pinweaver: Build for Ti50

Add Makefile, Cargo.toml, build.rs, etc to enable building the
Pinweaver library for Ti50.
Add bindings.rs (generated using bindgen) to allow the library to be
called from Rust.

BUG=b:165024054
TEST=pinweaver_client selftest

Common PinWeaver Code

This directory contains reference PinWeaver code that can be used across implementation platforms.

It consists of:

  • PinWeaver reference code:
    • pinweaver.h - PinWeaver embedded API definition
    • pinweaver.c - implementation
    • pinweaver_eal.h - API for Environment Abstraction Layer (EAL) used by PinWeaver
      • note that some types used in this API are platform-specific and are defined in eal/**/pinweaver_eal_types.h
    • pinweaver_types.h - header that is shared by PinWeaver implementation and PinWeaver clients that call it through platform-specific interface.
  • Environment Abstraction Layer (EAL) implementations - in eal/ folder
    • eal/cr50 - implementation for cr50
      • pinweaver_eal_types.h - cr50-specific EAL API types
      • pinweaver_eal.c - cr50 implementation of EAL
    • eal/tpm_storage - implementation for platforms that use TPM as PinWeaver data storage
      • pinweaver_eal_types.h - TPM-storage-specific EAL API types
      • pinweaver_eal_tpm.h - additional EAL functions required by TPM storage
      • pinweaver_eal_linux.c - implementation of non-storage EAL methods for Linux case
      • tpm_storage_stubs.c - empty implementation of storage EAL methods
      • tpm_storage.c - implementation of storage EAL methods on top of TSS
      • mini_trunks/ - mini-TSS (TPM client software stack) used by TPM storage implementation
        • created from trunks TSS used by ChromeOS reduced to the minimal required set of TPM commands and ported from C++ to C
        • relies on pinweaver_eal.h + pinweaver_eal_tpm.h EAL methods
        • TSS API is defined in tss.h + *authorization_delegate.h

A platform implementation that uses TPM storage EAL option needs to implement all EAL methods implemented in pinweaver_eal_linux.c (or use it as-is, if Linux compatible).
