This commit allows switching SDK firmware:
nonos-sdk-pre-v3 shipped with release 2.5.0 has issues:
* Some boards show erratic behavior (radio connection is quickly lost), with an unknown cause.
These boards work well with previous nonos-sdk-2.2.1 firmware (#5736)
* Overall performances seem to have decreased (#5513)
This PR restores sdk2.2.1 (as in core-2.4.2).
SDK-pre-3.0 - which has brought long awaited fixes (WiFi sleep modes) - is still available through a menu option available only with generic board.
BREAKING
* new define `-DNONOSDK221=1` or `-DNONOSDK3V0=1`
* for external build systems: new library directory: `tools/sdk/lib/<version>/lib`
* PIO: variable `PIO_FRAMEWORK_ARDUINO_ESPRESSIF_SDK3` is needed for sdk-pre-v3.
Fix#5736
Per 'udp_set_multicast_netif_addr()' signature and comments in lwIP sources:
An IPv4 address designating a specific interface must be used.
When an IPv6 address is given, the matching IPv4 in the same interface must be selected.
fix e3bc3c226b (r32235572)
Because the constructors of the BSSL client and server add a reference
count to the stack_thunk, if there is no copy constructor defined then
the stack thunk reference count can get out of sync causing the stack
thunk memory to be freed while still in use. That could cause random
crashes or hangs.
Add a very basic copy constructor to the WiFiClientSecure and
WiFiServerSecure objects, using the default operator= to duplicate
simple types and shared_ptr classes.
The _cipher_list element (used only w/custom ciphers) could be freed
while still in use if copies of the WiFiClientSecure object were made.
Use a shared_ptr which will only free when the last reference is
deleted.
The axTLS compatibility mode calls allocate and store elements needed
for SSL connections (unlike normal BearSSL calls). These elements could
be freed mistakenly while still in use if copies of the WiFiClientSecure
were made by the app.
Convert to a separately managed shared_ptr to ensure they live as long
as any referencing objects before deletion.
Same done for the axTLS compatability for WiFiServerSecure.
Fixes#5701 WDTs and other issues with BearSSL::WiFiServerSecure
The BSSL server was creating the client it returns on a connection in a
way that caused the counter for the stack_thunk to get out of sync and
cause it to be freed improperly by having the destructor be called one
more time than the constructor. Looks like RVO.
Rewrite the ::available() function in order to avoid this issue with
help from @devyte.

Using a pluggable architecture, allow updates delivered via the Update
class to be verified as signed by a certificate. By using plugins, avoid
pulling either axTLS or BearSSL into normal builds.
A signature is appended to a binary image, followed by the size of the
signature as a 32-bit int. The updater takes a verification function
and checks this signature using whatever method it chooses, and if it
fails the update is not applied.
A SHA256 hash class is presently implemented for the signing hash (since
MD5 is a busted algorithm).
A BearSSLPublicKey based verifier is implemented for RSA keys. The
application only needs the Public Key, while to sign you can use
OpenSSL and your private key (which should never leave your control
or be deployed on any endpoints).
An example using automatic signing is included.
Update the docs to show the signing steps and how to use it in the
automatic and manual modes.
Also remove one debugging line from the signing tool.
Saves ~600 bytes when in debug mode by moving strings to PMEM
Windows can't run the signing script, nor does it normally have OpenSSL
installed. When trying to build an automatically signed binary, warn
and don't run the python.
Many objects now expect a WiFiClient* object to be passed to them and
potentially re-used multiple times (HTTPClient, others). Clearing the
authentication options on a ::stop means they can never reconnect.
Remove the option clearing in ::stop

* Add br_thunk_* calls to do ref counting, painting
Add reference counting br_thunk_add/del_ref() to replace stack handling code
in the class.
Add in stack painting and max usage calculation.

When a crash occurs while in the second stack, dump the BSSL stack and
then also the stack that it was called from (either cont or sys).
* Update stack dump to match decoder expectations
* Move thunk to code core for linkiage
The thunk code needs to be visible to the core routines, so move it to the
cores/esp8266 directory. Probably need to refactor the stack setup and the
bearssl portion to avoid dependency on bearssl libs in cores/esp8266
* Add 2nd stack dump utility routine
* Refactor once more, update stack size, add stress
Make stack_thunks generic, remove bearssl include inside of cores/esp8266.
Allocate the stack on a WiFiServerSecure object creation to avoid
fragmentation since we will need to allocate the stack to do any
connected work, anyway.
A stress test is now included which checks the total BearSSL second
stack usage for a variety of TLS handshake and certificate options
from badssl.org.
* Update to latest to-thunks branch
* Add BearSSL device test using stack stress
Run a series of SSL connection and transmission tests that stress
BearSSL and its stack usage to the device tests.
Modify device tests to include a possible SPIFFS generation and
upload when a make_spiffs.py file is present in a test directory.
* Use bearssl/master branch, not /to-thunks branch
Update to use the merged master branch of bearssl. Should have no code
changes.
BearSSLX509List, BearSSLSession, BearSSLPublicKey, and BearSSLPrivateKey
were all in the global namespace and not in the BearSSL:: one, due to an
oversight when they were originally created. Move them to the proper
namespace with the following mapping:
BearSSLX509List => BearSSL::X509List
BearSSLSession => BearSSL::Session
BearSSLPublicKey => BearSSL::PublicKey
BearSSLPrivateKey => BearSSL::PrivateKey
Fix bug introduced by #5167 which replaced delay() by yield().
That should have been esp_yield() which is the one delay()
calls and is safe from either SYS or CONT contexts.
Fixes#5237.
Allow the unused stack to be reset to the check value at any time in
the application, allowing for delta-stack calculations to be done.
Add ESP.resetFreeContStack() class method for general use.
Add in some dumping in the BearSSL_Validation example to show the
usage for those that care.

Print a warning when in debug mode when a BearSSL connection tries to
connect without having any defined authentication methods, since it will
fail.
Completely remove the empty axTLS compatibilty method
"::verify(char *fp, char *name)" because it can't be done w/BearSSL w/o
user code changes, and always failed. Better to have a compile failure
when we know at compile time the app won't do what is expected.
Completes the changes started by @d-a-v in PR #4833
Add a method allowing a user to send in a character string for the
fingerprint, like axTLS supported.
Implements part of PR #4833 from @d-a-v with changes requested in
discussion.
The BearSSL second stack, once allocated, was never deallocated. The
reference count of the stack pointer never hit 0 due to the initial
creation counting as one. Now, check to see if there is only one use_count
and if so then delete the stack.
SSL Sessions enable most of the SSL handshake to be skipped when both
client and server agree to use them. Add a BearSSLSession class and
an optional setting to the SSL client to enable this.
Note that SSL sessions are unrelated to HTTP sessions. They are
ephemeral and only relate to the SSL parameters, not anything at
the HTTP protocol level.
The cipher list count/pointer was cleared separately in the three
constructors available. Move this reset to _clear() to reduce code
duplication and keep the semantics.
Pull in latest BearSSL head (0.6 + minor additions) release and add AES_CCM
modes to the encryption options. Enable the aes_ccm initialization in client/server
The EC mul20 and square20 code was identical in two different files,
but because these copies were static, we ended up with an extra 6k of
duplicated code. Updated BearSSL to make them shared, saving 6KB.
