Thorsten von Eicken c21452a1d2 extmod/uasyncio: Attempt to write immediately in Stream.write method.
The main aim of this change is to reduce the number of heap allocations
when writing data to a stream.  This is done in two ways:

1. Eliminate appending of data when .write() is called multiple times
   before calling .drain().  With this commit, the data is written out
   immediately if the underlying stream is not blocked, so there is no
   accumulation of the data in a temporary buffer.

2. Eliminate copying of non-bytes objects passed to .write().  Prior to
   this commit, passing a bytearray or memoryview to .write() would always
   result in a copy of it being made and turned into a bytes object.  That
   won't happen now if the underlying stream is not blocked.

Also, this change makes .write () more closely implement the CPython
documented semantics: "The method attempts to write the data to the
underlying socket immediately.  If that fails, the data is queued in an
internal write buffer until it can be sent."

robert-hh 5f4539b0ca esp32/machine_uart: Implement the functionality of timeout_char arg.
Using it for the rx-timeout.  The value is given as ms, which is then
converted to character times.  A value of less than a character time will
cause the rx call to return immediately after 1 character, which may be
inefficient at high transmission rates.

David Lechner c118b5d0e4 extmod/extmod.mk: Separate out extmod file list from py.mk to extmod.mk.
This separates extmod source files from `py.mk`.  Previously, `py.mk`
assumed that every consumer of the py/ directory also wanted to include
extmod/.  However, this is not the case.  For example, building mpy-cross
uses py/ but doesn't need extmod/.

This commit moves all extmod-specific items from `py.mk` to `extmod.mk` and
explicitly includes `extmod.mk` in ports that use it.

The following changes are made:

- Guard entire file with MICROPY_PY_LWIP, so it can be included in the
  build while still being disabled (for consistency with other extmod
  modules).

- Add modlwip.c to list of all extmod source in py/py.mk and
  extmod/extmod.cmake so all ports can easily use it.

- Move generic modlwip GIT_SUBMODULES build configuration code from
  ports/rp2/CMakeLists.txt to extmod/extmod.cmake, so it can be reused by
  other ports.

- Remove now unnecessary inclusion of modlwip.c in EXTMOD_SRC_C in esp8266
  port, and in SRC_QSTR in mimxrt port.

Damien George a506335524 py/emit: Suppress unreachable bytecode/native code that follows jump.
This new logic tracks when an unconditional jump/raise occurs in the
emitted code stream (bytecode or native machine code) and suppresses all
subsequent code, until a label is assigned.  This eliminates a lot of
cases of dead code, with relatively simple logic.

This commit combined with the previous one (that removed the existing
dead-code finding logic) has the following code size change:

       bare-arm:   -16 -0.028%
    minimal x86:   -60 -0.036%

Damien George 0db046b67b py/vm: Change comparison for finally handler search from > to >=.
The search in these cases should include all finally handlers that are
after the current ip.  If a handler starts at exactly ip then it is
considered "after" the ip.  This can happen when END_FINALLY is followed
immediately by a finally handler (from a different finally).

Consider the function:

    def f():
        try:
            return 0
        finally:
            print(1)

The current bytecode emitter generates the following code:

    00 SETUP_FINALLY 5
    02 LOAD_CONST_SMALL_INT 0
    03 RETURN_VALUE
    04 LOAD_CONST_NONE              ****
    05 LOAD_GLOBAL print
    07 LOAD_CONST_SMALL_INT 1
    08 CALL_FUNCTION n=1 nkw=0
    10 POP_TOP
    11 END_FINALLY
    12 LOAD_CONST_NONE
    13 RETURN_VALUE

The LOAD_CONST_NONE marked with **** is dead code because it follows a
RETURN_VALUE, and nothing jumps to this LOAD_CONST_NONE.  If the emitter
could remove this this dead code it would produce:

    00 SETUP_FINALLY 4
    02 LOAD_CONST_SMALL_INT 0
    03 RETURN_VALUE
    04 LOAD_GLOBAL print
    06 LOAD_CONST_SMALL_INT 1
    07 CALL_FUNCTION n=1 nkw=0
    09 POP_TOP
    10 END_FINALLY
    11 LOAD_CONST_NONE
    12 RETURN_VALUE

In this case the finally block (which starts at offset 4) immediately
follows the RETURN_VALUE.  When RETURN_VALUE executes ip will point to
offset 4 in the bytecode (because the dispatch of the opcode does *ip++)
and so the finally handler will only be found if a >= comparison is used.

It's a similar story for break/continue:

    while True:
        try:
            break
        finally:
            print(1)

Although technically in this case the > comparison still works because the
extra byte from the UNWIND_JUMP (encoding the number of exception handlers
to unwind) doesn't have a *ip++ (just a *ip) so ip remains pointing within
the UNWIND_JUMP opcode, and not at the start of the following finally
handler.  Nevertheless, the change is made to use >= for consistency with
the RETURN_VALUE change.
