Add mbedtls_test_ prefix to rnd_buf_info and
rnd_pseudo_info types, to rnd_std_rand(),
rnd_zero_rand(), rnd_buffer_rand() and
rnd_pseudo_rand() functions.
Command to change *.function files:
find . -name "*.function" -exec awk -i inplace \
'{sub(/rnd_(buf_info|pseudo_info|std_rand| \
zero_rand|buffer_rand|pseudo_rand)/, \
"mbedtls_test_&")}1' {} \;
