Log Message:
Update to 1.0.36:

1. SECURITY FIX: When constructing paths of objects being archived, a buffer
could overflow by one byte upon encountering 1024, 2048, 4096, etc. byte
paths. Theoretically this could be exploited by an unprivileged user whose
files are being archived; I do not believe it is exploitable in practice,
but I am offering a $1000 bounty for the first person who can prove me wrong:

2. SECURITY FIX: An attacker with a machine's write keys, or with read keys
and control of the tarsnap service, could make tarsnap allocate a large
amount of memory upon listing archives or reading an archive the attacker
created; on 32-bit machines, tarsnap can be caused to crash under the
aforementioned conditions.

3. BUG FIX: Tarsnap no longer crashes if its first DNS lookup fails.

4. BUG FIX: Tarsnap no longer exits with "Callbacks uninitialized" when
running on a dual-stack network if the first IP stack it attempts fails to
connect.

5. tarsnap now avoids opening devices nodes on linux if it is instructed to
archive /dev/.  This change may prevent "watchdog"-triggered reboots.

6. tarsnap -c --dry-run can now run without a keyfile, allowing users to
predict how much Tarsnap will cost before signing up.

7. tarsnap now has bash completion scripts.

8. tarsnap now takes a --retry-forever option.

9. tarsnap now automatically detects and uses AESNI and SSE2.

As usual, there are also many minor build fixes, harmless bug fixes, and code
refactoring / cleanup changes.  For a full listing of changes, consult the
