Not a complete fix for issue 3342, but fixes the trivial case.
There may still be a race in the instants before and after
a scavenger-induced garbage collection.

Intended to be "obviously safe": a call to runtime·gosched
before main.main is no different than a call to runtime.Gosched
at the beginning of main.main, and it is (or had better be)
safe to call runtime.Gosched at any point during main.

Update #3342.

Another attempt at https://golang.org/cl/5754088.

Before, we only consulted $GOBIN for source code
found in $GOROOT, but that's confusing to explain
and less useful.  The new behavior lets users set
GOBIN=$HOME/bin and have all go-compiled binaries
installed there.

Tested a few cases in test.bash.

Ran all.bash with and without $GOBIN and it works.
Even so, I expect it to break the builders,
like it did last time, we can debug from there.

Fixes #3269 (again).
Fixes #3396.
Fixes #3397.

When we find a package in DIR/src/foo, we only let it
be known as foo if there is no other foo in an earlier
GOPATH directory or the GOROOT directory.
The GOROOT check was looking in GOROOT/src/foo
instead of GOROOT/src/pkg/foo, which meant that
the import paths "lib9", "libbio", "libmach", and so
on were unavailable, and the import paths "math",
"errors", and so on were available.  Correct this.

Fixes #3390.

Issue 3207 was caused by setting GOPATH=GOROOT.
This is a common mistake, so diagnose it at command start
and also correct the bug that it caused in get (downloading
to GOROOT/src/foo instead of GOROOT/src/pkg/foo).

Issue 3268 was caused by recognizing 'packages' that
had installed binaries but no source.  This behavior is not
documented and causes trouble, so remove it.  We can
revisit the concept of binary-only packages after Go 1.

Fixes #3207.
Fixes #3268.

- Renamed ExportData -> FindGcExportData
  and base it on an a bufio.Reader rather
  than a filename so it can be used in
  environments where object files are
  stored elsewhere.

- Factor former GcImporter into GcImportData
  and GcImport. Implementations with different
  storage locations for object files can build
  a customized GcImport using GcImportData.

This is pkg/exp only - no impact on Go 1.

The heading "Copyright" uses id="copyright" as the anchor name.
However, there is also a <div id="copyright"> at the bottom.
