Adds the Pool type and docs, and use it in fmt.
This is a temporary implementation, until Dmitry
makes it fast.

Uses the API proposal from Russ in http://goo.gl/cCKeb2 but
adds an optional New field, as used in fmt and elsewhere.
Almost all callers want that.

Previously the hash used when signing an X.509 certificate was fixed
and, for RSA, it was fixed to SHA1. Since Microsoft have announced the
deprecation of SHA1 in X.509 certificates, this change switches the
default to SHA256.

It also allows the hash function to be controlled by the caller by
setting the SignatureAlgorithm field of the template.

The set of certs fetched via exec'ing `security` is not quite identical
to the certs fetched via the cgo call. The cgo fetch includes
any trusted root certs that the user may have added; exec does not.
The exec fetch includes an Apple-specific root cert; the cgo fetch
does not. Other than that, they appear to be the same.

Unfortunately, os/exec depends on crypto/x509, via net/http. Break the
circular dependency by moving the exec tests to their own package.

This will not work in iOS; we'll cross that bridge when we get to it.

Don't make copies of keys while decoding, and don't use the
expensive strings.EqualFold when it's not necessary. Instead,
note in the existing field cache what algorithm to use to
check fold equality... most keys are just ASCII letters.

All packages now use the -pack option to the compiler.
For a pure Go package, that's enough.
For a package with additional C and assembly files, the extra
archive entries can be added directly (by concatenation)
instead of by invoking go tool pack.

These changes make it possible to rewrite cmd/pack in Go.

The -pack flag causes 5g, 6g, 8g to write a Go archive directly,
instead of requiring the use of 'go tool pack' to convert the .5/.6/.8
to .a format.

Writing directly avoids the copy and also avoids having the
export data stored twice in the archive (once in __.PKGDEF,
once in .5/.6/.8).

A separate CL will enable the use of this flag by cmd/go.

Other build systems that do not know about -pack will be unaffected.

The changes to cmd/ld handle a minor simplification to the format:
an unused section is removed.

Hash tables currently store an evacuated bit in the low bit
of the overflow pointer.  That's probably not sustainable in the
long term as GC wants correctly typed & aligned pointers.  It is
also a pain to move any of this code to Go in the current state.

This change moves the evacuated bit into the tophash entries.

Performance change is negligable.

gccgo has problems using reflect.Call with functions that take and
return structs with no members.  Prior to fixing that problem there, I
thought it sensible to add some tests of this situation.
