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).

HOWTO create an LLVM crosstool from x86_64/Linux to ARM/Linux
=============================================================

1. % llvm/utils/crosstool/create-snapshots.sh

   This will create llvm-[REV_L].tar.bz2 and llvm-gcc-4.2-[REV_G].tar.bz2,
   where:
     REV_L is the revision at which "llvm" was checked out, and
     REV_G is the revision at which "llvm-gcc-4.2" was checked out

   Note that REV_L might REV_G might not be the same revision.

2. Download CodeSourcery toolchain.  The exact location depends on your
   $CROSS_TARGET but the script will tell you what the location of the file is
   if you run it without having the file available.

   For example, if you're using $CROSS_TARGET == "arm-none-linux-gnueabi" then
   you need to download:

   http://www.codesourcery.com/sgpp/lite/arm/portal/package1787/public/arm-none-linux-gnueabi/arm-2007q3-51-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2

   NOTE: simply changing $CROSS_TARGET and modifying the URL accordingly will
   not work -- you'll need to go to http://www.codesourcery.com and find the
   correct file, as the release number in the file will also be different (e.g.,
   in the file above, the release number is "51").

3. You can override most values in the script without modifying it, e.g.
   $INSTALL_ROOT (if you want to install in directory other than /usr/local).

   Run the script as:

   % env INSTALL_ROOT=[dir to install in] \
         CODE_SOURCERY_PKG_PATH=[dir where you downloaded CodeSourcery tarball] \
         LLVM_PKG_PATH=[dir where you stored your LLVM and LLVM-GCC snapshots] \
         LLVM_SVN_REV=${REV_L} \
         LLVMGCC_SVN_REV=${REV_G} \
         build-install-linux.sh
