illumos gate

No functional changes; move current loader libcrypto sources and build into libstand. This is needed because future crypto implementation bits need to access libstand, but .a archives are limited in cross linking. This is also the reason why zfs reader code is in libstand.

While there, move crypto bits from libstand/zfs into libstand/crypto.

Testing done: build/install/boot

wsdiff. I did run wsdiff to compare master and 13785; the expected changes are linked binaries (symbol address changes), .make.state files, softcore.c (generated file with timestamp) and Makefiles.

wsdiff -vr report.txt boot /tmp/boot
