This version includes a lot of the changes that were pointed out in
the review of the previous versions.  I apologize for rushing things
in to make it before the conference break.

Changes from v4:

- removed RESET handling, which will use a dedicated kernel API

- cleaned up stubs with respect to bisection, moving the definition
  of CONFIG_SGX at the beginning of the series [Philippe]

- created new header include/hw/i386/hostmem-epc.h and used
  HostMemoryBackendEpc when applicable in the API

- changed "Since" documentation from 6.1 to 6.2 [Eric]

- moved pc_machine_init_sgx_epc to patch 13 ("i386: Update SGX CPUID
  info according to hardware/KVM/user input")

- define x86_cpu_set_sgxlepubkeyhash even for user-mode emulation
  [Philippe]

- converted documentation to rST [Peter]

- cleaned up QMP/HMP commands [Daniel]

- fixed stubs for QMP/HMP commands for --disable-kvm and non-Linux builds

Gitlab CI has been tested already and passes.
