This adds a mechanism to track a pending notify/indicate operation that
is deferred due to the send buffer being full. This uses a tracked alloc
that is passed as the content arg to the callback.
This replaces the previous mechanism that did this via the global pending
op queue, shared with client read/write ops.

Makes gatts_notify and gatts_indicate work in the same way: by default they
send the DB value, but you can manually override the payload.
In other words, makes gatts_indicate work the same as gatts_notify.
Note: This removes support for queuing notifications and indications on
btstack when the ACL buffer is full. This functionality will be
reimplemented in a future commit.

This reverts commit 0613d3e3561a82fffa36594647ef916b19bc912b.
The value of CFG_TUD_CDC_EP_BUFSIZE should match the endpoint size,
otherwise data may stay in the lower layers of the USB stack (and not
passed up to the higher layers) until a total of CFG_TUD_CDC_EP_BUFSIZE
bytes have been received, which may not happen for a long time.
Fixes issue #11253.

This commit adds support for the `timeout` keyword argument to machine.I2C
on the rp2 port, following how it's done on other ports.
The main motivation here is avoid the interpreter crashing due to infinite
loops when SDA is stuck low, which is quite common if the board gets reset
while reading from an I2C device.
A default timeout of 50ms is chosen because it's consistent with:
- Commit a707fe50b085ec83722106609f6fd219faf9f030 which used a timeout of
50,000us for zero-length writes on the rp2 port.
- The machine.SoftI2C class which uses 50,000us as the default timeout.
- The stm32 port's hardware I2C, which uses 50,000us for
I2C_POLL_DEFAULT_TIMEOUT_US.
This commit also fixes the default timeout on the esp32 port to be
consistent with the above, and updates the documentation for machine.I2C to
document this keyword argument.

If a board defines a custom bootloader entry function it will be called
first, if not and the ROM API supports RUN bootloader API, then
`machine.bootloader()` will jump to the ROM serial downloader in USB mode.

This commit allows boards to disable Ethernet and keep the networking stack
enabled, to use an alternate networking interface, such as WiFi.
Note that the `network` and `socket` modules are now enabled by default for
a board.

This commit is necessary to make MicroPython work on this eval kit out of
the box, as the eval kit ships with the HyperFlash physically disconnected
from the bus (refer to the schematics or the user guide) and the QSPI
connected instead, but the fuses/board/pins are configured to boot from
internal flash (on FlexSPI2).
Note that enabling the HyperFlash is not trivial, as it requires soldering
and desoldering of many small footprint resistors and changing fuses.

The GreenHills preprocessor produces #line directives without a file name,
which the regular expression used to distiguish between
"# <number> file..." (GCC and similar) and "#line <number> file..."
(Microsoft C and similar) does not match, aborting processing.
Besides, the regular expression was unnecessarily wide, matching lines
containing a "#", followed by any number of 'l','i','n', and 'e'
characters.

This adds a new MODE_PYPROJECT, which gives basic support to allow
packaging a small subset of micropython-lib packages to PyPI.
This change allows a package in micropython-lib to:
- Add a "pypi" name to its metadata indicating that it's based on a PyPI
package.
- Add "stdlib" to its metadata indicating that it's a micropython version
of a stdlib package.
- Add a "pypi_publish" name to its metadata to indicate that it can be
published to PyPI (this can be different to the package name, e.g. "foo"
might want to be published as "micropython-foo").
When a package requires() another one, if it's in MODE_PYPROJECT then if
the package is from pypi then it will record that as a pypi dependency
instead (or no dependency at all if it's from stdlib).
Also allows require() to explicitly specify the pypi name.

Helps prevent the filesystem from getting formatted by mistake, among other
things. For example, on a Pico board, entering Ctrl+D and Ctrl+C fast many
times will eventually wipe the filesystem (without warning or notice).
Further rationale: Ctrl+C is used a lot by automation scripts (eg mpremote)
and UI's (eg Mu, Thonny) to get the board into a known state. If the board
is not responding for a short time then it's not possible to know if it's
just a slow start up (eg in _boot.py), or an infinite loop in the main
application. The former should not be interrupted, but the latter should.
The only way to distinguish these two cases would be to wait "long enough",
and if there's nothing on the serial after "long enough" then assume it's
running the application and Ctrl+C should break out of it. But defining
"long enough" is impossible for all the different boards and their possible
behaviour. The solution in this commit is to make it so that frozen
start-up code cannot be interrupted by Ctrl+C. That code then effectively
acts like normal C start-up code, which also cannot be interrupted.
Note: on the stm32 port this was never seen as an issue because all
start-up code is in C. But now other ports start to put more things in
_boot.py and so this problem crops up.

