f9ecd484bb esp8266: Change to use new generic VFS sub-system.
The VFS sub-system supports mounting of an arbitrary number of devices
(limited only by available RAM).  The internal flash is now mounted at
"/flash".

0d221775f5 esp8266/_boot.py: Decrease GC alloc threshold to quarter of heap size.
The idea behind decrease is: bytecode and other static data is also kept on
heap, and can easily become half of heap, then setting threshold to half of
heap will have null effect - GC will happen on complete heap exhaustion like
before. But exactly in such config maintaining heap defragmented is very
important, so lower threshold to accommodate that.

c141584e1e esp8266/_boot.py: Set GC alloc threshold to half of heap size.
Should keep good chunk of heap unfragmented, if a user application allows
that at all.

Leads to less fragmentation at teh time user code starts.

db80c0ed46 esp8266: Enable frozen bytecode, with scripts in modules/ subdir.
To start with, the critical scripts _boot.py and flashbdev.py are frozen
to improve performance and reduce RAM consumption.

Saves about 1000 bytes of heap RAM for a bare boot with filesystem.
