Robert Griesemer d08dd8bec1 go/scanner: clean up error interface
Issue 2856 asks for a rename of a few methods to a
more idiomatic Go style. This is a very early API
that evolved organically throughout the years.
Together with the fact that ErrorVectors were embedded
in other data structures (e.g. Parser), just renaming
methods (e.g. GetError -> Error) would lead to undesired
behavior (e.g., Parser would act like an Error). Instead,
cleaned up API a bit more:

- removed ErrorVector in favor of ErrorList (already
present)
- simplified Scanner.Init by making the error handler a
function instead of requiring an ErrorHandler implementation
- adjusted helper functions accordingly
- updated Go 1 doc

Fixes #2856.

Paul Borman d37a8b73c5 runtime: drop to 32 bit malloc if 64 bit will not work
On 64 bit UML it is not possible to reserve memory at 0xF8<<32.
Detect when linux cannot use these high virtual memory addresses
and drop back to the 32 bit memory allocator.

Russ Cox d0dc68901a net/http: panic on duplicate registrations
Otherwise, the registration semantics are
init-order-dependent, which I was trying very hard
to avoid in the API.  This may break broken programs.

Russ Cox 1d8250c8b0 time: clean up MarshalJSON, add RFC3339 method
encoding/xml: handle time.Time as recognized type

The long term plan is to define an interface that time.Time
can implement and that encoding/xml can call, but we are
not going to try to define that interface before Go 1.
Instead, special-case time.Time in package xml, because
it is such a fundamental type, as a stop-gap.
The eventual methods will behave this way.

Fixes #2793.

Rob Pike 52ebadd356 encoding/binary: hide TotalSize
The function has a bizarre signature: it was the only public function there

explain. It doesn't merit being exported.

This is an API change but really, it should never have been exported and
it's certain very few programs will depend on it: it's too weird.

Robert Griesemer 3d6b368514 go/printer, gofmt: don't print incorrect programs
Be careful when printing line comments with incorrect
position information. Maintain additional state
impliedSemi: when set, a comment containing a newline
would imply a semicolon and thus placement must be
delayed.

Precompute state information pertaining to the next
comment for faster checks (the printer is marginally
faster now despite additional checks for each comment).

No effect on existing src, misc sources.

Right now, GOTRACEBACK=0 means do not show any stack traces.
Unset means the default behavior (declutter by hiding runtime routines).

the runtime in the tracebacks.
