Follow up to 35dd959133fb233d75e9b3cddbf98b2ed01c6594, allows explicitly
adding the unix-ffi library path from the command line.
This option is needed when building unix-ffi manifests in micropython-lib
CI.

This reduces frozen code size by using the bytecode directly as the
`mp_proto_fun_t`.

Allows bytecode itself to be used instead of an mp_raw_code_t in the simple
and common cases of a bytecode function without any children.
This can be used to further reduce frozen code size, and has the potential
to optimise other areas like importing.

To simplify their access and reduce code size.
The `scope_flags` member is only ever used to determine if a function is a
generator or not, so make it reflect that fact as a bool type.

The `asm_n_pos_args` and `asm_type_sig` members of `mp_raw_code_t` are only
used for raw codes of type MP_CODE_NATIVE_ASM, which are rare, for example
in frozen code. So using a truncated `mp_raw_code_t` in these cases helps
to reduce frozen code size on targets that have MICROPY_EMIT_INLINE_ASM
enabled.
With this, change in firmware size of RPI_PICO builds is -648.

The mp_raw_code_t struct has been reordered and some members resized. The
`n_pos_args` member is renamed to `asm_n_pos_args`, and `type_sig` renamed
to `asm_type_sig` to indicate that these are used only for the inline-asm
emitters. These two members are also grouped together in the struct.
The justifications for resizing the members are:
- `fun_data_len` can be 32-bits without issue
- `n_children` is already limited to 16-bits by
`mp_emit_common_t::ct_cur_child`
- `scope_flags` is already limited to 16-bits by `scope_t::scope_flags`
- `prelude_offset` is already limited to 16-bits by the argument to
`mp_emit_glue_assign_native()`
- it's reasonable to limit the maximim number of inline-asm arguments to 12
(24 bits for `asm_type_sig` divided by 2)
This change helps to reduce frozen code size (and in some cases RAM usage)
in the following cases:
- 64-bit targets
- builds with MICROPY_PY_SYS_SETTRACE enabled
- builds with MICROPY_EMIT_MACHINE_CODE enabled but MICROPY_EMIT_INLINE_ASM
disabled
With this change, unix 64-bit builds are -4080 bytes in size. Bare-metal
ports like rp2 are unchanged (because mp_raw_code_t is still 32 bytes on
those 32-bit targets).

With these changes IPv6 works on the rp2 port (and possibly others that use
the lwIP socket implementation).
Things that have been tested and work:
- Neighbour solicitation for v6 link local address.
- Ping of v6 link-local address.
- Receiving a SLAAC address via router advertisement.
- Ping a v6 address allocated via SLAAC.
- Perform an outgoing connection to a routed v6-address (via default
gateway).
- Create a listening IPv6 wildcard socked bound to ::, and trying to access
it via link-local, SLAAC, and IPv4 (to ensure the dual-stack binding
works).
Things that could be improved:
- socket.socket().getaddrinfo only returns the v4 address. It could also
return v6 addresses (getaddrinfo is actively programmed to only return a
single address, and this is the v4-address by default, with fallback to
the v6 address if both are enabled).

The Python BLE IRQ handler will most likely run on the NimBLE task, so its
C stack must be large enough to accommodate reasonably complicated Python
code (eg a few call depths). So increase this stack size.
Also increase the headroom from 1024 to 2048 bytes. This is needed because
(1) the esp32 architecture uses a fair amount of stack in general; and (2)
by the time execution gets to setting the Python stack top via
`mp_stack_set_top()` in this interlock code, about 600 bytes of stack are
already used, which reduces the amount available for Python.
Fixes issue #12349.

PPP is not that commonly used, let it be turned off in the board config to
save space. It is still on by default.
On an basic ESP32-S3 build, turning off PPP with LWIP still on saves ~35 kB
of codend 4 kB of data.

Note that the BSS segment size includes all NOBITS sections in ELF file.
Some of these are aligned to 64kB chunk sized dummy blocks, I think for
alignment to MMU boundaries, and these went down by 1 block each, so 128
kiB of BSS is not really part of the binary size reduction.

For mimxrt, nrf, renesas-ra, rp2 and samd ports, this commit implements
similar behaviour to the stm32 port, where USB is only brought up after
boot.py completes execution.
Currently this doesn't add any useful functionality (and may break
workflows that depend on USB-CDC being live in boot.py), however it's a
precondition for more usable workflows with USB devices defined in
Python (allows setting up USB interfaces in boot.py before the device
enumerates for the first time).

The C99 standard states:
6.8.6.4 The return statement Constraints
A return statement with an expression shall not appear in a function
whose return type is void. A return statement without an expression
shall only appear in a function whose return type is void.

It's rare to freeze .mpy files without specifying a qstr header from a
firmware build, but it can be useful for testing, eg
`mpy-tool.py -f test.mpy`. Fix this case so static qstrs are properly
excluded from the frozen qstr list.

Similar to the previous commit but for MP_BLUETOOTH_IRQ_GATTC_READ_DONE:
the pending_value_handle needs to be reset before calling
mp_bluetooth_gattc_on_read_write_status(), which will call the Python IRQ
handler, which may in turn call back into BTstack to perform an action like
a write. In that case the pending_value_handle will need to be available
for the write/read/etc to proceed.
Fixes issue #13634.

This commit changes how library packages are searched for when a manifest
file is loaded: there is now simply a list of library paths that is
searched in order for the given package. This list defaults to the
main directories in micropython-lib, but can be added to -- either appended
or prepended -- by using `add_library()`.
In particular the way unix-ffi library packages are searched has changed,
because the `unix_ffi` argument to `require()` is now removed. Instead, if
a build wants to include packages from micropython-lib/unix-ffi, then it
must explicitly add this to the list of paths to search using:
add_library("unix-ffi", "$(MPY_LIB_DIR)/unix-ffi")
Work done in collaboration with Jim Mussared.

Similar to ruff.yaml, it's simpler to run the codespell command directly
from a workflow file. And developers can run codespell directly from the
command line without the need for options, or just use pre-commit.
This commit also applies a specific version to codespell, same as
pre-commit (introduced in a166d805f43).

The current `ssl` module has quite a few differences to the CPython
implementation. This change moves the MicroPython variant to a new `tls`
module and provides a wrapper module for `ssl` (in micropython-lib).
Users who only rely on implemented comparible behavior can continue to use
`ssl`, while users that rely on non-compatible behavior should switch to
`tls`. Then we can make the facade in `ssl` more strictly adhere to
CPython.
