On ARM the cpuid is dependent on the core type of the CPU in
question. The PMU was passed for the sake of the CPU map but this
means in places a temporary PMU is created just to pass a CPU
value. Just pass the CPU and fix up the callers.
As there are no longer PMU users in header.h, shuffle forward
declarations earlier to work around build failures.

ARM BIG.little has no notion of a constant CPUID for both core
types. To reflect this reality, change the get_cpuid function to also
pass in a possibly unused logical cpu.
If the dummy value (-1) is passed in then ARM can, as currently happens,
select the first logical CPU's "CPUID".
The changes to ARM getcpuid happen in a follow up change.

In the 32-bit platform, the second argument of getline is expectd to be
'size_t *'(aka 'unsigned int *'), but line_sz is of type
'unsigned long *'. Therefore, declare line_sz as size_t.

The get_cpuid_str function returns the string that contains values of
MVENDORID, MARCHID and MIMPID in hex format separated by coma.
The values themselves are taken from first cpu entry in "/proc/cpuid"
that contains "mvendorid", "marchid" and "mimpid".
