Detailed Description

IRDA Transmit and Receive functions.

  ==============================================================================
                      ##### IO operation functions #####
  ==============================================================================
    [..]
    This subsection provides a set of functions allowing to manage the IRDA data transfers.
    IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
    on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver
    is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
    While receiving data, transmission should be avoided as the data to be transmitted
    could be corrupted.

    (#) There are two modes of transfer:
       (++) Blocking mode: The communication is performed in polling mode.
            The HAL status of all data processing is returned by the same function
            after finishing transfer.
       (++) Non-Blocking mode: The communication is performed using Interrupts
           or DMA, these API's return the HAL status.
           The end of the data processing will be indicated through the
           dedicated IRDA IRQ when using Interrupt mode or the DMA IRQ when
           using DMA mode.
           The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
           will be executed respectively at the end of the Transmit or Receive process
           The HAL_IRDA_ErrorCallback() user callback will be executed when a communication error is detected

    (#) Blocking mode APIs are :
        (++) HAL_IRDA_Transmit()
        (++) HAL_IRDA_Receive()

    (#) Non Blocking mode APIs with Interrupt are :
        (++) HAL_IRDA_Transmit_IT()
        (++) HAL_IRDA_Receive_IT()
        (++) HAL_IRDA_IRQHandler()

    (#) Non Blocking mode functions with DMA are :
        (++) HAL_IRDA_Transmit_DMA()
        (++) HAL_IRDA_Receive_DMA()
        (++) HAL_IRDA_DMAPause()
        (++) HAL_IRDA_DMAResume()
        (++) HAL_IRDA_DMAStop()

    (#) A set of Transfer Complete Callbacks are provided in Non Blocking mode:
        (++) HAL_IRDA_TxHalfCpltCallback()
        (++) HAL_IRDA_TxCpltCallback()
        (++) HAL_IRDA_RxHalfCpltCallback()
        (++) HAL_IRDA_RxCpltCallback()
        (++) HAL_IRDA_ErrorCallback()

    (#) Non-Blocking mode transfers could be aborted using Abort API's :
        (+) HAL_IRDA_Abort()
        (+) HAL_IRDA_AbortTransmit()
        (+) HAL_IRDA_AbortReceive()
        (+) HAL_IRDA_Abort_IT()
        (+) HAL_IRDA_AbortTransmit_IT()
        (+) HAL_IRDA_AbortReceive_IT()

    (#) For Abort services based on interrupts (HAL_IRDA_Abortxxx_IT), a set of Abort Complete Callbacks are provided:
        (+) HAL_IRDA_AbortCpltCallback()
        (+) HAL_IRDA_AbortTransmitCpltCallback()
        (+) HAL_IRDA_AbortReceiveCpltCallback()

    (#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
        Errors are handled as follows :
        (+) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is
            to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error in Interrupt mode reception .
            Received character is then retrieved and stored in Rx buffer, Error code is set to allow user to identify error type,
            and HAL_IRDA_ErrorCallback() user callback is executed. Transfer is kept ongoing on IRDA side.
            If user wants to abort it, Abort services should be called by user.
        (+) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
            This concerns Overrun Error In Interrupt mode reception and all errors in DMA mode.
            Error code is set to allow user to identify error type, and HAL_IRDA_ErrorCallback() user callback is executed.
