This helps with Python-compatibility (see issue #4171) but doesn't
completely resolve it.
Now, `dir()` still computes any properties of the underlying object,
HOWEVER, if the property raises an exception this expression is
captured.
This ability to capture exceptions always existed in
`mp_load_method_protected`, we just need to turn it on via the
`catch_all_exc` boolean parameter.
Catch calls to legacy:
MP_REGISTER_MODULE(name, module, enable)
Emit a friendly error suggesting they be rewritten to:
MP_REGISTER_MODULE(name, module).

Make them CIRCUITPY_FULL_BUILD = 0 and rework the boards to have
the same modules enabled (ish.)
Also make ZLIB require FULL_BUILD and disable advanced `micropython`
module APIs by default on all builds.
This adds support for CIRCUITPY_WIFI_SSID and CIRCUITPY_WIFI_PASSWORD
in `/.env`. When both are defined, CircuitPython will attempt to
connect to the network even when user code isn't running. If the
user code attempts to a network with the same SSID, it will return
immediately. Connecting to another SSID will disconnect from the
auto-connected network. If the user code initiates the connection,
then it will be shutdown after user code exits. (Should match <8
behavior.)
This PR also reworks the default displayio terminal. It now supports
a title bar TileGrid in addition to the (newly renamed) scroll area.
The default title bar is the top row of the display and is positioned
to the right of the Blinka logo when it is enabled. The scroll area
is now below the Blinka logo.
The Wi-Fi auto-connect code now uses the title bar to show its
state including the IP address when connected. It does this through
the "standard" OSC control sequence `ESC ] 0 ; <s> ESC \` where <s>
is the title bar string. This is commonly supported by terminals
so it should work over USB and UART as well.

This file is not executable so shouldn't have the shebang line. This line
can cause issues when building on Windows msvc when the PyPython variable
is set to something other than "python", because it reverts back to using
the shebang line.
The top comment is also changed to """ style which matches all other
preprocessing scripts in the py/ directory.

Without this, newer versions of gcc (eg 11.2.0) used with -O2 can warn
about `q_ptr` being maybe uninitialized, because it doesn't know that there
is at least one qstr being written in to this (alloca'd) memory.
As part of this, change the type of `n` to `size_t` so the compiler knows
it's unsigned and can generate better code.

This was made redundant by f2040bfc7ee033e48acef9f289790f3b4e6b74e5, which
also did not update this function for the change to qstr-opcode encoding,
so it does not work correctly anyway.

Support for architecture-specific qstr linking was removed in
d4d53e9e114d779523e382c4ea38f0398e880aae, where native code was changed to
access qstr values via qstr_table. The only remaining use for the special
qstr link table in persistentcode.c is to support native module written in
C, linked via mpy_ld.py. But native modules can also use the standard
module-level qstr_table (and obj_table) which was introduced in the .mpy
file reworking in f2040bfc7ee033e48acef9f289790f3b4e6b74e5.
This commit removes the remaining native qstr liking support in
persistentcode.c's load_raw_code function, and adds two new relocation
options for constants.qstr_table and constants.obj_table. mpy_ld.py is
updated to use these relocations options instead of the native qstr link
table.

Profiling shows that `est_net_savings` is one of the highest costs of
the whole process. Approximately, you can save storage only if a word
appears more than once, and doing this greatly reduces the number
of `est_net_savings` calls. Locally, it reduces the time for this
specific build step by 50% on ports/unix coverage build, without
affecting the size of the generated binary.
This breaks the translation dependency to all of the other objects
and therefore speeds up subsequent builds. Now, even when the big
translate() function is inlined in the header, it only needs to be
optimized once.
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.

This cleans up the parsing of MP_REGISTER_MODULE() and generation of
genhdr/moduledefs.h so that it uses the same process as compressed error
string messages, using the output of qstr extraction.
This makes sure all MP_REGISTER_MODULE()'s that are part of the build are
correctly picked up. Previously the extraction would miss some (eg if you
had a mod.c file in the board directory for an stm32 board).
Build speed is more or less unchanged.
Thanks to @stinos for the ports/windows/msvc/genhdr.targets changes.

This allows the compile stage to optimize most of the translate()
function away and saves a ton of space (~40k on ESP). *However*, it
requires us to wait for the qstr output before we compile the rest
of our .o files. (Only qstr.o used to wait.)
This isn't as good as the current setup with LTO though. Trinket M0
loses <1k with this setup.
So, we should probably conditionalize this along with LTO.

The following changes are made:
- If MICROPY_VFS is enabled then mp_vfs_import_stat and mp_vfs_open are
automatically used for mp_import_stat and mp_builtin_open respectively.
- If MICROPY_PY_IO is enabled then "open" is automatically included in the
set of builtins, and points to mp_builtin_open_obj.
This helps to clean up and simplify the most common port configuration.

Everything should be using the keypad module instead.
Note: there are several boards that still had gamepadshift enabled. I
did not contact their authors to make sure they already switched to
keypad in their code and documentation. We should probably wait with
merging this for their go ahead.
The examples/natmod features0 and features1 examples now build and run on
ARMv6-M platforms. More complicated examples are not yet supported because
the compiler emits references to built-in functions like __aeabi_uidiv.

If __thumb2__ is defined by the compiler then .mpy files marked as ARMV6M
and above (up to ARMV7EMDP) are supported. If it's not defined then only
ARMV6M .mpy files are supported. This makes sure that on CPUs like
Cortex-M0+ (where __thumb2__ is not defined) only .mpy files marked as
ARMV6M can be imported.

This commit adjusts the asm_thumb_xxx functions so they can be dynamically
configured to use ARMv7-M instructions or not. This is available when
MICROPY_DYNAMIC_COMPILER is enabled, and then controlled by the value of
mp_dynamic_compiler.native_arch.
If MICROPY_DYNAMIC_COMPILER is disabled the previous behaviour is retained:
the functions emit ARMv7-M instructions only if MICROPY_EMIT_THUMB_ARMV7M
is enabled.
