    Add soft warning log line when using liberasurecode <1.3.1

    To apply the fix for a liberasurecode issue [1], we need hard depencency
    of liberasurecode requires >=1.3.1. However current binary dependency
    maintainance tool "bindep" works only for packagers' repository. (i.e. it
    refers the version of apt/yum/etc...) And nothing is cared for the binary
    built from source.

    This patch provides a way to detect incompatible liberasurecode and
    makes a warning log line to syslog which suggest "you're using older
    liberasurecode which will be deprecated, please upgrade it".

    NOTE:
    - This dependency managemnet depends on erasurecode_version.h header
      file in liberasurecode. i.e. it cannot care of overwritten .so library
      after PyECLib built once.
