libxl: extend pCPUs specification for vcpu-pin.
Allow for "^<cpuid>" syntax while specifying the pCPUs list
during a vcpu-pin. This enables doing the following:
xl vcpu-pin 1 1 0-4,^2
and achieving:
xl vcpu-list
Name ID VCPU CPU State Time(s) CPU Affinity
...
Squeeze_pv 1 1 3 -b- 2.4 0-1,3-4
...
Negative ranges are also supported, such as "0-4,^1-2" to
mean "0,3-4"
