gnu: binutils-final: Make sure the output refers only to libc.

* gnu/packages/base.scm (binutils-final)[arguments]: Add
  #:allowed-references.

gnu: glibc-final: Make sure we hold just the right set of references.

* gnu/packages/base.scm (glibc-final): Wrap in
  'package-with-restricted-references'.

build-system/gnu: Add 'package-with-restricted-references'.

* guix/build-system/gnu.scm (package-with-restricted-references): New
  procedure.

gnu: glibc: Make sure the bootstrap libc is not in $CPATH.

This fixes a bug whereby the bootstrap-glibc headers could be picked up
when building libc.so, which could be noticed by the fact that the
.debug files contained references to bootstrap-glibc.

* gnu/packages/base.scm (glibc-final-with-bootstrap-bash)[arguments]:
  Add 'pre-configure' phase.
  [inputs]: Remove 'alist-delete' call.

gnu: Build the final Coreutils before Findutils.

This fixes a bug whereby Findutils' 'updatedb' script would retain a
reference to the bootstrap binaries ('sort', etc.)

* gnu/packages/base.scm (coreutils-final, %boot5-inputs): New variables.
  (%final-inputs): Use them.

gnu: gettext: Upgrade to 0.19.

* gnu/packages/gettext.scm (gnu-gettext): Upgrade to 0.19.
  [arguments] <phases>: Remove now unneeded 'link-expat' phase.  Patch
  lang-sh and msgfilter test scripts; patch msginit.c and project-id.
  Add #:make-flags.

Merge branch 'master' into core-updates

build-system/gnu: Add #:allowed-references.

* guix/build-system/gnu.scm (gnu-build): Add #:allowed-references.
  [canonicalize-reference]: New procedure.
  Pass #:allowed-references to 'build-expression->derivation'.
  (gnu-cross-build): Likewise.

derivations: 'build-expression->derivation' supports #:allowed-references.

* guix/derivations.scm (build-expression->derivation): Add
  #:allowed-references and pass it to 'derivation.
* doc/guix.texi (Derivations): Adjust accordingly.

services: Use a fixed GID for the build group and use that for the store.

This partly reverts commit 185f669 ("services: Make sure the store's
group is the build group.")

* gnu/services/base.scm (guix-service)[activate]: Remove 'chown' call.
  Add 'id' field to 'user-group' form.
* guix/build/install.scm (directives): Set the store's GID to 30000.

gnu: Add WakeLan.

* gnu/packages/admin.scm (wakelan): New variable.

gnu: openssl: Upgrade to 1.0.1h.

* gnu/packages/openssl.scm (openssl): Upgrade to 1.0.1h.  Remove
  patches, which are now upstream.
* gnu/packages/patches/openssl-extension-checking-fixes.patch: Remove.
* gnu/packages/patches/openssl-CVE-2010-5298.patch: Remove.
* gnu-system.am (dist_patch_DATA): Remove them.

gnu: bdb: Move documentation to "doc" output.

* gnu/packages/bdb.scm (bdb): Add 'outputs' field.  Adjust 'configure'
  phase to move documentation to the "doc" output.

gnu: Set proper source location for 'gcc-final'.

* gnu/packages/base.scm (gcc-final)[location]: New field.
  Reported by Andreas Enge <andreas@enge.fr>.

install: Add missing argv[0] in Info invocation.

* gnu/system/install.scm (log-to-info): Add "info" as second argument to
  'execl'.

activation: Only create groups that do not exist yet.

Before that the effect would be to re-create groups at each boot, and
thus remove any members of the groups.

* guix/build/activation.scm (activate-users+groups): Call 'add-group'
  only when (getgrname name) fails.

services: Make sure the store's group is the build group.

* gnu/services/base.scm (guix-service)[activate]: New variable.  Add
  'chown' call for (%store-prefix).  Set the 'activate' field to
  ACTIVATE.
* guix/build/install.scm (directives): Add comment about STORE's group.

services: Add the build group to the supplementary groups of build users.

* gnu/services/base.scm (guix-build-accounts): Add
  'supplementary-groups' field.

tests: Skip tests that would hit the shebang length limitation.

* tests/gexp.scm (shebang): New variable.
  Skip "gexp->script" when SHEBANG is longer than 127 chars.
* guix/gexp.scm (gexp->script): Add comment on the issue.

system: Tell module-init-tools where to look for modules.

* gnu/packages/linux.scm (module-init-tools)[source](patches): New
  field.
