4de15a5cda compress/flate: optimize history-copy decoding. 
The forwardCopy function could be re-written in asm, and the copyHuff
method could probably be rolled into huffmanBlock and copyHist, but
I'm leaving those changes for future CLs.

f72c828c67 net: consolidate common socket functions 
In resolving 3507, the fix had to be applied individually to
the four *Conn types, tcp, udp, rawip and unix, due to the
duplicate code in each Conn type.

This CL consolidates the common net.Conn methods that all four
*Conn types implement into a base conn type.

Pros:
* The fix for 3507 would have only needed to be applied to one
method. Further improvements, such as possibly removing the
c.fd != nil check in c.ok(), would benefit from this CL.
* Nearly 300 lines removed from the net package.
* The public interface and documentation are not changed.
* I think this is an excellent example of the power of embedding.

Cons:
* The net package is already distributed over many files, this
CL adds another place to look.
* The fix for 3507 was a total of 16 lines changed, this follow
up CL could be considered to be an overreaction as new Conn types
are unlikely to be added in the near future.

d09943aeaf cmd/go: new tag selection logic 
The new logic is "use go1 if it's there, otherwise no tag."
Nothing needs to say "I require go1.0.1", and I want to
preserve some flexibility in defining what tags mean.

Right now (before go1.0.1) there is only one possible tag,
"go1", and I'd like to keep it that way.

5491623406 syscall: fix a number of exec bugs on Plan 9 
1. Readdirnames was erroneously returning an
   empty slice on every invocation.

2. The logic for determining which files to
   close before exec was incorrect.  If the
   set of files to be kept open (provided by
   the caller) did not include the files
   opened at startup, those files would be
   accidentally closed.

I also cleaned up readdupdevice while I was
in the vicinity.

689d5b9163 runtime: use __tfork() syscall on openbsd 
Switch from using the rfork() syscall on OpenBSD, to the __tfork()
syscall.  The __tfork() syscall is the preferred way of creating
system threads and the rfork() syscall has recently been removed.

Note: this will break compatibility with OpenBSD releases prior to 5.1.

fdce27f7b8 exp/locale/collate: Added Builder type for generating a complete 
collation table. At this moment, it only implements the generation of
a root table.

52f0afe0db exp/locale/collate: Added skeleton for the higher-level types to provide 
context for change lists of lower-level types. The public APIs are defined
in builder.go and collate.go. Type table is the glue between the lower and
higher level code and might be a good starting point for understanding the
collation code.

bcf48c7971 exp/locale/collate: added trie for associating colElems to runes. 
The trie code looks a lot like the trie in exp/norm. It uses different
types, however.  Also, there is only a lookup for []byte and the unsafe
lookup methods have been dropped, as well as sparse mode.
There is now a method for generating a trie. To output Go code, one now needs
to first generate a trie and then call print() on it.

e456d015fb exp/locale/collate: implementation of trie that is used for detecting contractions. 
(See http://www.unicode.org/reports/tr10/#Contractions.)  Each rune that is at the
start of any contraction is associated a trie. This trie, in turn, may be shared
by other runes that have the same set of suffixes.
