Adam Langley 5626bd9e38 crypto/tls: load a chain of certificates from a file.
Many recently issued certificates are chained: there's one or more
intermediate certificates between the host certificate and the root CA
certificate. This change causes the code to load any number of
certificates from the certificate file. This matches the behaviour of
common webservers, and the output of OpenSSL's command line tools.

OpenPGP changed its OCFB mode for more modern packets (for example, the

Adam Langley e308d55973 crypto: add package.
The crypto package is added as a common place to store identifiers for
hash functions. At the moment, the rsa package has an enumeration of
hash functions and knowledge of their digest lengths. This is an
unfortunate coupling and other high level crypto packages tend to need
to duplicate this enumeration and knowledge (i.e. openpgp).

crypto pulls this code out into a common location.

It would also make sense to add similar support for ciphers to crypto,
but the problem there isn't as acute that isn't done in this change.

Adam Langley 5aeacadc5a crypto/openpgp: add error and armor
error is needed by all the OpenPGP packages as they return a shared
family of error types.

armor implements OpenPGP armoring. It's very like PEM except:
  a) it includes a CRC24 checksum
  b) PEM values are small (a few KB) and so encoding/pem assumes that
     they fit in memory. Armored data can be very large and so this
     package presents a streaming interface.

Adam Langley eedf5c4529 crypto/tls: support CBC ciphers
This is largely based on ality's CL 2747042.

crypto/rc4: API break in order to conform to crypto/cipher's
Stream interface

cipher/cipher: promote to the default build

Since CBC differs between TLS 1.0 and 1.1, we downgrade and
support only 1.0 at the current time. 1.0 is what most of the
world uses.

Given this CL, it would be trival to add support for AES 256,
SHA 256 etc, but I haven't in order to keep the change smaller.

Adam Langley 836529a63c crypto/tls: use pool building for certificate checking
Previously we checked the certificate chain from the leaf
upwards and expected to jump from the last cert in the chain to
a root certificate.

Although technically correct, there are a number of sites with
problems including out-of-order certs, superfluous certs and
missing certs.

The last of these requires AIA chasing, which is a lot of
complexity. However, we can address the more common cases by
using a pool building algorithm, as browsers do.

We build a pool of root certificates and a pool from the
server's chain. We then try to build a path to a root
certificate, using either of these pools.

This differs from the behaviour of, say, Firefox in that Firefox
will accumulate intermedite certificate in a persistent pool in
the hope that it can use them to fill in gaps in future chains.

We don't do that because it leads to confusing errors which only
occur based on the order to sites visited.

This change also enabled SNI for tls.Dial so that sites will return
the correct certificate chain.

Previously all the functions took two arguments: src, dst. This is the
reverse of the usual Go style and worth changing sooner rather than

Rob Pike 12da5a90e0 log: new interface
New logging interface simplifies and generalizes.

1) Loggers now have only one output.
2) log.Stdout, Stderr, Crash and friends are gone.
	Logging is now always to standard error by default.
3) log.Panic* replaces log.Crash*.
4) Exiting and panicking are not part of the logger's state; instead
	the functions Exit* and Panic* simply call Exit or panic after
	printing.
5) There is now one 'standard logger'.  Instead of calling Stderr,
	use Print etc.  There are now triples, by analogy with fmt:
		Print, Println, Printf
	What was log.Stderr is now best represented by log.Println,
	since there are now separate Print and Println functions
	(and methods).
6) New functions SetOutput, SetFlags, and SetPrefix allow global
	editing of the standard logger's properties.   This is new
	functionality. For instance, one can call
		log.SetFlags(log.Lshortfile|log.Ltime|log.Lmicroseconds)
	to get all logging output to show file name, line number, and
	time stamp.

In short, for most purposes
	log.Stderr -> log.Println or log.Print
	log.Stderrf -> log.Printf
	log.Crash -> log.Panicln or log.Panic
	log.Crashf -> log.Panicf
	log.Exit -> log.Exitln or log.Exit
	log.Exitf -> log.Exitf (no change)

This has a slight breakage: since loggers now write only to one
output, existing calls to log.New() need to delete the second argument.
Also, custom loggers with exit or panic properties will need to be
reworked.

All package code updated to new interface.

The test has been reworked somewhat.

The old interface will be removed after the new release.
For now, its elements are marked 'deprecated' in their comments.

Fixes #1184.
