This moves the parts of pe.c that *don't* depend on Cryptlib into
pe-relocate.c, so we can write test cases for them without having to
make a second openssl build without EFI support.

In the future we will want to examine binaries without wanting to
execute them. Create verify_image based off existing handle_image
code.

This implements SBAT verification via the shim_lock protocol
by moving verification inside the existing verify_buffer()
function that is shared by both shim_verify() and handle_image().
The .sbat section is optional for code verified via the shim_lock
protocol, unlike for code that is verified and executed directly
by shim. For executables that don't have a .sbat section,
verification is skipped when using the protocol.
A vendor can enforce SBAT verification for code verified via the
shim_lock protocol by revoking all pre-SBAT binaries via a dbx
update or by using vendor_dbx and then only signing binaries that
have a .sbat section from that point.

Copying the value of datasize_in to two further variables and then using
all three randomly in the code makes it hard to read.
datasize_in is never changed in generate_hash() so we can do with this
parameter alone. Rename it to datasize.

This is needed for shim to verify itself when booting, to make sure that
shim binaries can't be executed anymore after been revoked by SBAT.

I renamed PeImage.h to pe.h when I de-capitalized them, but this turns
out to be a bad idea because we already have a pe.h on the SBAT branch.
Woops.
This moves it to peimage.h

clang-format doesn't allow you to specify an include sort order, and
just assumes asciibetical is a pretty good order, which doesn't work as
well as you would hope.
This makes them all lower case so they don't need to be re-sorted.
I also went through and checked that we're using quoted local includes
at all the appropriate places.
