- Unified bounary conditions for NFC and NFD and removed some indirections.
This enforces boundaries at the character level, which is typically what
the user expects. (NFD allows a boundary between 'a' and '`', for example,
which may give unexpected results for collation. The current implementation
is already stricter than the standard, so nothing much changes. This change
just formalizes it.
- Moved methods of qcflags to runeInfo.
- Swapped YesC and YesMaybe bits in qcFlags. This is to aid future changes.
- runeInfo return values use named fields in preperation for struct change.
- Replaced some left-over uint32s with rune.

work in progress, and we are not ready to freeze its API for Go 1.
Package html still exists, containing just two functions: EscapeString
and UnescapeString.
Both the packages at exp/html and html are "package html". The former
is a superset of the latter.
At some point in the future, the exp/html code will move back into

Remove NewMD5, NewSHA1 and NewSHA256 in favor of using New and

Previously, a timeout (in int64 nanoseconds) applied to a granularity
even smaller than one operation: a 100 byte read with a 1 second timeout
could take 100 seconds, if the bytes all arrived on the network 1 second
apart. This was confusing.
Rather than making the timeout granularity be per-Read/Write,
this CL makes callers set an absolute deadline (in time.Time)
after which operations will fail. This makes it possible to
set deadlines at higher levels, without knowing exactly how
many read/write operations will happen in e.g. reading an HTTP
request.

First was, apart from adding tests, a single line of code (to add the
constructor function). Adding SHA512-based hashing to crypto/hmac
required minor rework of the package because of a previously hardcoded
block-size in it's implementation. Instead of using a hash.Hash
generator function the constructor function now uses a crypto.Hash
type, which was extended to expose information about block size.
The only standard library package impacted by the change is
crypto/tls, for which the fix is included in this patch. It might be
useful to extend gofix to include this API change too.

This CL fixes two issues sending data to the remote peer.
The first bug occurs when the size of the buffer passed to
Write is larger than the current window, in this case, w.rwin
can become negative.
The second issue is more problematic than the first as the
amount of data passed to writePacket was not limited to w.rwin.
In this case the remote peer could silently drop the additional
data, or drop the connection.

I added the clientChan's msg channel to the list of channels that are closed in mainloop when the server sends a channelCloseMsg.
I added an ExitError type that wraps a Waitmsg similar to that of os/exec. I fill ExitStatus with the data returned in the 'exit-status' channel message and Msg with the data returned in the 'exit-signal' channel message.
Instead of having Wait() return on the first 'exit-status'/'exit-signal' I have it return an ExitError containing the status and signal when the clientChan's msg channel is closed.
I added two tests cases to session_test.go that test for exit status 0 (in which case Wait() returns nil) and exit status 1 (in which case Wait() returns an ExitError with ExitStatus 1)

This is part one of a small set of CL's that aim to resolve
the outstanding TODOs relating to channel close and blocking
behavior.
Firstly, the hairy handling of assigning the peersId is now
done in one place. The cost of this change is the slightly
paradoxical construction of the partially created clientChan.
Secondly, by creating clientChan.stdin/out/err when the channel
is opened, the creation of consumers like tcpchan and Session
is simplified; they just have to wire themselves up to the
relevant readers/writers.

The SSH spec allows for the server to send a banner message to the client at any point during the authentication process. Currently the ssh client auth types all assume that the first response from the server after issuing a userAuthRequestMsg will be one of a couple of possible authentication success/failure messages. This means that client authentication breaks if the ssh server being connected to has a banner message configured.
This changeset refactors the noneAuth, passwordAuth and publickeyAuth types' auth() function and allows for msgUserAuthBanner during authentication.

Exec() has been renamed to Run() in keeping with the os/exec API.
Added func (*Session) Start(cmd string) which starts a remote process but unlike Run() doesn't wait for it to finish before returning.
Run() has been refactored to use Start internally. Its really just a refactoring, no new code but some extra functionality was won.
Also added func (*Session) Signal(sig signal) which sends a UNIX signal to a remote process. This is espcially useful in conjunction with Start() as the two allow you to start a remote process, monitor its stdout/stderr, and send it a TERM/HUP/etc signal when you want it to close.

According to http://www.ietf.org/rfc/rfc4254.txt most channel messages contain the channel id of the recipient channel, not the sender id. This allows the recipient connection multiplexer to route the message to the correct channel.
This changeset fixes several messages that incorrectly send the local channel id instead of the remote channel's id.
While sessions were being created and closed in sequence channels in the channel pool were freed and reused on the server side of the connection at the same rate as was done on the client, so the channel local and remote channel ids always corresponded. As soon as I had concurrent sessions on the same clientConn the server started to complain of 'uknown channel id N' where N is the local channel id, which is actually paired with server channel id K.

This CL inverts the direction of the Stdin/out/err members of the
Session struct so they reflect the API of the exec.Cmd. In doing so
it borrows heavily from the exec package.
Additionally Shell now returns immediately, wait for completion using

command is complete.
