There was a single fpu context shared per session, if multiple threads were using the session, and both migrated away, they could corrupt each other's fpu context... This patch adds a per cpu context and a lock to protect it... It also tries to better address unloading of the aesni module... The pause will be removed once the OpenCrypto Framework provides a better method for draining callers into _newsession... I first discovered the fpu context sharing issue w/ a flood ping over an IPsec tunnel between two bhyve machines... The patch in D3015 was used to verify that this fix does fix the issue...
