Fixes <https://issues.guix.gnu.org/30116>.
Before this change, the presence of a NUL character on a line meant that
the (glibc) regexp engine used by Guile would either 1. stop scanning the
string or 2. crash with the error "string contains #\\nul character",
depending on the locale used.
This change works around this limitation by first replacing the NUL character
by an unused Unicode code point, doing the substitution, then reverting the
replacement.
* guix/build/utils.scm (unused-private-use-code-point)
(replace-char): New procedures.
(substitute): Make use of the above procedures to work around the NUL
character regexp engine limitation.
* tests/build-utils.scm: Add tests.

* guix/build/utils.scm (wrap-script): Use 'display' instead of passing a
non-literal string to 'format'.
xz compression is slow; using the multi-thread mode of xz can make it more
than 6 times faster, for example when compressing the large linux-libre
source.
* guix/build/utils.scm (%xz-parallel-args): New procedure.
* guix/packages.scm (patch-and-repack): Specify the required above xz
arguments by setting the XZ_DEFAULTS environment variable.
* guix/scripts/pack.scm (%compressors, bootstrap-xz): Modify the commands
Gexps so they do not need to be quoted. This allows lazily evaluating the
arguments on the builder's side. Specify the required xz arguments.
(self-contained-tarball): Do not quote the compressor command value.
(docker-image): Likewise.
* guix/utils.scm (decompressed-port, compressed-port)
(compressed-output-port): Specify the required above xz arguments.
This makes it so that delete-file-recursively honors its docstring, which says
it should "report but ignore errors".
Fixes <https://issues.guix.gnu.org/43366>.
* guix/build/utils.scm (warn-on-error): New syntax.
(delete-file-recursively): Use it to catch exceptions and print warning
messages.

* guix/build/utils.scm (setvbuf) [(and guile-2 (not guile-2.2))]: New
procedure.
(remove-store-references): Use the 2.2 'setvbuf' API style.
* guix/build/gnu-build-system.scm (gnu-build): Likewise.
* guix/build/python-build-system.scm (wrap): Only wrap executables that have
not already been wrapped.
* guix/build/utils.scm (wrapper?): New function.
When current-processor-count is used without (ice-9 threads) being used, Guile
complains with the following warning:
Import (ice-9 threads) to have access to `current-processor-count'.
* guix/build/utils.scm: Use (ice-9 threads).
* gnu/build/activation.scm (make-file-writable): Move this to ...
* guix/build/utils.scm (make-file-writable): ... here. Export it.
* guix/build/gnu-build-system.scm (strip): Use it.
This adds support for single-entry search paths.
Fixes <http://bugs.gnu.org/25422>.

* guix/search-paths.scm (<search-path-specification>)[separator]:
Document as string or #f.
(evaluate-search-paths): Add case for SEPARATOR as #f.
(environment-variable-definition): Handle SEPARATOR being #f.
* guix/build/utils.scm (list->search-path-as-string): Add case for
SEPARATOR as #f.

New field.
* guix/build/utils.scm (wrap-program)[wrapper-file-name]
[next-wrapper-number, wrapper-target]: Remove.
[wrapped-file, already-wrapped?]: New variables.
[last-line]: New procedure.
Use it to append to PROG when a wrapper already exists.

Adjust the list of files to delete.
* guix/build/utils.scm (strip-store-file-name): New procedure.
* guix/build/emacs-build-system.scm (store-directory->name-version):
Remove. Update callers to use 'strip-store-file-name'.
* gnu/packages/gcc.scm (make-libstdc++-doc)[arguments]: Use
'strip-store-file-name' instead of 'string-drop'.
Fixes <http://bugs.gnu.org/20081>.
Reported by Tomáš Čech <sleep_walker@suse.cz>.
* guix/build/utils.scm (find-files): Add #:stat parameter. Pass it as
last argument to 'file-system-fold'.
* guix/build/gremlin.scm (validate-needed-in-runpath)[runpath]:
Add (filter absolute-file-name? ...).
Emit a warning when RUNPATH file names that do not match
'store-file-name?'. Change format of error message to begin with file
name.
* guix/build/utils.scm (store-file-name?): New procedure.
* guix/build/utils.scm (file-name-predicate): New procedure.
(find-files): Rename second parameter to 'pred'. When 'pred' is not a
procedure, call 'file-name-predicate'. Use PRED instead of
'regexp-exec' in the leaf procedure.

(patch-shebang): Use it instead of 'read-char'.

* guix/build/utils.scm (wrap-program): Create scripts that use $0 (which is
