  debugV("* Run time: %02u:%02u:%02u (VERBOSE)", mRunHours, mRunMinutes, mRunSeconds);
    (V p:3065 loop C1) * Run time: 00:41:23 (VERBOSE)

    Where:  V: is the level
            p: is a profiler time, elased, between this and previous debug
            loop: is a function name, that executed this debug
            C1: is a core that executed this debug (and a function of this) (only for ESP32)
            The remaining is the message formatted (printf)
For release your device, just uncomment DEBUG_DISABLED in your project
Done this, and no more debug processing.
And better for DEBUG_DISABLED, __RemoteDebug__ have ZERO overhead,
due is nothing of this is compiled.
- An app to RemoteDebug like SerialDebug have.
- Http page to begin/stop the telnet server or websocket server.
- Authentication as telnet support (kerberos, etc.) to support production environment
#include "RemoteDebug.h"  //https://github.com/JoaoLopesF/RemoteDebug
// Initialize the server (telnet or web socket) of RemoteDebug

Debug.begin(HOST_NAME);

// OR

Debug.begin(HOST_NAME, startingDebugLevel);

// Options

Debug.setResetCmdEnabled(true); // Enable the reset command

// Debug.showProfiler(true); // To show profiler - time between messages of Debug

// Remote debug over WiFi

Debug.handle();

// Or

debugHandle(); // Equal to SerialDebug

It will show in client (telnet or web app):

    (V p:^0000ms) (foo)(C1) this is a debug - var 1

Where:

    V -> verbose
    p -> profiler time
    (foo) -> this is a function name that calls the debug macro
    (C1) -> It is running it Core 1 (only for ESP32)
Useful to see messages if setup or
in cause the ESP8266/ESP32 is rebooting (client connection stop before received all messages)
Only for this purposes I suggest it
// Setup after Debug.begin

Debug.setSerialEnabled(true); // All messages too send to serial too, and can be see in serial monitor
- Please press enter or any key if you need keep the connection
- The default is 5 minutes (You can change it in RemoteDebug.h)
- You can use mDNS to register each node with different name, it helps to connect without know the IP.
---> This is very important to reduce overheads and work of debug levels
- Ajustment on debugA macro, thanks @jetpax and @cmidgley to add this issue.
- All public configurations (#defines) have moved to RemoteDebugCfg.h, to facilitate changes for anybody.
- Changed examples, with warnings on change any #define in project,
  with workarounds if it not work. (thanks to @22MarioZ for added this issue)
- Adjustments if web socket is disabled
- Adjustments in examples, added one for debugger
- Adjustments in silente mode
- Commands from RemoteDebugApp now is treated
- Adjusts to RemoteDebugger support connection by web sockets
- If not disabled, add a web socket server to comunicate with RemoteDebugApp (HTML5 web app)
- The standard telnet still working, to debug with internet offline
- Ajustment on debugA macro, thanks @jetpax to add this issue
- Add empty rprint* macros, if debug is disabled
- Create option DEBUG_DISABLE_AUTO_FUNC
- Create macros to be used for code converter: rprint and rprintln
  RemoteDebug now have an code converters to help migrate codes
- Create precompiler DEBUG_DISABLED to compile for production/release,
  equal that have in SerialDebug
- Adjustments in examples
- Adjustments for the debugger: it still disable until dbg command, equal to SerialDebug
- The callback will to be called before print debug messages now
- And only if debugger is enabled in RemoteDebugger (command dbg)
-  Changed handle debugger logic
- Added support to RemoteDebug addon library: the RemoteDebugger, an simple software debugger, based on SerialDebug
- New color system
- Bug -> sometimes the command is process twice
- Workaround -> check time
- New macros to compatibility with SerialDebug (can use RemoteDebug or SerialDebug) thanks to @phrxmd
- Fixed bug for MAX_TIME_INACTIVE, thanks to @achuchev to add this issue
- Adjustments based on pull request from @jeroenst (to allow serial output with telnet password and setPassword method)
- Serial output is now not allowed if telnet password is enabled
- Few adjustments
- Few adjustment in write logic
- Serial output adjustments (due bug in password logic)
- Correct rdebug macro (thanks @stritti)
- New silent mode (command s)
- Auto function name and ESP32 core id for rdebug* macros
- begin method have a option for port number
- Few adjustments
- Added new rdebug?ln to put auto new line
- Simple text password request feature (disabled by default)

    Notes:
      It is very simple feature, only text, no cryptography,
      and the password is echoed in screen (I not discovery yet how disable it)

      telnet use advanced authentication (kerberos, etc.)
      Such as now RemoteDebug is not for production (releases),
      this kind of authentication will not be done now.
- Adjustments in precompiler macros
- Bug in write with latest ESP8266 SDK
- Port number can be modified in project Arduino (.ino file)
-  Few adjustments as ESP32 includes
- Adjustments, as avoid ESP32 include errors
- Telnet port of server can be modified by project
  Just put it in your .ino, before the include:
- Shortcuts and client buffering to avoid mysterious delay of ESP networking
- Adjustments and now runs in Esp32 too.
- Adjustments and improvements from Beta versions.

  New features:

    - Filter
    - Colors
    - Support to Windows telnet client
- First Beta
- Sometimes (rarely) the connection over telnet becomes very slow.
  Especially right after uploading firmware.
  Reset command in telnet connection or turn off/on can be resolve it.
  But I need find why it occurs
First thanks a lot for Igrr for bring to us the Arduino ESP8266 and to Espressif to Arduino ESP32

Thanks to Links2004 for a good web server socket, used for web app connection.
