gdbstub: Replace strcpy() by strscpy()
The strcpy() function is being deprecated. Replace it by the safer strscpy() and fix the following Coverity warning: "You might overrun the 1024-character fixed-size string remcom_in_buffer by copying cmd without checking the length." Addresses-Coverity-ID: 138999 ("Copy into fixed size buffer") Signed-off-by: Gustavo A. R. Silva <gustavo@embeddedor.com> Signed-off-by: Daniel Thompson <daniel.thompson@linaro.org>
