	Change vm->address_list from GSList to GQueue
	The current emulator uses an unbounded linked list for tracking the
	memory locations our program has traveled through. On a 64 bit system,
	this requires 16 bytes of data for every instruction a MIX program
	performs. For small programs that are light on computation cycles,
	this does not cause a noticeable issue.

	For programs that execute hundreds of millions of instructions, this
	causes the memory footprint of the virtual machine to explode. I have
	attached an example MIXAL program that will cause the VM to grow to
	over 3 GB of memory usage when run.

	To run the sample, compile coin-opt.mixal (attached), run it in mixvm,
	and enter 499 at the prompt. Or use the following steps.

	This patch changes all the appropriate references to GQueue references
	and also caps the backtrace at 1000, which can be changed in the
	mixlib/mix_vm.h header. I feel like 1000 is a reasonable limit for the
	vast majority of debugging needs. Most people are looking back at the
	most recent 100 instructions or so.

	You can get the original behavior (unlimited tracing) back by setting
	the MIX_MAXTRACE to -1, albeit with a slightly higher memory cost (24
	bytes per instruction). Or you can turn it off entirely by setting it
	to 0.

	Using a queue doesn't change the logic of the program in any
	significant way, and it allows programs to run for an extended period
	of time without consuming all the memory on the machine and slowing
	down to a crawl.

	GTK Console input no longer overruns buffer
	Patch by Kevin Brunelle

	The console input in gmixvm will only read 70 characters, but the
	outer loop used 70 (the characters) instead of 14 (the number of
	words). This caused the VM to read past the end of the buffer and
	write 56 words of junk into the emulator.

	Support IOC commands for disk/drum devices
	Thanks to Kevin Brunelle

	There is a minor fix included with regards to tape devices. The test
	was failing if M == 0, when it should fail when M != 0.

	NOTICE: This patch changes the behavior of the VM and changes the
	function parameters for the ioc_ function. Documentation changes are
	included.

	Permits the following:
	     LDX   BLKNUM
	     IOC   0(8)
	     OUT   ADDR(8)      Write block from ADDR into disk[BLKNUM]
	     IOC   0(8)
	     IN    ADDR(8)      Read block from disk[BLKNUM] into ADDR
	...
	BLKNUM  CON  45000      Example possible block on disk

	I was having an issue writing a block to a drive and then reading back
	the same block. Because it is impossible to move the SEEK_CUR pointer
	backwards on a disk device, there was no way for a program to read
	back a block that it wrote to a disk without restarting or fiddling
	with ~/.mdk/disk?.dev files and symbolic links.

	I have added a function parameter to the ioc_ function and used it to
	pass the value of rX to ioc_. This permits us to use IOC commands to
	move the read/write head on a disk/drum device. I believe that this
	conforms to the potential meaning of Knuth's description of IOC for
	disk/drum devices.

	I have put in tests to verify that rX is positive and M = 0.

	I have updated the documentation to reflect this new behavior.

	This makes disks much more usable.

	Note: I won't be offended if this patch is rejected because it changed
	the behavior of the VM. I think it fits the spirit and enhances the
	functionality in a way that some might find useful. I wanted it for
	something I was working on, and I felt others might want the same. The
	thing with the paper-tape should be fixed, though.

	NEWS and version bump

2019-03-20  Jose Antonio Ortega Ruiz  <jao@gnu.org>

	Fix: correctly rewind tape
	According to the specification, if M < 0, the tape is skipped backwards M
	blocks, or to the beginning of the tape, whichever comes first.  In the
	implementation, we don't check to verify that we aren't seeking past the
	beginning of the file. This causes fseek(3) to fail, and it leaves us at the
	position we were at.

	Diagnosis and fix by Kevin Brunelle.
