Edk2 renamed OpenSslSupport.h, so we have to follow the change.
Also merge some changes from edk2 CrtLibSupport.h

The commit 03b9f800 introduces an issue in case the gap between
SumOfBytesHashed and context->SecDir->VirtualAddress exists.
This would be a typo because a formal PE image always meet
SumOfBytesHashed + hashsize == context->SecDir->VirtualAddress either
the gap exists or not.

Update to edk2 commit 6e4489d8129d233ef0fe85eeb6eebfecafe9ea6e
(CryptoPkg: Refine type cast for pointer subtraction)
Also replaced CryptAes.c, CryptArc4.c, CryptTdes.c, CryptMd4.c,
CryptHmacMd5.c, and CryptHmacSha1.c with the Null version since
we don't really need those functions.

Under a strict memory protection policy, UEFI may give out EfiLoaderData
memory with the XN attribute set. So use EfiLoaderCode explicitly.
At the same time, use a page based allocation rather than a pool
allocation, which is more appropriate when loading PE/COFF images.

This makes it so two builds of the same .deb on different hosts won't
have wildly different file offsets.

Previously we were returning EFI_ACCESS_DENIED at some places and
EFI_SECURITY_VIOLATION at others. When we're checking whether to run
MokManager, we're checking EFI_SECURITY_VIOLATION, which is more or less
analogous with what the spec says StartImage() returns. So we should
always have that as the return code.
I believe this will fix github issue #44.

EFI TrEE Protocol uses the same protocol GUID as EFI TCG2 protocol, and
defines the capability structure version 1.0. Hence, the structure and
name are all align the EFI TrEE Protocol.

Some machines have already embedded MokSBStateRT varaible with
EFI_VARIABLE_NON_VOLATILE attribute, and some users might disable shim
vailidation manually by creating MokSBStateRT. It causes mirroring MokSBState
fail because the variable cannot be set with different attribute again, and gets
error massage every time when booting.
Fix it with checking the MokSBStateRT existence and deleting it before
mirroring it.

Currently generate_hash() attempts to include any trailing data at the
end of the binary in the resulting digest, but it won't include such
data if the size computed is wrong because context->SecDir->Size is
invalid. In this case the return code is EFI_SUCCESS, and the hash will
match any a binary as if the Attribute Certificate Table and anything
after it are missing. This is wrong.

Although the prototype of memset() is already defined in OpenSslSupport.h,
the function was never implemented. It was fine since a macro was
designed to replace all memset() with SetMem() after including
OpenSslSupport.h. However, since openssl 1.0.2j, a new function pointer
in crypto/mem_clr.c requires the "real" memset() or the program would
crash due to the NULL function pointer access. This commit implements
memset() (just a wrapper of SetMem()) to avoid the potential crash.

Certain AMI BIOS (Intel NUC5i3MYBE BIOS version 0037) may make the strict
check on the last 3 arguments passed to get_event_log() and don't expect
NULL pointers are passed. In order to work around this failure
(EFI_INVALID_PARAMETER), pass them even though we really don't use it.

* Update Standards-Version.
* Embed the newly-minted Debian CA certificate.
* Vendorize debian/rules so that the same package can be used in both
Debian and Ubuntu without modification.
* Fix debian/copyright to match the spec (last match wins, not first)
* Fix shim.efi to not be executable.
* Add watchfile.
* Support parallel builds, because eh why not
* Update Vcs-Bzr.
According to TCG EFI Protocol Specification for TPM 2.0 family,
all events generated after the invocation of EFI_TCG2_GET_EVENT_LOG
shall be stored in an instance of an EFI_CONFIGURATION_TABLE aka
EFI TCG 2.0 final events table. Hence, it is necessary to trigger the
internal switch through calling get_event_log() in order to allow
to retrieve the logs from OS runtime.

For starters; don't allow the "module signing" OID; which ought to
only ever be used for signing kernel modules, not signing EFI binaries.

Try to append the MOK/MOKX list first and then fallback to the normal

We got the bug report about the usage of APPEND_WRITE that may cause the
failure when writing a variable in Lenovo machines. Although
EFI_VARIABLE_APPEND_WRITE already exists in the UEFI spec for years,
unfortunately, some vendors just ignore it and never implement the
attribute. This commit removes the usage of EFI_VARIABLE_APPEND_WRITE to
make MokManager work on those machines.
