8b16be9185 Remove "All rights reserved" string headers
Many of the license and Intel copyright headers include the "All rights
reserved" string. It is not relevant in the context of the BSD-3-Clause
license that the code is released under. This patch removes those strings
throughout the code (hypervisor, devicemodel and misc).

e254be150a HV: rewrite memcpy_s to be iso c11 compliant
Per C11 standard (ISO/IEC 9899:2011): K.3.7.1.1

1. Copying shall not take place between objects that overlap;
2. If there is a runtime-constraint violation, the memcpy_s function stores
   zeros in the first s1max characters of the object;
3. The memcpy_s function returns zero if there was no runtime-constraint
   violation. Otherwise, a nonzero value is returned.

b2c6cf7753 hv: refine retpoline speculation barriers
Per Section 4.4 Speculation Barriers, in
  "Retpoline: A Branch Target Inject Mitigation" white paper,
  "LFENCE instruction limits the speculative execution that
  a processor implementation can perform around the LFENCE,
  possibly impacting processor performance,but also creating
  a tool with which to mitigate speculative-execution
  side-channel attacks."
