What changed in this PR

Removes the legacy Contiki/uIP integration from wolfSSL, including socket callbacks and platform-specific configuration. Builds using either removed feature macro now receive an explicit error.

Changes:

• Remove uIP transport callbacks, context types, and callback registration.
• Remove Contiki-specific configuration, header exceptions, and random-seed handling.
• Reject WOLFSSL_CONTIKI and WOLFSSL_UIP, while retaining macro-check recognition for WOLFSSL_UIP.

File	Description
wolfssl/​wolfio.h	Remove uIP context and callback declarations and Contiki I/O exceptions.
wolfssl/​wolfcrypt/​settings.h	Replace Contiki configuration with an explicit removal error.
wolfssl/​ssl.h	Remove the Contiki exception for including sys/uio.h.
wolfcrypt/​src/​random.c	Remove Contiki from platform-specific seed handling.
src/​wolfio.c	Remove uIP transport and cookie callbacks and the Contiki header exception.
src/​internal.c	Remove automatic uIP callback registration.
.wolfssl_known_macro_extras	Add WOLFSSL_UIP to the known-macro list.
