grafts: Allow the replacement to have a different name.
* guix/build/graft.scm (replace-store-references): REPLACEMENT is now the full string, not just the hash. (rewrite-directory)[hash-mapping](valid-suffix?): Remove. (hash+suffix): Rename to... (hash+rest): ... this. Change to return the whole string as the second element of the list. Adjust 'match-lambda' expression accordingly; check whether the string length of the origin and replacement match. * tests/grafts.scm ("graft-derivation, grafted item uses a different name"): New test. * doc/guix.texi (Security Updates): Update sentence on the name/version restriction.

recursive: when an indirect dependency requires grafting, then grafting
``propagates'' up to the package that the user is installing.
-Currently, the graft and the package it replaces (@var{bash-fixed} and

+Currently, the length of the name and version of the graft and that of

+grafting works by patching files, including binary files, directly.
Other restrictions may apply: for instance, when adding a graft to a
package providing a shared library, the original shared library and its
replacement must have the same @code{SONAME} and be binary-compatible.
