The `re_exec` symbol is the name of a FreeBSD regex function, so needs to
be renamed to avoid a clash when building on FreeBSD. (This clash was
fixed once before but then accidentally reintroduced by the u-module
renaming in 7f5d5c72718af773db751269c6ae14037b9c0727.)
Fixes issue #15430.

Being able to send data out in LSB format can be useful, and having support
in the low-level driver is much better than requiring Python code to
reorder the bits before sending them / after receiving them. In particular
if the hardware does not support the LSB format (eg RP2040) then one needs
to use the SoftSPI in LSB mode.
For this change a default definition of `MICROPY_PY_MACHINE_SPI_MSB/_LSB`
was added to `py/mpconfig.h`, making them available to all ports. The
identical defines in `esp32/mpconfigport.h` were deleted.
Resolves issues #5340, #11404.

The only AP security mode supported is actually WPA/WPA2 not WEP. The
firmware command `0x19` starts the AP using `WIFI_AUTH_WPA_WPA2_PSK`
mode.
There are no functional changes in this commit, it just fixes the constant
names and removes the useless sanity checks for WEP.

Enable support for cipher suites like
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, as suggested in
https://github.com/micropython/micropython/issues/14204#issuecomment-2024366349
and https://github.com/micropython/micropython/issues/10485#issuecomment-1396426824
Tests have been run on the top 500 domains from moz.com. Without this
patch, 155 out of 500 fail to connect because of TLS issues. This patch
fixes them all. And it seems all existing mbedtls flags are needed to get
good coverage of those top 500 domains.
The `ssl_poll.py` test has the cipher bits increased from 512 to 1024 in
its test key/cert so that it can work with ECDHE-RSA which is now the
chosen cipher.

If the socket timeout is 0 then a failed socket.connect() raises
EINPROGRESS (which is what the lwIP bindings already did), but if the

This implements network.ipconfig() and network.WLAN.ipconfig() when the
ninaw10 driver is used for WLAN.
Due to a omission in the ninaw10 driver stack, setting the DNS address has

eventually.

This adds support to use the Nagle algorithm implemented already in lwIP to
determine when TCP data should be sent.
As currently written, MicroPython will only create packets if there is <25%
remaining in the send buffer. Using it, sending a small message of ~50
bytes will not trigger output of the message on the network. So it will
remained queued until the TCP interval timer expires, which can be up to
500ms.
Using Nagle's algorithm, the first write, no matter how small, will
generate a packet on the network. And sending lots of data still makes
efficient use of the link.
In addition to this, an application designer may choose to always create
packets for every write by setting the TCP_NODELAY socket option. That's
also implemented in this commit.
The W5100 and W5100S only have 4 available sockets and 16kB of socket
buffer. Allocating 16kB to either the receive or transmit buffer of a
single socket is not allowed, so the current setup does not change the
allocation for socket 0 from the reset default. ctlwizchip is returning -1
to indicate the error, but the response isn't being inspected and probably
doesn't need to be.

Other constants such as `machine.Pin.OUT` are defined on the class that
uses them, rather than at the module level. This commit makes that the
case for WLAN network interfaces, adding IF_xxx and SEC_xxx constants.
The SEC_xxx constants are named as such to match the `security` keyword
that they are used with. And the IF_xxx constants have IF as a prefix so
they are grouped together as names.
This scheme of putting constants on the class means that only the available
features (eg security configurations) are made available as constants. It
also means that different network interfaces (eg WLAN vs LAN) can keep
their own specific constants within their class, such as PHY_xxx for LAN.

This commit implements a new <AbstractNIC>.ipconfig() function for the NIC
classes that use lwIP, to set and retrieve network configuration for a NIC.
Currently this method supports:
- ipconfig("addr4"): obtain a tuple (addr, netmask) of the currently
configured ipv4 address
- ipconfig("addr6"): obtain a list of tuples (addr, state,
prefered_lifetime, valid_lifetime) of all currently active ipv6
addresses; this includes static, slaac and link-local addresses
- ipconfig("has_dhcp4"): whether ipv4 dhcp has supplied an address
- ipconfig("has_autoconf6"): if there is a valid, non-static ipv6 address
- ipconfig(addr4="1.2.3.4/24"): to set the ipv4 address and netmask
- ipconfig(addr6="2a01::2"): to set a static ipv6 address; note that this
does not configure an interface route, as this does not seem supported by
lwIP
- ipconfig(autoconf6=True): to enable ipv6 network configuration with slaac
- ipconfig(gw4="1.2.3.1"): to set the ipv4 gateway
- ipconfig(dhcp4=True): enable ipv4 dhcp; this sets ipv4 address, netmask,
gateway and a dns server
- ipconfig(dhcp4=False): stops dhcp, releases the ip, and clears the
configured ipv4 address.
- ipconfig(dhcp6=True): enable stateless dhcpv6 to obtain a dns server
There is also a new global configuration function network.ipconfig() that
supports the following:
- network.ipconfig(dns="2a01::2"): set the primary dns server (can be a
ipv4 or ipv6 address)
- network.ipconfig(prefer=6): to prefer ipv6 addresses to be returned as
dns responses (falling back to ipv4 if the host does not have an ipv6
address); note that this does not flush the dns cache, so if a host is
already in the dns cache with its v4 address, subsequent lookups will
return that address even if prefer=6 is set
This interface replaces NIC.ifconfig() completely, and ifconfig() should be
marked as deprecated and removed in a future version.

The STATIC macro was introduced a very long time ago in commit
d5df6cd44a. The original reason for this was
to have the option to define it to nothing so that all static functions
become global functions and therefore visible to certain debug tools, so
one could do function size comparison and other things.
This STATIC feature is rarely (if ever) used. And with the use of LTO and
heavy inline optimisation, analysing the size of individual functions when
they are not static is not a good representation of the size of code when
fully optimised.
So the macro does not have much use and it's simpler to just remove it.
Then you know exactly what it's doing. For example, newcomers don't have
to learn what the STATIC macro is and why it exists. Reading the code is
also less "loud" with a lowercase static.
One other minor point in favour of removing it, is that it stops bugs with
`STATIC inline`, which should always be `static inline`.
Methodology for this commit was:
1) git ls-files | egrep '\.[ch]$' | \
xargs sed -Ei "s/(^| )STATIC($| )/\1static\2/"
2) Do some manual cleanup in the diff by searching for the word STATIC in
comments and changing those back.
3) "git-grep STATIC docs/", manually fixed those cases.
4) "rg -t python STATIC", manually fixed codegen lines that used STATIC.

This sets the BLE key distribution parameters at runtime. This isn't
needed in most ports since we already set the default values in
`extmod/nimble/syscfg/syscfg.h`; however in the ESP32 port that
headerfile is not used, and the default values in the ESP-IDF don't
enable key distribution nor can we change those defaults via
`sdkconfig`. Thus we're setting these values explicitly at runtime.

This moves the runtime initialisation of `ble_hs_cfg` to happen after
`nimble_port_init()`. That is consistent with the order used in NimBLE
examples. On the ESP32 port this is needed because the ESP-IDF sets up
the default RAM secret store callbacks in its implementation of
`nimble_port_init()` (specifically, it calls `esp_nimble_init()` which
in turn calls `ble_store_ram_init()`). We want to override those with
our own callbacks to implement the `IRQ_[GS]ET_SECRET` events in Python.
