Jim Mussared 0e7bfc88c6 all: Use mp_obj_malloc everywhere it's applicable.
This replaces occurences of

    foo_t *foo = m_new_obj(foo_t);
    foo->base.type = &foo_type;

with

    foo_t *foo = mp_obj_malloc(foo_t, &foo_type);

Excludes any places where base is a sub-field or when new0/memset is used.

Damien George caaff940a2 extmod/uasyncio: Rename and merge TaskQueue push/pop methods.
These are internal names and can be safely renamed without affecting user
code.  push_sorted() and push_head() are merged into a single push()
method, which is already how the C version is implemented.  pop_head() is
simply renamed to pop().

The changes are:
- q.push_sorted(task, t) -> q.push(task, t)
- q.push_head(task) -> q.push(task)
- q.pop_head() -> q.pop()

The shorter names and removal of push_head() leads to a code size reduction
of between 40 and 64 bytes on bare-metal targets.

Jon Bjarni Bjarnason 919f696ad2 extmod/modusocket: Implement optional socket.listen backlog argument.
This follows the CPython change: https://bugs.python.org/issue21455

Socket listen backlog defaults to 2 if not given, based on most bare metal
targets not having many resources for a large backlog.  On UNIX it defaults
to SOMAXCONN or 128, whichever is less.

Damien George 90aaf2dbef extmod/uasyncio: Fix gather cancelling and handling of exceptions.
The following fixes are made:
- cancelling a gather now cancels all sub-tasks of the gather (previously
  it would only cancel the first)
- if any sub-task of a gather raises an exception then the gather finishes
  (previously it would only finish if the first sub-task raised)

All variants now use extmod/moduos.c as their uos module implementation.
In particular this means they all have MICROPY_VFS enabled and use VfsPosix
for their filesystem.

As part of this, the available functions in uos become more consistent with
other ports:
- coverage variant gets uos.urandom
- minimal and standard variant get: unlink, chdir, getcwd, listdir

Jim Mussared 341158c251 extmod/nimble: Add "memory stalling" mechanism for l2cap_send.
When l2cap_send detects that the sys mempool is running low (used to store
the outgoing HCI payloads), it will report stalled back to the application,
and then only unstall once these HCI payloads have been sent.

This prevents a situation where a remote receiver with very large MTU can
cause NimBLE to queue up more than MYNEWT_VAL_MSYS_1_BLOCK_COUNT (i.e. 12)
payloads, causing further attempts to send to fail with ENOMEM (even though
the channel is not stalled and we have room in the channel mbufs). The
regular credit/stall flow control is not effective here because the
receiver's MTU is large enough that it will not activate (i.e. there are
lots of credits available).

Thresholds of 1/2 (stall) and 1/4 (unstall) chosen to allow headroom for
other payloads (e.g. notifications) and that when a regular stall occurs it
might keep sending (and creating more payloads) in the background.

Damien George 7ec95c2768 extmod/uasyncio: Get addr and bind server socket before creating task.
Currently when using uasyncio.start_server() the socket configuration is
done inside a uasyncio.create_task() background function.  If the address
and port are already in use however this throws an OSError which cannot be
cleanly caught behind the create_task().

This commit moves the getaddrinfo and socket binding to the start_server()
function, and only creates the task if that succeeds.  This means that any
OSError from the initial socket configuration is propagated directly up the
call stack, compatible with CPython behaviour.

See #7444.

The introduced TASK_PAIRHEAP macro's conditional (x ? &x->i : NULL)
assembles (under amd64 gcc 8.3 -Os) to the same as &x->i, since i is the
initial field of the struct.  However, for the purposes of undefined

Damien George 514bf1a191 extmod/uasyncio: Fix race with cancelled task waiting on finished task.
This commit fixes a problem with a race between cancellation of task A and
completion of task B, when A waits on B.  If task B completes just before
task A is cancelled then the cancellation of A does not work.  Instead,
the CancelledError meant to cancel A gets passed through to B (that's
expected behaviour) but B handles it as a "Task exception wasn't retrieved"
scenario, printing out such a message (this is because finished tasks point
their "coro" attribute to themselves to indicate they are done, and
implement the throw() method, but that method inadvertently catches the
CancelledError).  The correct behaviour is for B to bounce that
CancelledError back out.

