David Lechner a565811f23 extmod/modbtree: Use buffer protocol for keys/values.
This changes the btree implementation to use the buffer protocol for
reading key/values in all methods.  `str` and `bytes` objects are not the
only bytes-like objects that could be used.

Documentation and tests are also updated.

Addresses issue #8748.

Damien George 90aaf2dbef extmod/uasyncio: Fix gather cancelling and handling of exceptions.
The following fixes are made:

  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)

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.

Jeff Epler 172fb5230a extmod/re1.5: Check and report byte overflow errors in _compilecode.
The generated regex code is limited in the range of jumps and counts, and
this commit checks all cases which can overflow given the right kind of
input regex, and returns an error in such a case.

This change assumes that the results that overflow an int8_t do not
overflow a platform int.

Damien George 71ea438561 extmod/vfs: Check block 0 and 1 when auto-detecting littlefs.
The superblock for littlefs is in block 0 and 1, but block 0 may be erased

filysystem type would fail for littlefs if block 0 did not contain a valid
superblock.  That is now fixed.

This test runs for 2.5 seconds and calls all utime functions every 100ms.
Then it checks if they returned enough different results.  All functions

The fourth parameter of readblocks() and writeblocks() must be optional to
support ports with MICROPY_VFS_FAT=1.  Otherwise mounting a bdev may fail
because looking for a FATFS will call readblocks() with only 3 parameters.

Damien George ca40eb0fda extmod/uasyncio: Delay calling Loop.call_exception_handler by 1 loop.
When a tasks raises an exception which is uncaught, and no other task
await's on that task, then an error message is printed (or a user function
called) via a call to Loop.call_exception_handler.  In CPython this call is
made when the Task object is freed (eg via reference counting) because it's
at that point that it is known that the exception that was raised will
never be handled.

MicroPython does not have reference counting and the current behaviour is
to deal with uncaught exceptions as early as possible, ie as soon as they
terminate the task.  But this can be undesirable because in certain cases
a task can start and raise an exception immediately (before any await is
executed in that task's coro) and before any other task gets a chance to
await on it to catch the exception.

This commit changes the behaviour so that tasks which end due to an
uncaught exception are scheduled one more time for execution, and if they
are not await'ed on by the next scheduling loop, then the exception handler
is called (eg the exception is printed out).

Arrowana 922f81dfd1 extmod/machine_mem: Only allow integers in machine.memX subscript.
Prior to this change machine.mem32['foo'] (or using any other non-integer
subscript) could result in a fault due to 'foo' being interpreted as an
integer.  And when writing code it's hard to tell if the fault is due to a
bad subscript type, or an integer subscript that specifies an invalid
memory address.

The type of the object used in the subscript is now tested to be an
integer by using mp_obj_get_int_truncated instead of
mp_obj_int_get_truncated.  The performance hit of this change is minimal,
and machine.memX objects are more for convenience than performance (there
are many other ways to read/write memory in a faster way),

Damien George 6f34800884 extmod/modurandom: Support urandom.seed() without an argument.
If a port provides MICROPY_PY_URANDOM_SEED_INIT_FUNC as a source of
randomness then this will be used when urandom.seed() is called without
an argument (or with None as the argument) to seed the pRNG.

Other related changes in this commit:
- mod_urandom___init__ is changed to call seed() without arguments, instead
  of explicitly passing in the result of MICROPY_PY_URANDOM_SEED_INIT_FUNC.
- mod_urandom___init__ will only ever seed the pRNG once (before it could
  seed it again if imported by, eg, random and then urandom).
- The Yasmarang state is moved to the BSS for builds where the state is
  guaranteed to be initialised on import of the (u)random module.
