Reported by Mark H Weaver <mhw@netris.org>.
* gnu/packages.scm (find-packages-by-name): Use 'version-prefix?'
instead of 'string-prefix?'.
This reduces the closure of (guix discovery) from 28 to 8 modules.
* guix/discovery.scm (scheme-files): Use 'format' instead of 'warning'.
(scheme-modules): Add #:warn parameter. Use it instead of
'warn-about-load-error'.

'(compose list specification->package+output)' to using
'specifications->manifest'.

* tests/guix-build.sh: Remove test for "time-1.7" syntax.

This provides a way to mark a package as superseded by another one.
Upgrades replace superseded packages with their replacement.
* guix/packages.scm (package-superseded, deprecated-package): New
procedures.
* gnu/packages.scm (%find-package): Check for 'package-superseded'.
* guix/scripts/package.scm (transaction-upgrade-entry)[supersede]: New
procedure. Call it when 'package-superseded' is true.

("transaction-upgrade-entry, superseded package"): New tests.
Fixes a thinko introduced in 1b846da8c3
that would lead to a backtrace when looking for an unknown package.
* gnu/packages.scm (%find-package): Correct logic when checking for
FALLBACK?.
Fixes a typo introduced in 1b846da8c3 that
would lead to a backtrace when using the deprecated syntax.
* gnu/packages.scm (%find-package): Turn the first argument to
'call-with-values' into a thunk. Use #:select instead of '@' to select
the right 'package-name->name+version' procedure.
This provides the ability to use numbers in package names.
Fixes <http://bugs.gnu.org/19219>.
* guix/utils.scm (package-name->name+version): New procedure.

These procedures are now redundant with those in (guix graph) and are no
longer used since commit a51cbecb.
