DTO API

DTO provides drop-in replacements for standard memory operations. Each function
is available in three forms:

• *_default uses library defaults.
• *_cfg accepts a struct dto_call_cfg to override per-call behavior.
• The unsuffixed name derives configuration from a bitwise OR of DTO_API_*
  flags.

Sample usage

/* Use defaults */
dto_memcpy_default(dst, src, sizeof(src));

/* Per-call configuration */
struct dto_call_cfg cfg = {
    .auto_adjust = 0,
    .cache_control = 1,
    .wait_method = WAIT_BUSYPOLL,
    .numa_mode = NA_BUFFER_CENTRIC,
    .overlapping_action = OVERLAPPING_CPU,
};
int diff = dto_memcmp_cfg(dst, src, sizeof(src), &cfg);

/* Flags-based configuration */
dto_memset(dst, 0, sizeof(dst), DTO_API_WAIT_YIELD);
