- complex numbers now supported.
- entirely independent of standard decode code.
- parser has no read-ahead; that is, the scanning works
simply by reading the values as they arrive, not by trying
to count bytes for message boundaries, a proof of concept
for the pending rewrite of the regular decoder.

The linker avoids a GOT indirection by turning a MOV into
a LEA, but with x86-64 GCC has started emitting CMOV*
instructions which break the existing logic.
This will generate errors such as:
unexpected GOT reloc for non-dynamic symbol luaO_nilobject_
The CMOV* instructions may be emitted with normal code like:
if (o >= L->top) return cast(TValue *, luaO_nilobject);
else return o;
Which gets compiled into (relocation offset at 1b):
13: 48 3b 47 10 cmp 0x10(%rdi),%rax
17: 48 0f 43 05 00 00 00 cmovae 0x0(%rip),%rax
1e: 00
This change will allow the indirection through the GOT to
avoid the problem in those cases.

The implementation of the position computation
was surprisingly broken. Implemented fixes and
added extra test cases.
There is a slight interface change: Calling
Pos() returns the current position; but if
called before Scan() that position may not
be the position of the next token returned
by Scan() (depending on the scan settings
and the source text) - this in contrast to
the original comment.
However, after calling Scan(), the Scanner's
Position field reports the position of the
scanned token, as before.

The test code used to do this:
for _, tc := range tests {
ch <- &tc
}
Note that &tc is always the same value here. As the value is
received from the channel, the sender can loop around and

value is unstable and can change while it is in use.

The o+i*p approach to visiting select cases in random
order stops being fair when there is some case that
is never ready. If that happens, then the case that follows
it in the order gets more chances than the others.
In general the only way to ensure fairness is to make
all permutations equally likely. I've done that by computing
one explicitly.
Makes the permutations correct for n >= 4 where
previously they were broken. For n > 12, there's not
enough randomness to do a perfect job but this should
still be much better than before.

With the current implementation, xml unmarshalling
will silently fail to unmarshal any paths passing
through the same element, such as:
type T struct {
A string "dummy>a"
B string "dummy>b"

This change tweaks the algorithm so that this works
correctly.
Also, using paths that would cause the same element to
unmarshal twice will error out ahead of time explaining
the problem, rather than silently misbehaving.

When data is received for a channel, but that channel
is not ready to receive it, the central run() loop
is currently blocked, but this can lead to deadlock
and interference between independent channels.
This CL adds an explicit buffer size to netchan
channels (an API change) - the sender will not
send values until the buffer is non empty.
The protocol changes to send ids rather than channel names
because acks can still be sent after a channel is hung up,
we we need an identifier that can be ignored.

The ARM code was inconsistent about whether the
"argument frame" included the saved LR. Including it made
some things more regular but mostly just caused confusion
