Two tests start a goroutine which runs exportSend, and then
the tests run importReceive.  exportSend creates an export
channel.  importReceive asks to receive values on that
channel.  Because exportSend runs in a separate goroutine,
it's possible for the export client to receive the request for
values on the channel, from importReceive, before the
goroutine actually creates the export channel.  That causes an
error: "export: no such channel: exportedSend".  This patch
avoids the race by creating the export channel before starting
the goroutine.

There does not seem to be a similar race condition in the
tests which send data in the other direction.

End the charade (farce?) that we are using upload.py unaltered.
Cut all the unused stuff.
Indent using tabs to match the rest of the file.

Next: rewrite MercurialVCS to use mercurial package,
to avoid overhead of forking off a new hg command
multiple times for every file.  And parallelize upload.

- refine/define Scope, Object, and Type structures
  (note: scope.go has the addition of types, the rest is only re-organized
  for better readability)
- implemented top-level of type checker:
  resolve global type declarations (deal with double decls, cycles, etc.)
- temporary hooks for checking of const/var declarations, function/method bodies
- test harness for fine-grained testing (exact error locations)
  with initial set of tests

This is a subset of the code for easier review.

Based on the observation that a great number of the types that
are copied or compared in interfaces, maps, and channels are
word-sized, this uses specialized copy and equality functions
for them that use a word instead of 4 or 8 bytes. Seems to yield
0-6% improvements in performance in the benchmarks I've run.
For example, with the regexp benchmarks:

Before:
regexp.BenchmarkLiteral   500000       3.26 µs/op
regexp.BenchmarkNotLiteral    100000      13.67 µs/op
regexp.BenchmarkMatchClass    100000      18.72 µs/op
regexp.BenchmarkMatchClass_InRange    100000      20.04 µs/op
regexp.BenchmarkReplaceAll    100000      27.85 µs/op

After:
regexp.BenchmarkLiteral   500000       3.11 µs/op
regexp.BenchmarkNotLiteral    200000      13.29 µs/op
regexp.BenchmarkMatchClass    100000      17.65 µs/op
regexp.BenchmarkMatchClass_InRange    100000      18.49 µs/op
regexp.BenchmarkReplaceAll    100000      26.34 µs/op

Commands written in Go depend on Go packages, so they
cannot be built by src/cmd/make.bash.  They have been
built by src/make.bash after all the packages are done, but
we want to be able to use cgo (written in Go) during the build
of package net.  To make this possible, build the commands
from src/pkg/Makefile instead of src/make.bash, so that they
are included in the package dependency analysis.

Despite the name, URL escaping is for a small subpiece of the URL only.
This particular URL is being emitted in an <a href=""> tag and in that
context it should be HTML escaped, not URL escaped.

In addition to fixing a bug, this change cuts a dependency chain
from go/doc to net, clearing the way for use of cgo
(which imports go/doc) during the compilation of package net.
