8e184454fd Fix Debian 8 and Leap_42.1 builds
Older versions of openssl 1.0.0 don't have X509_STORE_CTX_get0_store
so define that as well.

f065bb5705 tests: Fix up to work on arbitrary architectures
The current test infrastructure is tied to x86/amd64.  This means the
tests always fail on a non-x86 architecture (like aarch64).  Fix this
by generating the efi binary directly from C code and removing the
architectural restrictions in the Makefile.am.  One of the
consequences of this is that we no longer test ia32 on x86_64, but the
difficulty of detecting which architectures can support 32 bit
variants and generating them correctly from EFI c code is too great.

We also need to exclude tests involving objdump from aarch64 since its
bfd still doesn't have an efi_app_aarch64 target.

cbbafe244b tests/detach-remove.sh: fix for i386 pecoff size problems
pecoff for i386 can be too short, so it gets padded for an accurate
signature.  Make sure the size comparison takes this into account to
avoid spurious failures.

5b79ed2179 tests: fix signature resign/reattach test problems
The original tests to warn about overwriting signatures have never
worked after the multiple signature code was added (because we add a
new signature instead of overwriting the old one) update the tests to
check instead for the signature addition.

79d0c44afb Update OpenSSL API usage to support OpenSSL 1.1
Most structure definitions in OpenSSL are now opaque and we must call
the appropriate accessor functions to get information from them.
Not all the accessors are available in older versions, so define the
missing accessors as macros.

The X509_retrieve_match() function is no longer usable, as we cannot
initialise an X509_OBJECT ourselves.  Instead, iterate over the
certificate store and use X509_OBJECT_get_type and X509_cmp to
compare certificates.

e9626fefa1 Add OPENSSL_config(NULL) to each binary to load openssl.cnf
In the current framework for using engine based keys, the engine has
to be loaded and initialised as part of the default engines.  The only
way this can happen for the TPM engine is if it is named in a config
secion, so all the tools must read and act on the config file to be
able to use TPM based keys.

Note that for the ARM case, we are using IMAGE_FILE_MACHINE_THUMB (0x1c2)

592ec2188f Fix for multi-sign
The new Tianocore multi-sign code fails now for images signed with
sbsigntools.  The reason is that we don't actually align the signature table,
we just slap it straight after the binary data.  Unfortunately, the new
multi-signature code checks that our alignment offsets are correct and fails
the signature for this reason.  Fix by adding junk to the end of the image to
align the signature section.

274d4df0ff image: Allow variable sized data directories
The PE/COFF spec allows variable-sized data directories, which reduce
the size of the optional header. While GNU ld always produces
maximum-sized headers, the kernel's EFI_STUB code generates a smaller
header size, which causes the image parsing code to abort.

This change allows variable-sized optional headers, but checks for at
least enough of an optional header to contain a CERT_TABLE data
directory entry.

We also rename struct image's aouthdr to opthdr, as it contains more
than just the a.out fields.
