Jim Mussared e0bf4611c3 py: Only search frozen modules when '.frozen' is found in sys.path.
This changes makemanifest.py & mpy-tool.py to merge string and mpy names
into the same list (now mp_frozen_names).

The various paths for loading a frozen module (mp_find_frozen_module) and
checking existence of a frozen module (mp_frozen_stat) use a common
function that searches this list.

In addition, the frozen lookup will now only take place if the path starts
with ".frozen", which needs to be added to sys.path.

This fixes issues #1804, #2322, #3509, #6419.

Alexander Steffen 55f33240f3 all: Use the name MicroPython consistently in comments
There were several different spellings of MicroPython present in comments,
when there should be only one.

Paul Sokolovsky d7da2dba07 py/modio: Implement uio.resource_stream(package, resource_path).
The with semantics of this function is close to
pkg_resources.resource_stream() function from setuptools, which
is the canonical way to access non-source files belonging to a package
(resources), regardless of what medium the package uses (e.g. individual
source files vs zip archive). In the case of MicroPython, this function
allows to access resources which are frozen into the executable, besides
accessing resources in the file system.

This is initial stage of the implementation, which actually doesn't
implement "package" part of the semantics, just accesses frozen resources
from "root", or filesystem resource - from current dir.

Damien George 274952a117 py: Allow to stat and import frozen mpy files using new frozen "VFS".
Freezing mpy files using mpy-tool.py now works again.

Paul Sokolovsky fb742cdc12 py/{builtinimport,frozenmod}: Rework frozen modules support to support packages.
Now frozen modules is treated just as a kind of VFS, and all operations
performed on it correspond to operations on normal filesystem. This allows
to support packages properly, and potentially also data files.

This change also have changes to rework frozen bytecode modules support to
use the same framework, but it's not finished (and actually may not work,
as older adhox handling of any type of frozen modules is removed).

Damien George 31480fb91b py/frozenmod: Pass the source name of the frozen module to the lexer.
This allows for better error messages, since the name of the file (sans
.py) can now be printed when an exception occurs within a frozen script.

Damien George 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).

Paul Sokolovsky 640e0b221e py: Implement very simple frozen modules support.
Only modules (not packages) supported now. Source modules can be converted
to frozen module structures using tools/make-frozen.py script.
