5c6df49067 Switch to AES-256 
AES-256 seems to be becoming the industry standard. While AES-128 is
good enough for tens of years to come, let's follow suit and be extra
safe.

e6b7353f4e Switch nonce generation to purely random 
The old implementation of counting up from a random starting
point had the problem that is allowed an attacker to find out
the write order of the blocks.

aa082c235a Utimens: Use UtimesNano instead of Futimes 
Futimes() only takes microsecond resolution while the FUSE call
Utimens() wants nanosecond precision.

This is why UTIME_OMIT did not work - this change fixes the
xfstests generic/258 test failure.

The go library does not provide a FutimesNano() function which is
why I use UtimesNano() on /proc/self/fd/n.
This is what the Go library does in Futimes().

90bd978283 truncate: Fix bug that caused xfstests generic/030 to fail

have been used.
Renamed the symbols for less confusion.

c859f0b2dc intraBlock: Rename Offset to Skip 
"Offset" is unclear whether it is an offset from the start of file
or start of block. "Skip" seems much better.
