This patch allows to have bigger kernels. If the kernel grows, then it will
overwrite the initrd when it is extracted.

The verifiers framework changed the grub_file_open() interface, breaking all
non-x86 linux loaders. Add file types to the grub_file_open() calls to make
them build again.

The 32-bit arm efi port now shares the 64-bit linux loader, so delete
the now unused bits from the 32-bit linux loader.
This in turn leaves the grub-core/kern/arm/efi/misc.c unused, so
delete that too.

struct ... foo = { 0, } is valid initializer, but older GCC emits
warning which is fatal error due to -Werror=missing-field-initializer.
So simply use full initializer to avoid these errors. This was fixed
probably in GCC 4.7.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=36750
Currently, if "linux" fails, the "goto fail;" in grub_cmd_initrd sends us
into grub_initrd_close() without grub_initrd_init() being called, and thus
it never clears initrd_ctx->components. grub_initrd_close() then frees that
address, which is stale data from the stack. If the stack happens to have a
stale *address* there that matches a recent allocation, then you'll get a
double free later.
So initialize the memory up front.
