00137b8c11 py/map: Change hash-table allocation policy to be less aggressive. 
Small hash tables (eg those used in user class instances that only have a
few members) now only use the minimum amount of memory necessary to hold
the key/value pairs.  This can reduce performance for instances that have
many members (because then there are many reallocations/rehashings of the
table), but helps to conserve memory.

See issue #1760.

7d2c685544 esp8266/scripts/_boot: Mount block device on "" instead of "/". 
"" is the correct name of the root directory when mounting a device there
(as opposed to "/").  One can now do os.listdir('/') and open('/abc'), as
well as os.listdir() and open('abc').

0c1de1cdee py: Simplify "and" action within parser by making ident-rules explicit. 
Most grammar rules can optimise to the identity if they only have a single
argument, saving a lot of RAM building the parse tree.  Previous to this
patch, whether a given grammar rule could be optimised was defined (mostly
implicitly) by a complicated set of logic rules.  With this patch the
definition is always specified explicitly by using "and_ident" in the rule
definition in the grammar.  This simplifies the logic of the parser,
making it a bit smaller and faster.  RAM usage in unaffected.

0a2e9650f5 py: Add ability to have frozen persistent bytecode from .mpy files. 
The config variable MICROPY_MODULE_FROZEN is now made of two separate
parts: MICROPY_MODULE_FROZEN_STR and MICROPY_MODULE_FROZEN_MPY.  This
allows to have none, either or both of frozen strings and frozen mpy
files (aka frozen bytecode).

@dpgeorge was the original author of this patch, but @pohmelie made
changes to implement `async for` and `async with`.

19e3c9d53a esp8266/esp_mphal: Don't swallow exceptions in dupterm's read()/write(). 
The idea is that if dupterm object can handle exceptions, it will handle
them itself. Otherwise, object state can be compromised and it's better
to terminate dupterm session. For example, disconnected socket will keep
throwing exceptions and dump messages about that.
