0442087f93 encoding/xml: bring API closer to other packages
Includes gofix module. The only case not covered should be
xml.Unmarshal, since it remains with a similar interface, and
would require introspecting the type of its first argument
better.

1dc37bbf46 math/big: slight improvement to algorithm used for internal bitLen function
The bitLen function currently shifts out blocks of 8 bits at a time.
This change replaces this sorta-linear algorithm with a log(N)
one (shift out 16 bits, then 8, then 4, then 2, then 1).
I left the start of it linear at 16 bits at a time so that
the function continues to work with 32 or 64 bit values
without any funkiness.
The algorithm is similar to several of the nlz ("number of
leading zeros") algorithms from "Hacker's Delight" or the
"bit twiddling hacks" pages.

Doesn't make a big difference to the existing benchmarks, but
I'm using the code in a different context that calls bitLen
much more often, so it seemed worthwhile making the existing
codebase faster so that it's a better building block.

ed936a3f22 cmd/go: implement go get + bug fixes
Move error information into Package struct, so that
a package can be returned even if a dependency failed
to load or did not exist.  This makes it possible to run
'go fix' or 'go fmt' on packages with broken dependencies
or missing imports.  It also enables go get -fix.
The new go list -e flag lets go list process those package
errors as normal data.

Change p.Doc to be first sentence of package doc, not
entire package doc.  Makes go list -json or
go list -f '{{.ImportPath}} {{.Doc}}' much more reasonable.

The go tool now depends on http, which means also
net and crypto/tls, both of which use cgo.  Trying to
make the build scripts that build the go tool understand
and handle cgo is too much work.  Instead, we build
a stripped down version of the go tool, compiled as go_bootstrap,
that substitutes an error stub for the usual HTTP code.
The buildscript builds go_bootstrap, go_bootstrap builds
the standard packages and commands, including the full
including-HTTP-support go tool, and then go_bootstrap
gets deleted.

Also handle the case where the buildscript needs updating
during all.bash: if it fails but a go command can be found on
the current $PATH, try to regenerate it.  This gracefully
handles situations like adding a new file to a package
used by the go tool.

b5777571b3 go/build: add BuildTags to Context, allow !tag
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.

387e7c2742 test: explicitly use variables to avoid gccgo "not used" error
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.