The dispatch active flag is only set once and never reset, so it will
always call the dispatch handler (once enabled), and it's not really
needed because it doesn't make things more efficient.
Also remove unused included headers.

Changes in this commit:
- Move the pwm_seq array to the p_config data structure. That prevents
potential resource collisions between PWM devices.
- Rename the keyword argument 'id' to 'device'. That's consistent with the
SAMD port as the other port allowing to specify it.

The NINA socket types have the same values as modnetwork, but that may
change in the future. So check the socket types passed to socket() and
convert them (if needed) to their respective Nina socket types.
Also remove the unnecessary socket type check code from bind(), as pointed
out by @robert-hh.

This is a follow up to d263438a6e365d3199494498a9b734cda29dde52, which
solved one problem (reset on disconnect) but introduced a second one (hang
in bootloader).
To solve both probles, False/False is needed for DTR/RTS for ESPxx, but
that would then block stm32 and others. Any unconditional combination of
DTR/RTS ends up blocking normal operation on some type of board or another.
A simple overview (for windows only):
DTR CTS ESP8266/ESP32 STM32/SAMD51/RP2040
unspecified unspecified Reset on disconnect OK
True False Hang in bootloader OK
False False OK No Repl
True True Reset on disconnect No Repl
False True Reset on disconnect No Repl
serial.manufacturer: wch.cn/Silicon Labs Microsoft
serial.description: USB-SERIAL CH340 / USB Serial Device
CP210x USB to UART
Bridge
The updated logic will only set the DTR/RTS signals for boards that do not
use standard Microsoft drivers (based on the manufacturer). It would also
be possible to check against a list of known driver manufactures (like
wch.cn or Silicon Labs) but this would require a list of known drivers for
all ports.

This is a best-effort implementation of write polling. It's difficult to
do correctly because if there are multiple output streams (eg UART and USB
CDC) then some may not be writeable while others are. A full solution
should also have a return value from mp_hal_stdout_tx_strn(), returning the
number of bytes written to the stream(s). That's also hard to define.
The renesas-ra and stm32 ports already implement a similar best-effort
mechanism for write polling.

If a multitest calls `multitest.output_metric(...)` then that output will
be collected separately, not considered as part of the test verification
output, and instead be printed at the end. This is useful for tests that
want to output performance/timing metrics that may change from one run to
the next.

Prior to this change, setting of UART parameters like parity, stop bits or
data bits did not work correctly. As suggested by @iabdalkader, adding
__DSB() fixes the problem, making sure that changes to the UART LCR_H
register are seen by the peripheral.
Note: the FIFO is already enabled in the call to uart_init(), so the call
to uart_set_fifo_enabled() is not required, but kept for visibility.
Fixes issue #10976.

This is intended to be used by the very outer caller of the VM/runtime. It
allows setting a top-level NLR handler that can be jumped to directly, in
order to forcefully abort the VM/runtime.
Enable using:
#define MICROPY_ENABLE_VM_ABORT (1)
Set up the handler at the top level using:
nlr_buf_t nlr;
nlr.ret_val = NULL;
if (nlr_push(&nlr) == 0) {
nlr_set_abort(&nlr);
// call into the VM/runtime
...
nlr_pop();
} else {
if (nlr.ret_val == NULL) {
// handle abort
...
} else {
// handle other exception that propagated to the top level
...
}
}
nlr_set_abort(NULL);
Schedule an abort, eg from an interrupt handler, using:
mp_sched_vm_abort();

For builds with DEBUG=1 and MICROPY_HW_ENABLE_UART_REPL=1, calling
stdio_init_all() in main() detaches the UART input from REPL. This change
suppresses calling stdio_init_all() then.

Previously, setting MICROPY_HW_ENABLE_USBDEV to 0 caused build errors. The
change affects the nrf and samd ports as well, so MICROPY_HW_ENABLE_USBDEV
had to be explicitly enabled there.
The configuration options MICROPY_HW_ENABLE_USBDEV and
MICROPY_HW_ENABLE_UART_REPL are independent, and can be enabled or disabled
by a board.
