mg_hexdump()	mg_hexdump	func	int mg_hexdump(const void *buf, int len, char *dst, int dst_len);

Generates a human-readable hexdump of memory chunk.

Takes a memory buffer buf of length len and creates a hex dump of that buffer in dst. The generated output is a-la hexdump(1). Returns the length of generated string, excluding terminating \0. If returned length is bigger than dst_len, the overflow bytes are discarded.
