contentenc: fix CipherSizeToPlainSize non-monoticity
...
For an illegal cipherSize, pretend we have an additional
1-byte block.
See code comment for details.

contentenc: catch integer underflow in file size calculation
...
If you truncate a ciphertext file to 19 bytes, you could get the
impression that the plaintext is 18446744073709551585 bytes long,
as reported by "ls -l".
Fix it by clamping the value to zero.

fusefrontend: coalesce grows in Truncate()
...
We were growing the file block-by-block which was pretty
inefficient. We now coalesce all the grows into a single
Ftruncate. Also simplifies the code!
Simplistic benchmark: Before:
$ time truncate -s 1000M foo
real 0m0.568s
After:
$ time truncate -s 1000M foo
real 0m0.205s

Rename internal "toggledlog" package to "tlog"
...
tlog is used heavily everywhere and deserves a shorter name.
Renamed using sed magic, without any manual rework:
find * -type f -exec sed -i 's/toggledlog/tlog/g' {} +
