dev-libs/isa-l: initial import

Required by erasure-coding features of net-libs/xrootd - or rather WILL
BE required, as at the moment the latter seems to have no option to use
a system-installed version.

+	ISA-L is a collection of optimized low-level functions targeting storage applications. ISA-L includes:
+	* Erasure codes - Fast block Reed-Solomon type erasure codes for any encode/decode matrix in GF(2^8).
+	* CRC - Fast implementations of cyclic redundancy check. Six different polynomials supported.
+		* iscsi32, ieee32, t10dif, ecma64, iso64, jones64.
+	* Raid - calculate and operate on XOR and P+Q parity found in common RAID implementations.
+	* Compression - Fast deflate-compatible data compression.
+	* De-compression - Fast inflate-compatible data compression.
+	* igzip - A command line application like gzip, accelerated with ISA-L.
