Mac functions - strlcpy and strlcat

Some functions aren't defined in Linux

• strlcpy and strlcat
• mach_absolute_time
• host_info
• NXGetAllArchInfos
• CFStringGetLength
• Cocoa

Easy to implement by myself

  size_t strlcpy(char* dst, const char* src, size_t size) {
    dst[size - 1] = '\0';
    strncpy(dst, src, size - 1);
    return strlen(dst);
  }
