This allows default config terms to be provided for a PMU. So, for
example, when the Intel PT PMU is added, it will be possible to specify:
intel_pt//
which will be the same as:
intel_pt/tsc=1,noretcomp=0/
meaning that the trace should contain TSC timestamps and perform 'return
compression'.
An important consideration of this patch is that it must be possible to
overwrite the default values. That has meant changing the logic so that
a zero value can replace a non-zero value.

We were using a homebrew equivalent, use the macro that is used
everywhere for this function.

In tools/perf we use a convention where __ separates the struct name
from the function name for functions that operate on a struct instance.
Fix this usage by removing it from the struct parse_events_term and fix
also its associated functions.
