vasilito cb424d7448 build: static patch-sanity linter (shift-left the malformed-patch class)
verify-patch-sanity.py validates every active recipe .patch has internally-
consistent hunk line counts — catching the 'malformed patch at line N' failure
at commit/CI/preflight time instead of hours into a cook. This cycle hit that
class three times (qtwaylandscanner, sddm, xwayland), each only discovered when
cookbook tried to apply the patch.

Running it across the repo found 29 latent malformed patches (validated against
GNU patch: e.g. relibc/P3-sysv-ipc reproduces 'malformed patch at line 22').
They were harmless only because they sit in vendored recipes (baked, not re-
applied) — but would fail on any version-bump re-derivation. --fix recounts the
hunk headers (body untouched) and repaired all 29.

Wired into build-preflight.sh (Phase 1.0D) and redbear-ci.yml, with a unit test
(test-patch-sanity.sh). Skips archived/legacy trees and unvalidatable formats
(empty placeholders, bare-@@ git hunks).

llvm-readelf - GNU-style LLVM Object Reader
===========================================
.. program:: llvm-readelf
SYNOPSIS
--------
:program:`llvm-readelf` [*options*] [*input...*]
DESCRIPTION
-----------
The :program:`llvm-readelf` tool displays low-level format-specific information
about one or more object files.
If ``input`` is "``-``", :program:`llvm-readelf` reads from standard
input. Otherwise, it will read from the specified ``filenames``.
OPTIONS
-------
.. option:: --all, -a
Equivalent to specifying all the main display options relevant to the file
format.
.. option:: --addrsig
Display the address-significance table.
.. option:: --arch-specific, -A
Display architecture-specific information, e.g. the ARM attributes section on ARM.
.. option:: --bb-addr-map
Display the contents of the basic block address map section(s), which contain the
address of each function, along with the relative offset of each basic block.
.. option:: --decompress, -z
Dump decompressed section content when used with ``-x`` or ``-p``.
If the section(s) are not compressed, they are displayed as is.
.. option:: --demangle, -C
Display demangled symbol names in the output.
.. option:: --dependent-libraries
Display the dependent libraries section.
.. option:: --dyn-relocations
Display the dynamic relocation entries.
.. option:: --dyn-symbols, --dyn-syms
Display the dynamic symbol table.
.. option:: --dynamic-table, --dynamic, -d
Display the dynamic table.
.. option:: --cg-profile
Display the callgraph profile section.
.. option:: --histogram, -I
Display a bucket list histogram for dynamic symbol hash tables.
.. option:: --elf-linker-options
Display the linker options section.
.. option:: --elf-output-style=<value>
Format ELF information in the specified style. Valid options are ``LLVM``,
``GNU``, and ``JSON``. ``LLVM`` output is an expanded and structured format.
``GNU`` (the default) output mimics the equivalent GNU :program:`readelf`
output. ``JSON`` is JSON formatted output intended for machine consumption.
.. option:: --extra-sym-info
Display extra information (section name) when showing symbols.
.. option:: --section-groups, -g
Display section groups.
.. option:: --expand-relocs
When used with :option:`--relocations`, display each relocation in an expanded
multi-line format.
.. option:: --file-header, -h
Display file headers.
.. option:: --gnu-hash-table
Display the GNU hash table for dynamic symbols.
.. option:: --hash-symbols
Display the expanded hash table with dynamic symbol data.
.. option:: --hash-table
Display the hash table for dynamic symbols.
.. option:: --headers, -e
Equivalent to setting: :option:`--file-header`, :option:`--program-headers`,
and :option:`--sections`.
.. option:: --help
Display a summary of command line options.
.. option:: --hex-dump=<section[,section,...]>, -x
Display the specified section(s) as hexadecimal bytes. ``section`` may be a
section index or section name.
.. option:: --memtag
Display information about memory tagging present in the binary. This includes
various memtag-specific dynamic entries, decoded global descriptor sections,
and decoded Android-specific ELF notes.
.. option:: --needed-libs
Display the needed libraries.
.. option:: --no-demangle
Do not display demangled symbol names in the output. On by default.
.. option:: --notes, -n
Display all notes.
.. option:: --pretty-print
When used with :option:`--elf-output-style`, JSON output will be formatted in
a more readable format.
.. option:: --program-headers, --segments, -l
Display the program headers.
.. option:: --relocations, --relocs, -r
Display the relocation entries in the file.
.. option:: --sections, --section-headers, -S
Display all sections.
.. option:: --section-data
When used with :option:`--sections`, display section data for each section
shown. This option has no effect for GNU style output.
.. option:: --section-details, -t
Display all section details. Used as an alternative to :option:`--sections`.
.. option:: --section-mapping
Display the section to segment mapping.
.. option:: --section-relocations
When used with :option:`--sections`, display relocations for each section
shown. This option has no effect for GNU style output.
.. option:: --section-symbols
When used with :option:`--sections`, display symbols for each section shown.
This option has no effect for GNU style output.
.. option:: --stackmap
Display contents of the stackmap section.
.. option:: --stack-sizes
Display the contents of the stack sizes section(s), i.e. pairs of function
names and the size of their stack frames. Currently only implemented for GNU
style output.
.. option:: --string-dump=<section[,section,...]>, -p
Display the specified section(s) as a list of strings. ``section`` may be a
section index or section name.
.. option:: --symbols, --syms, -s
Display the symbol table. Also display the dynamic symbol table when using GNU output style for ELF.
.. option:: --unwind, -u
Display unwind information.
.. option:: --version
Display the version of the :program:`llvm-readelf` executable.
.. option:: --version-info, -V
Display version sections.
.. option:: --wide, -W
Ignored for GNU readelf compatibility. The output is already similar to when using -W with GNU readelf.
.. option:: @<FILE>
Read command-line options from response file `<FILE>`.
EXIT STATUS
-----------
:program:`llvm-readelf` returns 0 under normal operation. It returns a non-zero
exit code if there were any errors.
