[PATCH v2 0/3] UefiCpuPkg, OvmfPkg: set maximum (V)CPU count dynamically

[Laszlo Ersek <lersek@redhat.com>]

This is version 2 of the series at
<https://lists.01.org/pipermail/edk2-devel/2016-November/005073.html>.

Changes in this version:

- Patches #1 and #2 from v1 have been committed.

- Patches #3 and #4 from v1 have been reworked based on Jeff's advice.
  Namely, we now set PcdCpuMaxLogicalProcessorNumber and
  PcdCpuApInitTimeOutInMicroSeconds dynamically, rather than adding a
  new PCD. The method of waiting has been changed too, we now wait for
  the CPUs and the timeout simultaneously.

- Making PcdCpuMaxLogicalProcessorNumber actually dynamic required
  changes for PiSmmCpuDxeSmm too, so a new patch has been inserted at
  the front.
