Leah Rowe d22f7f9633 update grub to 2.14 
This brings these extra changes:

* eaa3b8f0f Bump version to 2.15
* d38d6a1a9 Release 2.14
* 35bfd6c47 build: Add grub-core/tests/crypto_cipher_mode_vectors.h file to EXTRA_DIST
* ac042f3f5 configure: Print a more helpful error if autoconf-archive is not installed
* e37d02158 kern/ieee1275/openfw: Add a check for invalid partition number
* f94eae0f8 grub-mkimage: Do not generate empty SBAT metadata
* 1aa0dd0c0 configure: Defer check for -mcmodel=large until PIC/PIE checks are done
* ff1edd975 util/grub-mkimagexx: Stop generating unaligned appended signatures
* 51ebc6f67 tests: Add functional tests for ecb/cbc helpers
* caaf50b9a osdep/aros/hostdisk: Fix use-after-free bug during MsgPort deletion
* 18f08826f kern/efi/sb: Enable loading GRUB_FILE_TYPE_CRYPTODISK_ENCRYPTION_KEY and GRUB_FILE_TYPE_CRYPTODISK_DETACHED_HEADER

NOTE: This patch was reversed:

* ac042f3f5 configure: Print a more helpful error if autoconf-archive is not installed

Because it quite unhelpfully broke the build.

Subject: [PATCH 08/21] grub-core/bus/usb: Parse SuperSpeed companion
descriptors
Parse the SS_ENDPOINT_COMPANION descriptor, which is only present on USB 3.0
capable devices and xHCI controllers. Make the descendp an array of pointers
to the endpoint descriptor as it's no longer an continous array.
