f040685b0c py: Only store the exception instance on Py stack in bytecode try block. 
When an exception is raised and is to be handled by the VM, it is stored
on the Python value stack so the bytecode can access it.  CPython stores
3 objects on the stack for each exception: exc type, exc instance and
traceback.  uPy followed this approach, but it turns out not to be
necessary.  Instead, it is enough to store just the exception instance on
the Python value stack.  The only place where the 3 values are needed
explicitly is for the __exit__ handler of a with-statement context, but
for these cases the 3 values can be extracted from the single exception
instance.

This patch removes the need to store 3 values on the stack, and instead
just stores the exception instance.

Code size is reduced by about 50-100 bytes, the compiler and VM are
slightly simpler, generate bytecode is smaller (by 2 bytes for each try
block), and the Python value stack is reduced in size for functions that
handle exceptions.

7b901d6fb7 extmod/moduzlib: DecompIO: Add support for gzip-formatted streams. 
This uses extension introduced in CPython 3.5: if wbits (dictionary size
code) has value 16 + 8..15, it means that gzip-formatted stream expected.

6d310a5552 py/parse: Only replace constants that are standalone identifiers. 
This fixes constant substitution so that only standalone identifiers are
replaced with their constant value (if they have one).  I.e. don't
replace NAME in expressions like obj.NAME or NAME = expr.

e97df97600 py: Shrink mp_arg_t struct by using reduced-size integer members. 
qstrs ids are restricted to fit within 2 bytes already (eg in persistent
bytecode) so it's safe to use a uint16_t to store them in mp_arg_t.  And
the flags member only needs a maximum of 2 bytes so can also use uint16_t.

Savings in code size can be significant when many mp_arg_t structs are
used for argument parsing.  Eg, this patch reduces stmhal by 480 bytes.

ec078af985 extmod/machine_i2c: Add clock stretching support. 
When the clock is too fast for the i2c slave, it can temporarily hold
down the scl line to signal to the master that it needs to wait. The
master should check the scl line when it is releasing it after
transmitting data, and wait for it to be released.

This change has been tested with a logic analyzer and an i2c slace
implemented on an atmega328p using its twi peripheral, clocked at 8Mhz.
Without the change, the i2c communication works up to aboy 150kHz
frequency, and above that results in the slave stuck in an unresponsive
state. With this change, communication has been tested to work up to
400kHz.

fbddea929d py/showbc: Make printf's go to the platform print stream. 
The system printf is no longer used by the core uPy code.  Instead, the
platform print stream or DEBUG_printf is used.  Using DEBUG_printf in the
showbc functions would mean that the code can't be tested by the test
suite, so use the normal output instead.

This patch also fixes parsing of bytecode-line-number mappings.
