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.

init-order-dependent, which I was trying very hard

This changes makes constant propagation compare 'from' values using node
pointers rather than symbol names when checking to see whether a set
operation is redundant. When a function is inlined multiple times in a
calling function its arguments will share symbol names even though the values
are different. Prior to this fix the bug409 test would hit a case with 6g
where an LEAQ instruction was incorrectly eliminated from the second inlined
function call. 8g appears to have had the same bug, but the test did not fail
there.

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.
