This lets the client of go/build specify additional tags that
can be recognized in a // +build directive. For example,
a build for a custom environment like App Engine might
include "appengine" in the BuildTags list, so that packages
can be written with some files saying
// +build appengine (build only on app engine)
or
// +build !appengine (build only when NOT on app engine)
App Engine here is just a hypothetical context. I plan to use
this in the cmd/go sources to distinguish the bootstrap version
of cmd/go (which will not use networking) from the full version
using a custom tag. It might also be useful in App Engine.
Also, delete Build and Script, which we did not end up using for
cmd/go and which never got turned on for real in goinstall.

Golden files have extension .d.golden where d is the mode value (0 or 1 for now)
(i.e., testdata/file.out is now testdata/file.0.golden, and there is a new file
testdata/file.1.golden for each testcase)

Document that indirection through a nil pointer will panic.
Explain function invocation.
This section will need more work, but it's a start.
Fixes#1865.
Fixes#2252.

Marshalling of []byte in attributes and the general
marshalling of named []byte types was fixed.
A []byte field also won't be nil if an XML element
was mapped to it, even if the element is empty.
Tests were introduced to make sure that *struct{}
fields works correctly for element presence testing.
No changes to the logic made in that regard.

It was 2^31, but that could cause overflow and trouble.
Reduce it to 2^30 and add a TODO.

I haven't looked at the source, but the gc compiler appears to
omit "not used" errors when there is an error in the
initializer. This is harder to do in gccgo, and frankly I
think the "not used" error is still useful even if the
initializer has a problem. This CL tweaks some tests to avoid
the error, which is not the point of these tests in any case.

It takes too much memory to be reliable and causes
trouble on 32-bit machines.
Sigh.

Make the panic detectable, and use that in ioutil.ReadFile to
give an error if the file is too big.

This fixes the bug Rob ran into when editing package bytes.
Regexp imports regexp/syntax, which imports bytes, and
regexp/syntax was not being properly recompiled during a
test of a change to package bytes.

This should make it easier to add the zillion little changes coming.
No content change here beyond a couple of introductory sentences.

summary: gc: fix infinite recursion for embedded interfaces
This is causing 'interface type loop' errors during compilation
of a complex program. I don't understand what's happening
well enough to boil it down to a simple test case, but undoing
this change fixes the problem.
The change being undone is fixing a corner case (uses of
pointer to interface in an interface definition) that basically
only comes up in erroneous Go programs. Let's not try to
fix this again until after Go 1.
Unfixes issue 1909.
