closes bpo-31650: PEP 552 (Deterministic pycs) implementation (#4575)
Python now supports checking bytecode cache up-to-dateness with a hash of the
source contents rather than volatile source metadata. See the PEP for details.

While a fairly straightforward idea, quite a lot of code had to be modified due
to the pervasiveness of pyc implementation details in the codebase. Changes in
this commit include:

- The core changes to importlib to understand how to read, validate, and
  regenerate hash-based pycs.

- Support for generating hash-based pycs in py_compile and compileall.

- Modifications to our siphash implementation to support passing a custom
  key. We then expose it to importlib through _imp.

- Updates to all places in the interpreter, standard library, and tests that
  manually generate or parse pyc files to grok the new format.

- Support in the interpreter command line code for long options like
  --check-hash-based-pycs.

- Tests and documentation for all of the above.

R David Murray ced699b4c7 #24903: Remove misleading error message to fix regression.
Before the argparse conversion, compileall would (sometimes) accept multiple
paths when -d was specified.  Afterward, it does not.  The corresponding check
in the original code claimed to prevent multiple *directories* from being
specified...but it didn't really work even to do that.  So this patch fixes
the regression by invoking the consenting adults rule: if you specify a
combination of arguments to compileall that produces files with inconsistent
destdirs (which you could do before), it is on you.

Patch by Jake Garver.

R. David Murray 5317e9cd8d #10719: restore messages generated on invalid compileall args
Before the introduction of filename arguments to compileall it gave semi useful
messages about not being able to 'list' names that weren't valid directories.
This fix restores that behavior.  In addition to the test for this case, the
patch also adds a test for the default behavior of compileall when no arguments
are provided, and fixes a bug in one of the previously added tests.
