Use mmap for the elf parser, reducing memory usage.

2025-10-30T07:13:03+00:00

The `file->bytevector' new procedure uses a memory mapped bytevector, so
parsing the ELF file reads only the sections needed, not the whole file.

* guix/scripts/pack.scm (wrapped-package): Use file->bytevector.
* guix/build/gremlin.scm (file-dynamic-info): Likewise.
(validate-needed-in-runpath): Likewise.
(strip-runpath): Likewise, and write to bytevector directly, avoiding a port.
(set-file-runpath): Likewise.
* tests/gremlin.scm (read-elf): Delete procedure.
("elf-dynamic-info-needed, executable"): Use file-dynamic-info.
("strip-runpath"): Likewise.
("elf-dynamic-info-soname"): Likewise.
 guix/build/debug-link.scm (set-debuglink-crc): Use file->bytevector.
* tests/debug-link.scm (read-elf): Delete procedure.
("elf-debuglink"): Rename to...
("elf-debuglink, no .gnu_debuglink section"): ... this.
("elf-debuglink", "set-debuglink-crc"): Use external store, and adjust to use
file->bytevector.
* gnu/packages/gnuzilla.scm (icecat-minimal) [#:phases]
{build-sandbox-whitelist}: Use `file-runpath'.
* gnu/packages/librewolf.scm (librewolf): Likewise.
