Dmytro Bagrii 77b4714604 examples: server: Fix const qualifier discard
Compiling with gcc-16.1.1 and glibc-2.43 yields warnings: "initialization
discards ‘const’ qualifier from pointer target type".

Indeed, pointer passed to strchr() is `const char *` and memory pointed by
return value of strchr() is never modified, so variable to assign return
value should be `const char *`.

Jon Shallow 46e505c430 OSCORE: Support using MbedTLS for OSCORE only (not (D)TLS)
New ./configure option

 --with-mbedtls-oscore

If --disable-dtls is set, then MbedTLS is used as the OSCORE backend, otherwise
the MbedTLS library is used for both (D)TLS and OSCORE.

New cmake option

 -DOSCORE_BACKEND=mbedtls

If -DENABLE_DTLS=OFF is set, then MbedTLS is used as the OSCORE backend, otherwise
the MbedTLS library is used for both (D)TLS and OSCORE.

New Zephyr option

 config MBEDTLS_OSCORE

If set to y and CONFIG_LIBCOAP_OSCORE_SUPPORT is set to y, then the Zephyr MbedTLS
backend will get used for the OSCORE backend (no (D)TLS).

lwipopts.h and there is a suitable

make use of the defined pools.

A new src/coap_mem_lwip.c file has been added.

Lucien Zuercher 855d53ef10 oscore: enable external credential storage and safe recipient cleanup
Add reference counting to recipient contexts so they can be safely removed
while still in use by active sessions. Expose callback hooks for credential
lookup, echo, and sequence storage to allow custom backends.
Expand example server to demonstrate the external storage via a simple
file based database. Expand coap_oscore_rcp_conf_t to enable settings
preconfigured echo value, sequence counter and window value as uint64
Enable temporary credentials returned by the find function and are destroyed
after use.
