Larry Hastings 2623c8c23c Issue #20530: Argument Clinic's signature format has been revised again.
The new syntax is highly human readable while still preventing false
positives.  The syntax also extends Python syntax to denote "self" and
positional-only parameters, allowing inspect.Signature objects to be
totally accurate for all supported builtins in Python 3.4.

Note that the meat of the test is contained in testcapi_long.h.
This is revolting, but delicate code duplication is worse: "almost
exactly the same" code is needed to test PY_LONG_LONG, but the ubiquitous
dependence on type names makes it impossible to use a parameterized
function. A giant macro would be even worse than this. A C++ template
would be perfect.
The "report an error" functions are deliberately not part of the #include
file: if the test fails, you can set a breakpoint in the appropriate
error function directly, and crawl back from there in the debugger.
