5da8de2b66 extmod/modlwip: Fix error codes for duplicate calls to connect().
If socket is already connected, POSIX requires returning EISCONN. If
connection was requested, but not yet complete (for non-blocking
socket), error code is EALREADY.

d4cd4831b0 extmod/vfs_fat: Replace listdir() with implementation of ilistdir().
VfsFat no longer has the listdir() method.  Rather, if listdir()
functionality is needed then one should use uos.listdir() which will call
VfsFat.ilistdir().

c9a3a68a49 extmod/vfs: Allow a VFS to be mounted at the root dir.
This patch allows mounting of VFS objects right at the root directory, eg
os.mount(vfs, '/').  It still allows VFS's to be mounted at a path within
the root, eg os.mount(vfs, '/flash'), and such mount points will override
any paths within a VFS that is mounted at the root.

5db55e63f3 extmod/modlwip: ioctl POLL: Fix handling of peer closed socket.
Peer-closed socket is both readable and writable: read will return EOF,
write - error. Without this poll will hang on such socket.

Note that we don't return POLLHUP, based on argumentation in
http://www.greenend.org.uk/rjk/tech/poll.html that it should apply to
deeper disconnects, for example for networking, that would be link layer
disconnect (e.g. WiFi went down).

61616e84ce extmod/machine_signal: Rename "inverted" arg to "invert", it's shorter.
A shorter name takes less code size, less room in scripts and is faster to
type at the REPL.

Tests and HW-API examples are updated to reflect the change.

605ff91efd extmod/machine_signal: Support all Pin's arguments to the constructor.
This implements the orginal idea is that Signal is a subclass of Pin, and
thus can accept all the same argument as Pin, and additionally, "inverted"
param. On the practical side, it allows to avoid many enclosed parenses for
a typical declararion, e.g. for Zephyr:

Signal(Pin(("GPIO_0", 1))).

Of course, passing a Pin to Signal constructor is still supported and is the
most generic form (e.g. Unix port will only support such form, as it doesn't
have "builtin" Pins), what's introduces here is just practical readability
optimization.

"value" kwarg is treated as applying to a Signal (i.e. accounts for possible
inversion).

468c6f9da1 extmod/modframebuf: Make monochrome bitmap formats start with MONO_.
MONO_xxx is much easier to read if you're not familiar with the code.
MVLSB is deprecated but kept for backwards compatibility, for the time
being.

This patch also updates the associated docs and tests.

b6c7e4b143 all: Use full path name when including mp-readline/timeutils/netutils.
This follows the pattern of how all other headers are now included, and
makes it explicit where the header file comes from.  This patch also
removes -I options from Makefile's that specify the mp-readline/timeutils/
netutils directories, which are no longer needed.

e9d7c3ea0e modutimeq: Add peektime() function (provisional).
Allows to get event time for a head item in the queue. The usecase
if waiting for the next event *OR* I/O completion. I/O completion may
happen before event triggers, and then wait should continue for the
remaining event time (or I/O completion may schedule another earlier
event altogether).

The new function has a strongly provisional status - it may be converted
to e.g. peek() function returning all of the event fields, not just time.

2e3fc77809 extmod/utime_mphal: Don't exit/enter the GIL in generic sleep functions.
GIL behaviour should be handled by the port.  And ports probably want to
define sleep_us so that it doesn't release the GIL, to improve timing
accuracy.

1831034be1 py: Allow lexer to raise exceptions during construction.
This patch refactors the error handling in the lexer, to simplify it (ie
reduce code size).

A long time ago, when the lexer/parser/compiler were first written, the
lexer and parser were designed so they didn't use exceptions (ie nlr) to
report errors but rather returned an error code.  Over time that has
gradually changed, the parser in particular has more and more ways of
raising exceptions.  Also, the lexer never really handled all errors without
raising, eg there were some memory errors which could raise an exception
(and in these rare cases one would get a fatal nlr-not-handled fault).

This patch accepts the fact that the lexer can raise exceptions in some
cases and allows it to raise exceptions to handle all its errors, which are
for the most part just out-of-memory errors during construction of the
lexer.  This makes the lexer a bit simpler, and also the persistent code
stuff is simplified.

What this means for users of the lexer is that calls to it must be wrapped
in a nlr handler.  But all uses of the lexer already have such an nlr
handler for the parser (and compiler) so that doesn't put any extra burden
on the callers.

0a3ac07ec7 extmod/vfs: Rewrite path lookup algo to support relative paths from root.
For example, if the current directory is the root dir then this patch
allows one to do uos.listdir('mnt'), where 'mnt' is a valid mount point.
Previous to this patch such a thing would not work, on needed to do
uos.listdir('/mnt') instead.

830ce74f32 extmod/modutimeq: Make scheduling fair (round-robin).
By adding back monotonically increasing field in addition to time field.
As heapsort is not stable, without this, among entried added and readded
at the same time instant, some might be always selected, and some might
never be selected, leading to scheduling starvation.

ae8d867586 py: Add iter_buf to getiter type method.
Allows to iterate over the following without allocating on the heap:
- tuple
- list
- string, bytes
- bytearray, array
- dict (not dict.keys, dict.values, dict.items)
- set, frozenset

Allows to call the following without heap memory:
- all, any, min, max, sum

TODO: still need to allocate stack memory in bytecode for iter_buf.

ec7dc7f8d7 extmod/vfs: Allow to mount a block device, not just a VFS object.
If the mounted object doesn't have a "mount" method then assume it's a
block device and try to detect the filesystem.  Since we currently only
support FAT filesystems, the behaviour is to just try and create a VfsFat
object automatically, using the given block device.

181f7d1450 extmod/machine_signal: Implement Signal .on() and .off() methods.
Each method asserts and deasserts signal respectively. They are equivalent
to .value(1) and .value(0) but conceptually simpler (and may help to avoid
confusion with inverted signals, where "asserted" state means logical 0
output).

dee47949cc extmod/machine_spi: Remove EVENT_POLL_HOOK from soft-SPI transfer func.
SPI needs to be fast, and calling the EVENT_POLL_HOOK every byte makes it
unusable for ports that need to do non-trivial work in the EVENT_POLL_HOOK
call.  And individual SPI transfers should be short enough in time that
EVENT_POLL_HOOK doesn't need to be called.

If something like this proves to be needed in practice then we will need
to introduce separate event hook macros, one for "slow" loops (eg
select/poll) and one for "fast" loops (eg software I2C, SPI).

d5e9ab6e61 extmod/machine_pulse: Make time_pulse_us() not throw exceptions.
machine.time_pulse_us() is intended to provide very fine timing, including
while working with signal bursts, where each transition is tracked in row.
Throwing and handling an exception may take too much time and "signal loss".
So instead, in case of a timeout, just return negative value. Cases of
timeout while waiting for initial signal stabilization, and during actual
timing, are recognized.

The documentation is updated accordingly, and rewritten somewhat to clarify
the function behavior.
