Eduardo Habkost 247c9de13f target-i386: Topology & APIC ID utility functions
This introduces utility functions for the APIC ID calculation, based on:
  Intel® 64 Architecture Processor Topology Enumeration
  http://software.intel.com/en-us/articles/intel-64-architecture-processor-topology-enumeration/

The code should be compatible with AMD's "Extended Method" described at:
  AMD CPUID Specification (Publication #25481)
  Section 3: Multiple Core Calcuation
as long as:
 - nr_threads is set to 1;
 - OFFSET_IDX is assumed to be 0;
 - CPUID Fn8000_0008_ECX[ApicIdCoreIdSize[3:0]] is set to
   apicid_core_width().

Unit tests included.

David Gibson fecccc4477 Add .gitignore for tests/
The new autotests in tests/ generate a number of files, both
executable and source, which are not caught by the existing .gitignore
files.  This patch adds a new .gitignore in tests/ which covers these.

[Changed 'rtc-test' to '*-test' so future tests do not need to be added
to .gitignore on a case-by-case basis.  Stefan]
