Unfortunately, the replacement was buggy. strncmp(s, "opt", ss - s) matches "o", "op" and "opt" on the command line, as ss - s may be shorter than the passed literal. Furthermore, parse_bool() is affected by this, so substrings such as "d", "e" and "o" are considered valid, with the latter being ambiguous between "on" and "off". Introduce a new strcmp-like function for the task, which looks for exact string matches, but declares success when the NUL of the literal matches a comma, colon or semicolon in the command line fragment. No change to the intended parsing functionality, but fixes cases where a partial string on the command line will inadvertently trigger options. A few areas were more than just a trivial change: * parse_irq_vector_map_param() gained some style corrections. * parse_vpmu_params() was rewritten to use the normal list-of-options form, rather than just fixing up parse_vpmu_param() and leaving the parsing being hard to follow. * Instead of making the trivial fix of adding an explicit length check in parse_bool(), use the length to select which token to we search for, which is more efficient than the previous linear search over all possible tokens.
