WT-2873 Refactor CRC32 code (#3000)
* Add --enable-crc32-hardware configuration option (configured on by default), which allows CRC32 hardware support to be turned off.
* Move the CRC32 implementation in software from the x86-specific code to software/checksum.c, leave the x86-specific code in x86/crc32-x86.c.
* Move the pointer to the checksum function from a file static to the WT_PROCESS.cksum field, change the __wt_cksum_init() function to set that field.
* WT-2882 Create CRC32 Hardware implementation for ARM8
* Change "cksum" to "checksum" everywhere (hopefully) no semantic changes.
