Introduce embedded mode conditional compilation
When running on embedded targets software cryptography is often not
available due to inadequate toolchain capabilities and limited
hardware resources.
Invoking make with EMBEDDED_MODE=1 ROOTDIR=1 will stub out
cryptographic functions and will provide another -I preprocessor
option to allow to pull in alternative .h files not available from the
toolchain.
NV Ram buffer size provisionally is being reduced to 8K. In final
embedded implementation NVRam might be held in flash, in which case
the required memory buffer could limited to one flash block size.
Some big data objects not used in the code are also being compiled out
when building for embedded mode of operation.
BUG=chrome-os-partner:43025
TEST=with the rest of the changes in place the code compiles with the
EC, and TPM startup sequence gets invoked.

Add ExecCommand_fp.h.
Add file ExecCommand_fp.h. Needed for inclusion in TPM2.0 simulator.
TPMCmdp.c includes ExecCommand_fp.h implying that it should exist.
Added package name HandleProcess_fp.h header guard.
TEST=$ sudo emerge tpm2
builds libtpm2.a
BUG=None

Remove instances of calling marshal functions with NULL pointer.
In the code scraped from the TCG TPM2.0 Library specification, there
are several instances where the intent is to marshal data into a buffer,
but NULL pointer is passed in as size.
Part 4 section 4.2.3.1 states: "If size is a NULL pointer, then no
data is marshaled and the routine will compute the size of the memory
required to marshal the indicated type."
Implying these usages are bugs. This CL removes all instances of passing
in NULL as size to a Marshal function when the intent is to marshal data.
TEST=$ sudo emerge tpm2
builds libtpm2.a. Currently this is the only test we have for the
scraped code.

Initial commit to seed TPM2.0 source code directory
LICENSE file text copied from TCG library specification. README
describes the procedure used to extract source code from parts 3 and 4
of the specification.
The python scripts and part{34}.txt files will be removed in the
following commits.
