__pmParseDebug parses spec assuming it to be a comma separated list
of PCP debug flags.
Each flag may be specified as an integer or the trailing portion of
the symbolic name of the corresponding flag as reported by pmdbg(1).
Symbolic names are stripped of the ``DBG_TRACE_'' prefix and may
appear in either case.
As a special case, the values ``-1'' and ``ALL'' are treated as
synonyms for turning on all bits except the sign bit in the result,
i.e. INT_MAX from <limits.h>.
For example the debug flag DBG_TRACE_FETCH is defined in
/usr/include/pcp/impl.h and may be specified in spec as 2, FETCH or
If successful, __pmParseDebug returns the value computed by the bit-
wise ``or'' of each flag in the spec, suitable for assigning to the
global debug trace control variable pmDebug. Otherwise the return
value is less than 0 to indicate a parsing error.
