  1. Move crc32 implementation from storage/innodb to mysys 

    Prepares for common use of implementation of:
Bug#79155 optimized crc32 for CRC32() function
Bug#79325 optimized crc32 for binary log checksums

  2. Add common text description of crc32 for logging 

    Facilitates expansion of description for other optmised crc32 implementations:
Bug#74776    InnoDB checksums (new or crc32) use too much CPU on POWER8
Bug#79144    No hardware CRC32 implementation for AArch64

  3. Add POWER8 optimized crc32 code

  4. Hook power8 crc32 implementation in for linux ppc64le platform 

    This is only used on Linux where we detect (at runtime) that ARCH_2_07
is available (which has the necessary hardware instructions).

  5. Initialise crc32 globally 

    To facilitate:
Bug#79155 optimized crc32 for CRC32() function
Bug#79325 optimized crc32 for binary log checksums

  7. Replace binary_log::checksum_crc32 with optimized ut0crc32 version 

    This preserves the same api as zlib's crc32

*_ex(tended) crc32 functions added to handle incremental crc32 calculations.

Static initializer Log_event::_init LogEvent::_initializer; added to ensure
client programs that use LogEvent have crc32 initialized.

mysqlbinlog and mysqld's binlog code now uses optimized crc32 code rather than
zlib's.

Solves:
Bug#79325 optimized crc32 for binary log checksums
