Bug 1089681: xtrabackup export - support tables with more than 31 ind…
Added option decrypt for xbstream
Blueprint: <https://blueprints.launchpad.net/percona-xtrabackup/+spec/use-hw-crc32> xtrabackup is using CRC32 in two places: - when producing and reading xbstream format - when producing and reading xbcrypt format Since both places are pure xtrabackup, this patch simply replaces invocation of `crc32` with `crc32_iso3309` without touching server code. `crc32_iso3309` invokes hardware optimized CRC32 implementation taken from `libgrypt` when `PCLMUL` instruction is available. When `PCLMUL` isn't available, it falls back to software CRC32 from Zlib.