This bug is mainly seen when wait_for() is used, and in that context the
symptoms are:
- occurs when using wait_for(T, S), if the task T being waited on finishes
  at exactly the same time as the wait-for timeout S expires
- task T will have run to completion
- the "Task exception wasn't retrieved message" is printed with
  "<class 'CancelledError'>" as the error (ie no traceback)
- the wait_for(T, S) call never returns (it's never put back on the
  uasyncio run queue) and all tasks waiting on this are blocked forever
  from running
- uasyncio otherwise continues to function and other tasks continue to be
  scheduled as normal

The fix here reworks the "waiting" attribute of Task to be called "state"
and uses it to indicate whether a task is: running and not awaited on,
running and awaited on, finished and not awaited on, or finished and
awaited on.  This means the task does not need to point "coro" to itself to
indicate finished, and also allows removal of the throw() method.

A benefit of this is that "Task exception wasn't retrieved" messages can go
back to being able to print the name of the coroutine function.

Fixes issue #7386.

Macarthur Inbody 34d4dab683 extmod/modurandom: Add error message when getrandbits has bad value.
The random module's getrandbits() method didn't give a proper error message
when calling it with a value that was outside of the range of 1-32, which
can lead to confusion using this function (which under CPython can accept
numbers larger than 32).  Now instead of simply giving a ValueError it
gives an error message that states that the number of bits is constrained.

Also, since the random module's functions getrandbits() and randint()
differ from CPython, tests have been added to describe these differences.
For getrandbits the relevant documentation is shown and added to the docs.
The same is given for randint method so that the information is more easily
found.

Finally, since the int object lacks the bit_length() method there is a test
for that method also to include within the docs, showing the difference to
CPython.

This commits adds a new MICROPY_PY_BLUETOOTH_ENABLE_GATT_CLIENT

This also fixes a bug in the NimBLE bindings where a notification
or indication would not be received by a peripheral (acting as client)
as gap_event_cb wasn't handling it. Now both central_gap_event_cb
and peripheral_gap_event_cb share the same common handler for these

Jim Mussared 47d02b3104 extmod/nimble: Improve the flow control for l2cap recv path.
If the _IRQ_L2CAP_RECV handler does the actual consumption of the incoming
data (i.e. via l2cap_recvinto), rather than setting a flag for
non-scheduler-context to handle it later, then two things can happen:

- It can starve the VM (i.e. the scheduled task never terminates).  This is
  because calling l2cap_recvinto will empty the rx buffer, which will grant
  more credits to the channel (an HCI command), meaning more data can
  arrive.  This means that the loop in hal_uart.c that keeps reading HCI
  data from the uart and executing NimBLE events as they are created will
  not terminate, preventing other VM code from running.

- There's no flow control (i.e. data will arrive too quickly).  The channel
  shouldn't be given credits until after we return from scheduler context.

It's preferable that no work is done in scheduler/IRQ context.  But to
prevent this being a problem this commit changes l2cap_recvinto so that if
it is called in IRQ context, and the Python handler empties the rx buffer,
then don't grant credits until the Python handler is complete.

Damien George b505971069 extmod/uasyncio: Fix cancellation handling of wait_for.
This commit switches the roles of the helper task from a cancellation task
to a runner task, to get the correct semantics for cancellation of
wait_for.

Some uasyncio tests are now disabled for the native emitter due to issues
with native code generation of generators and yield-from.

Fixes #5797.

Damien George 309dfe39e0 extmod/uasyncio: Add Task.done() method.
This is added because task.coro==None is no longer the way to detect if a
task is finished.  Providing a (CPython compatible) function for this
allows the implementation to be abstracted away.
