    lib: fix warnings found when porting to NuttX
    
    - Undefine DEBUGASSERT in curl_setup_once.h in case it was already
      defined as a system macro.
    
    - Don't compile write32_le in curl_endian unless
      CURL_SIZEOF_CURL_OFF_T > 4, since it's only used by Curl_write64_le.
    
    - Include <arpa/inet.h> in socketpair.c.
    
    Closes https://github.com/curl/curl/pull/4756
