packages: Introduce <content-hash> and use it in <origin>.

Browse source 
* guix/packages.scm (<content-hash>): New record type.
(define-content-hash-constructor, build-content-hash)
(content-hash): New macros.
(print-content-hash): New procedure.
(<origin>): Rename constructor to '%origin'.
[sha256]: Remove field.
[hash]: New field.  Adjust users.
(origin-compatibility-helper, origin): New macros.
(origin-sha256): New deprecated procedure.
(origin->derivation): Adjust accordingly.
* tests/packages.scm ("package-source-derivation, origin, sha512"): New
test.
* guix/tests.scm: Hide (gcrypt hash) 'sha256' for proper syntax
matching.
* tests/challenge.scm: Add #:prefix for (gcrypt hash) and adjust users.
* tests/derivations.scm: Likewise.
* tests/store.scm: Likewise.
* tests/graph.scm ("bag DAG, including origins"): Provide 'sha256' field
with the right length.
* gnu/packages/aspell.scm (aspell-dictionary)
(aspell-dict-ca, aspell-dict-it): Use 'hash' and 'content-hash' for
proper syntax matching.
* gnu/packages/bash.scm (bash-patch): Rename 'sha256' to 'sha256-bv'.
* gnu/packages/bootstrap.scm (bootstrap-executable): Rename 'sha256' to 'bv'.
* gnu/packages/readline.scm (readline-patch): Likewise.
* gnu/packages/virtualization.scm (qemu-patch): Rename 'sha256' to
'sha256-bv'.
* guix/import/utils.scm: Hide (gcrypt hash) 'sha256'.

A bytevector containing the SHA-256 hash of the source. Typically the
@code{base32} form is used here to generate the bytevector from a
base-32 string.
A bytevector containing the SHA-256 hash of the source. This is
equivalent to providing a @code{content-hash} SHA256 object in the
@code{hash} field described below.
@item @code{hash}
The @code{content-hash} object of the source---see below for how to use
@code{content-hash}.

@deftp {Data Type} content-hash @var{value} [@var{algorithm}]
Construct a content hash object for the given @var{algorithm}, and with
@var{value} as its hash value. When @var{algorithm} is omitted, assume
it is @code{sha256}.
@var{value} can be a literal string, in which case it is base32-decoded,
or it can be a bytevector.
The following forms are all equivalent:
@lisp
(content-hash "05zxkyz9bv3j9h0xyid1rhvh3klhsmrpkf3bcs6frvlgyr2gwilj")
(content-hash "05zxkyz9bv3j9h0xyid1rhvh3klhsmrpkf3bcs6frvlgyr2gwilj"
sha256)
(content-hash (base32
"05zxkyz9bv3j9h0xyid1rhvh3klhsmrpkf3bcs6frvlgyr2gwilj"))
(content-hash (base64 "kkb+RPaP7uyMZmu4eXPVkM4BN8yhRd8BTHLslb6f/Rc=")
sha256)
@end lisp
Technically, @code{content-hash} is currently implemented as a macro.
It performs sanity checks at macro-expansion time, when possible, such
as ensuring that @var{value} has the right size for @var{algorithm}.
