3fafe2e888 internal/trace: support parsing of 1.5 traces
1. Parse out version from trace header.
2. Restore handling of 1.5 traces.
3. Restore optional symbolization of traces.
4. Add some canned 1.5 traces for regression testing
   (http benchmark trace, runtime/trace stress traces,
    plus one with broken timestamps).

53984e5be2 compress/flate: optimize huffman bit encoder
Part 1 of optimizing the deflater. This optimizes the bitwriter by:

* Removing allocations.
* Storing compound values for bit codes instead of 2 separate tables.
* Accumulate 48 bits between writes instead of 24.
* Inline bit flushing.

This also contains code that will be used in later CL's
(writeBlockDynamic, writeBlockHuff).

Tests for Huffman bit writer encoding regressions has been added.

fb880b8a03 cmd/newlink: delete
cmd/link is clearly the way forward.
The original rationale for cmd/newlink was that it would be a clean Go reimplementation.
But when push came to shove, cmd/link got converted from C instead,
and all the work on build modes and the like is in cmd/link now.
Cleaning up cmd/link is likely a much better plan.

This directory is something to delete from releases and the
testdata is something that breaks every time the .6 format changes.
Fix both problems by just deleting it outright.

2ae77376f7 all: link to https instead of http
The one in misc/makerelease/makerelease.go is particularly bad and
probably warrants rotating our keys.

I didn't update old weekly notes, and reverted some changes involving
test code for now, since we're late in the Go 1.5 freeze. Otherwise,
the rest are all auto-generated changes, and all manually reviewed.

Refactor main a bit to make it possible to run tests without an exec every time.
(Makes a huge difference in run time.)

Add a silver test. Not quite golden, since it looks for pieces rather than the
full output, and also includes tests for what should not appear.

003dccfac4 runtime, syscall: use the new get_random_bytes syscall for NaCl
The SecureRandom named service was removed in
https://codereview.chromium.org/550523002. And the new syscall
was introduced in https://codereview.chromium.org/537543003.

Accepting this will remove the support for older version of
sel_ldr. I've confirmed that both pepper_40 and current
pepper_canary have this syscall.

After this change, we need sel_ldr from pepper_39 or above to
work.

Fixes #9261
