738f6f09b3 Rework linux16 command
We want a single buffer that contains the entire kernel image in order to
perform a TPM measurement. Allocate one and copy the entire kernel int it
before pulling out the individual blocks later on.

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.
