For both contended and uncontended case:
- support arbitrary number of cpus (not just 2)
- dynamic load balancing (improves stability)
- periodic execution of Gosched() to work around non-preemptiviness
For uncontended case eliminates possible false-sharing.
For contended case includes additional variation with some
amount of local work between mutex operations.

I have written up a Marshal and MarshalIndent pair that should
closely reflect the way that Unmarshal works. I would love feedback
on making this code more accessible and efficient... I haven't used
reflecton on this scale before, so there is probably a lot of work
that can be done on that.
Some potentially controversial things:
- All tag names are lower-cased by default.
- Zero-valued struct values are skipped.
- No namespace prefix (o:tag, etc) mechanism is supplied.
- You are allowed to marshal non-struct values (even though unmarshal
cannot handle them).
- A tag for a non-XMLName struct field that isn't "attr", "chardata",
or "innerxml" is used as the name of the tag. This could wreak
havoc if you try to marshal a protobuf struct.
- The "innerxml" and "chardata" are inserted verbatim. If you try to
marshal something straight from unmarshal, the results could be
unexpected (remove "innerxml" support from Marshal would be one
possible solution).

Reader previously had cached an error from the underlying reader
and would return it on every subsequent call to Read. The Reader
will now return the error only once, and subsequent calls will result
in a new Read call to the underlying Reader.

Users of the Scan() infrastructure that employ ReadRune() rather than
Token() need a way to skip leading spaces and newlines as set by the
the parent, Fscan(), Fscanln, or Fscanf(). As the internal methods and
boolean flags are not exported, this new function was added here and
in the Int and Nat Scan() functions of the big package. (fmt.Rat did
not need change since it uses Token()) Also added Printf style format
code support to int types and tests for same to int_test.go

As rsc suggested after change 58a6bdac3d12 was committed, we
now read the first byte of Request.Body when the
Request.ContentLength is 0 to disambiguate between a truly
zero-length body and a body of unknown length where the user
didn't set the ContentLength field.
This was also causing the reverse proxy problem where incoming
requests (which always have a body, of private type http.body,
even for 0-lengthed requests) were being relayed to the http
Transport for fetching, which was serializing the request as a
chunked request (since ContentLength was 0 and Body was
non-nil)

grsec needs the FIXED flag to be provided to mmap, which
works now. That said, when the allocation fails to be made
in the specific address, we're still given back a writable
page. This change will unmap that page to avoid using
twice the amount of memory needed.
It'd also be pretty easy to avoid the extra system calls
once we detected that the flag is needed, but I'm not sure
if that edge case is worth the effort.

This change causes Print et al. to catch panics generated by
calls to String, GoString, and Format. The panic is formatted
into the output stream as an error, but the program continues.
As a special case, if the argument was a nil pointer, the
result is just "<nil>", because that's almost certainly enough
information and handles the very common case of String
methods that don't guard against nil.
Scan does not want this change. Input must work; output can
be for debugging and it's nice to get output even when you
make a mistake.
