detail level of logging to `stdout`, one of:    
+  `0`: log only main events (connect, disconnect or the like)    
+  `1`: log network events each with a single line    
+  `2`: detailled log of network events    
+  Default: `0`
+
+So by default Maiko will not connect to a Dodo nethub and behave like a "standard" version
+without networking support.    
+To use Dodo XNS services, the option `-nh-host` must be given to specify the location
+of the Dodo nethub. In the simplest (and probably most usual) case where Dodo is run on the
+same machine as Maiko/Medley, the value for option `-nh-host` will be *localhost*, so
+adding the option `-nh-host localhost` when starting the Medley Lisp system will allow
+to use the XNS services of a Dodo system running locally.  
+
+Specifying the *machine-id* is optional unless more than one Maiko/Medley instances are to use
+Dodo XNS services concurrently: in this case, each Maiko VM *must* use a *unique* machine-id,
+so at most one Maiko VM may omit the `-nh-mac` option.    
+However, each machine-id used by the Maiko VMs should have an entry in the `machine.cfg`
+file of the Dodo installation, cloning or copying the low-level SPP-configuration of the
+`maiko-Lisp-One` example entry in the `machine.cfg` of the Dodo `dist.zip`
+distribution.
