In master we have the function OPENSSL_clear_free(x,y), which immediately
returns if x == NULL. In <=1.0.2 this function does not exist so we have to
do:
OPENSSL_cleanse(x, y);
OPENSSL_free(x);

However, previously, OPENSSL_cleanse did not check that if x == NULL, so
the real equivalent check would have to be:
if (x != NULL)
    OPENSSL_cleanse(x, y);
OPENSSL_free(x);

It would be easy to get this wrong during cherry-picking to other branches
and therefore, for safety, it is best to just ensure OPENSSL_cleanse also
checks for NULL.

Rewrite EVP_DecodeUpdate.

In particular: reject extra trailing padding, and padding in the middle

Previously, the behaviour was ill-defined, and depended on the position
of the padding within the input.

In addition, this appears to fix a possible two-byte oob read.

Simplify encrypted premaster secret reading by using new methods in the
PACKET API.

Don't overwrite the packet buffer. RSA decrypt accepts truncated
ciphertext with leading zeroes omitted, so it's even possible that by
crafting a valid ciphertext with several leading zeroes, this could
cause a few bytes out-of-bounds write. The write is harmless because of
the size of the underlying message buffer, but nevertheless we shouldn't
write into the packet.

New ASN.1 macro ASN1_EMBED. This is the same as ASN1_SIMPLE except the
structure is not allocated: it is part of the parent. That is instead of

FOO *x;

it must be:

FOO x;

This reduces memory fragmentation and make it impossible to accidentally
set a mandatory field to NULL.

This currently only works for SEQUENCE and since it is equivalent to
ASN1_SIMPLE it cannot be tagged, OPTIONAL, SET OF or SEQUENCE OF.

This code does open-coded division on 64-bit quantities and thus when
building with GCC on 32-bit platforms will require functions such as
__umoddi3 and __udivdi3 from libgcc.

In constrained environments such as firmware, those functions may not
be available. So make it possible to compile out SCT support, which in
fact (in the case of UEFI) we don't need anyway.

we get a problem, because we were storing the temporary stderr file in
the current directory at all times (so while inside the 'indir', we
would attemp to store it in "foo.$$").

So, change our ways to always store that temporary file in the exact
same location, defined by the environment variable RESULT_D, or
failing that TEST_D, or failing that $TOP/test.

This provides support for building in the EDK II reference implementation
of UEFI. Most UEFI firmware in existence uses OpenSSL for implementing
the core cryptographic functionality needed for Secure Boot.

This has always previously been handled with external patches to OpenSSL
but we are now making a concerted effort to eliminate those.

In this mode, we don't actually use the OpenSSL makefiles; we process
the MINFO file generated by 'make files' and incorporate it into the
EDK2 build system.

Since EDK II builds for various targets with varying word size and we
need to have a single prepackaged configuration, we deliberately don't
hard-code the setting of SIXTY_FOUR_BIT vs. THIRTY_TWO_BIT in
opensslconf.h. We bypass that for OPENSSL_SYS_UEFI and allow EDK II
itself to set those, depending on the architecture.

For x86_64, EDK II sets SIXTY_FOUR_BIT and thus uses 'long long' for the
64-bit type, even when building with GCC where 'long' is also 64-bit. We
do this because the Microsoft toolchain has 32-bit 'long'.
