9b669efb38 Fail validation if we can't find shim and Secure Boot is enabled 
If grub is signed with a key that's in the trusted EFI keyring, an attacker
can point a boot entry at grub rather than at shim and grub will fail to
locate the shim verification protocol. This would then allow booting an
arbitrary kernel image. Fail validation if Secure Boot is enabled and we
can't find the shim protocol in order to prevent this.

9a67e1ac8e Use full initializer for initrd_ctx to avoid fatal warnings with older GCC 
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.

954fe77163 cleanup: grub_cpu_to_XXX_compile_time for constants 
This tries to catch all cases where grub_cpu_to_XXX was used for constant
expressions (including sizeof).

631a820038 Initialized initrd_ctx so we don't free a random pointer from the stack. 
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.
