Jim Mussared dfe232d000 py/builtinimport: Remove weak links.
In order to keep "import umodule" working, the existing mechanism is
replaced with a simple fallback to drop the "u".

This makes importing of built-ins no longer touch the filesystem, which
makes a typical built-in import take ~0.15ms rather than 3-5ms.

(Weak links were added in c14a81662c)

Damien George 2283b6d68f py: Pass in address to compiled module instead of returning it.
This change makes it so the compiler and persistent code loader take a
mp_compiled_module_t* as their last argument, instead of returning this
struct.  This eliminates a duplicate context variable for all callers of
these functions (because the context is now stored in the
mp_compiled_module_t by the caller), and also eliminates any confusion
about which context to use after the mp_compile_to_raw_code or
mp_raw_code_load function returns (because there is now only one context,
that stored in mp_compiled_module_t.context).

Reduces code size by 16 bytes on ARM Cortex-based ports.

Laurens Valk a67989aa20 examples/usercmodule: Add example of a native C class.
This shows how ports can add their own custom types/classes.

It is part of the unix coverage build, so we can use it for tests too.

Jim Mussared 3cc6decfc4 py/py.mk: Make user-C-module handling self-contained in py.mk.
Removes the need for the port to add anything to OBJS or SRC_QSTR.

Also makes it possible for user-C-modules to differentiate between code
that should be processed for QSTR vs other files (e.g. helpers and
libraries).

David Lechner 81dbea1ce3 shared/readline: Use MP_REGISTER_ROOT_POINTER().
This uses MP_REGISTER_ROOT_POINTER() to register the readline_history root
pointer array used by shared/readline.c and removes the registration from
all mpconfigport.h files.

This also required adding a new MICROPY_READLINE_HISTORY_SIZE config option
since not all ports used the same sized array.

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.

Damien George efe23aca71 all: Remove third argument to MP_REGISTER_MODULE.
It's no longer needed because this macro is now processed after
preprocessing the source code via cpp (in the qstr extraction stage), which
means unused MP_REGISTER_MODULE's are filtered out by the preprocessor.

Jim Mussared c737cde947 docs: Replace ufoo with foo in all docs.
Anywhere a module is mentioned, use its "non-u" name for consistency.

The "import module" vs "import umodule" is something of a FAQ, and this
commit intends to help clear that up.  As a first approximation MicroPython
is Python, and so imports should work the same as Python and use the same
name, to a first approximation.  The u-version of a module is a detail that
can be learned later on, when the user wants to understand more and have
finer control over importing.

Existing Python code should just work, as much as it is possible to do that
within the constraints of embedded systems, and the MicroPython
documentation should match the idiomatic way to write Python code.

With universal weak links for modules (via MICROPY_MODULE_WEAK_LINKS) users
can consistently use "import foo" across all ports (with the exception of
the minimal ports).  And the ability to override/extend via "foo.py"
continues to work well.

Damien George d87f42b0e5 examples/usercmodules: Simplify user C module enabling.
It's a bit of a pitfall with user C modules that including them in the
build does not automatically enable them.  This commit changes the docs and
examples for user C modules to encourage writers of user C modules to
enable them unconditionally.  This makes things simpler and covers most use
cases.

See discussion in issue #6960, and also #7086.
