Also inline necessary functionality from `sndhdr` into `email.mime.audio` for `MIMEAudio`.

The openfp functions of aifp, sunau, and wave had pointed to the open
function of each module since 1993 as a matter of backwards
compatibility. In the case of aifc.openfp, it was both undocumented
and untested. This change begins the formal deprecation of those
openfp functions, with their removal coming in 3.9.
This additionally adds a TODO in test_pyclbr around using aifc.openfp,
though it shouldn't be changed until removal in 3.9.
- fix "h[sbseek] == b'\1'" and "ratecode = ord(h[sbseek+4])" in test_voc()
- avoid division by zero
- use startswith method: replace h[:2] == b'BM' by h.startswith(b'BM')
- use aifc.open() instead of old aifc.openfp()
- use ord(b'P') instead of ord('P')
modules have unittests AFAICT, and I'm not improving things here, but these
changes make a bunch of email package tests succeed, and command line testing
against real files seems to make things better.
Added an __main__ section to imghdr.py so that it can be run from the command
line similarly to sndhdr.py. Someone else can figure out a better -m way of
doing this.
In sndhdr.py do a couple of very minor cleanups, and use a with statement to
not wait for gc to close the file.
There's one major and one minor category still unfixed:
doctests are the major category (and I hope to be able to augment the
refactoring tool to refactor bona fide doctests soon);
other code generating print statements in strings is the minor category.
(Oh, and I don't know if the compiler package works.)
also modified check_all function to suppress all warnings since they aren't
relevant to what this test is doing (allows quiet checking of regsub, for
instance)
