This is a replacement for pending CL 2219042. It only contains
the raw suffixarray functionality with two methods:
- New create a new index from some data
- Lookup lookup occurences of a bytes slice in the data
Any other functionality (dealing with multiple data sets and
the corresponding position lists) is generic and doesn't have
to be part of this package.
Known performance bug: This implementation works fine for data sets
up to several megabytes as long as it doesn't contain very long
contiguous sequences of equal bytes. For instance, index creation for
all .go files under GOROOT (250KLOCs, approx. 9MB) takes ~50s on
2.66 GHz Intel Xeon as long as test/fixedbugs/257.go is excluded.
With that file, index creation times takes several days. 257.go contains
a string of 1M smiley faces.
There are more sophisticated suffixarray creation algorithms which
can handle very long common prefixes. The implementation can be
updated w/o the need to change the interface.

The key/value format of X.500 names means that it's possible to encode
a name with multiple values for, say, organisation. RFC5280
doesn't seem to consider this, but there are Verisign root
certificates which do this and, in order to find the correct
root certificate in some cases, we need to handle it.
Also, CA certificates should set the CA flag and we now check
this. After looking at the other X.509 extensions it appears
that they are universally ignored/bit rotted away so we ignore
them.

Also add exporter.Drain() to wait for completion.
This makes it possible for an Exporter to fire off a message
and wait (by calling Drain) for the message to be received,
even if a client has yet to call to retrieve it.
Once this design is settled, I'll do the same for import send.
Testing strategies welcome. I have some working stand-alone
tests.

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.

- 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

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.
