finsh: replace str/mem functions with rt-prefixed versions

illustriousness · Rbb666 · commit 29fb860ad43f · 2025-11-22T09:31:37.000+08:00
Replace standard string and memory functions with RT-Thread's rt-prefixed
equivalents where available:

- strcpy -&gt; rt_strcpy
- strncpy -&gt; rt_strncpy
- strcmp -&gt; rt_strcmp
- strncmp -&gt; rt_strncmp
- strlen -&gt; rt_strlen
- strstr -&gt; rt_strstr
- memcpy -&gt; rt_memcpy
- memcmp -&gt; rt_memcmp

Functions like strcat, strchr remain unchanged as RT-Thread does not provide
rt-prefixed versions.
