Fix a crash in String::changeBuffer()

d891704c1e Reduce stack usage by Print::printf 
Print::printf would allocate 1460 bytes on the stack, which in some cases would overflow the stack. Additionally it didn't handle (rare) cases when vsnprintf needed a buffer longer than 1460 bytes. This change makes default stack-allocated buffer 64 bytes long, and checks the result returned by vsnprintf. If a buffer longer than 64 bytes is needed, it is allocated on the heap.

fdf8599aaa Fix a crash in String::changeBuffer() 
Calling String::reserve() causes a crash if String object was in invalidated state. Per the comment on the method's declaration in ESP_SSD1306.h, This method was supposed to recover invalidated strings. This change fixes the edge case bug in String::changeBuffer() which is the root cause of the crash exposed from String::reserve().

Following test code was used to reproduce the problem and also to validate the fix:

String result;
while(true){
  char c = 'A';
  result += c; // the loop will cause malloc() to fail at some point.
  if (result.c_str()==0)
  {
    Serial.println("String INVALIDATED!!!!!");
    result.reserve(0);   // before fix, this would crash.
    Serial.println("Trying to empty....");
    result=""; 
    Serial.println("Emptied!!!!");
    break;
  } 
}

e3bf9bb1e8 Added bit mask and constant for SerialConfig parameter 
Permit use bit config avoiding test/compare all "hard-coded" values.
example
```arduino
if (section & CFG_HLP_MODBUS) {
DebuglnF("\r\n===== Modbus");
DebugF("Speed       : "); Debug(config.modbus.baud);

switch (config.modbus.proto & UART_NB_BIT_MASK) {
case UART_NB_BIT_5: Debug(" 5"); break;
case UART_NB_BIT_6: Debug(" 6"); break;
case UART_NB_BIT_7: Debug(" 7"); break;
case UART_NB_BIT_8: Debug(" 8"); break;
default : Debug(" ?"); break;
}
switch (config.modbus.proto & UART_PARITY_MASK) {
case UART_PARITY_NONE: Debug("N"); break;
case UART_PARITY_EVEN: Debug("E"); break;
case UART_PARITY_ODD : Debug("O"); break;
default : Debug("?"); break;
}
switch (config.modbus.proto & UART_NB_STOP_BIT_MASK) {
case UART_NB_STOP_BIT_0: Debug("0"); break;
case UART_NB_STOP_BIT_1: Debug("1"); break;
case UART_NB_STOP_BIT_15: Debug("15"); break;
case UART_NB_STOP_BIT_2 : Debug("2"); break;
default : Debug("?"); break;
}

DebugF("\r\nSlave Addr  : "); Debugln(config.modbus.slave);
DebugF("Holding Reg : 0x"); Debugln2(config.modbus.hr_addr,HEX);
DebugF("Enable Pin  : "); Debugln(config.modbus.en_pin);
}
```

737f6c28ea Remove forced alignment in operators new and delete 
This alignment prevents umm_malloc to detect buffer overruns which fall within padding introduced by new/new[]. Allocated memory will be aligned by design of umm_malloc, so we don't need to pad anything here.
Also fixed some formatting/newlines and removed unused header files.
