323db6d08d Default timeout parameter added 
When we're modifying the binary format, we can introduce host-dependent
timeouts as well.

bd5caae1ee Introduce new host_flags field 
While we're at it with migration, might as well add a host_flags field
so that if we have host-specific configuration flags we want to add
later on, we only have to do a migration once.

af29d9cbf8 Preliminary file migration 
Pretty raw and untested code which migrates data from v2 to v3,
introducing a new field in the process. This field is neither editable
as of now nor is it honored if it were set.

b0909557ad Refactoring of version code 
We want to introduce a new feature (volumes with discard support) which
will cause file incompatibility.  This means we need to prepare data
migration code. This prepares that change.

47f7ca6c31 Fix numerous log format issues 
We had not declared function attributes that check the format syntax;
this led to a number of issues that remained undetected. Fixed.

dce9c1b323 Vaulted keydb should work, but it's not used yet 
All the methods are implemented to get the vaulted key database running,
but it's not in use yet.

849e3a5949 Implemented finding of keyserver and unlocking of volumes 
We'll now parse the response messages on the client side, abort after a
previously defined timeout and trigger the LUKS unlocking process, if
requested (although the latter isn't fully implemented yet).

0e8e42d0ea Client and server commnunication now works 
We can send our little datagrams over and that works nicely. Need to
consolidate the PSK session establishment into one shared function.

603e63876f Server implementation seems to work 
Rudimentary functionality of server (not including responding to
announcements over UDP) is working now.

3e5c7d541c Implement actual lookup of luksrku entry 
Now with a proper UUID the PSK is looked up from the key database.

20ffe38b53 Implemented export of key database 
Key database is exported on a client-per-client basis, but with
sanitized LUKS passphrases of course. This is implemented now.

722476e7fd Implemented more useful commands 
Implemented add/delete operations of hosts and volumes and rekeying of
both as well.

0cb0e5d470 Further work in keydb 
Work in transcribing the binary LUKS PSK to ASCII. Still buggy, had an
error in thinking (it's not 4 bytes transcribed to 3, but 3 to 4 of
course). Needs fixing.

bcd794a6c1 Further work on creating correct type-4 UUIDs 
Have the UUIDs actually look and feel like Type-4 UUIDs according to
RFC.

ffca14559f Further work on UUIDs and the interactive editor 
Listing now works and we've extracted the UUID code into separate files.

68c74de050 Saving and loading of key database works 
We now can save and load the database from a file and also add hosts.

9c888cbe4e Major rework of keydb and file encryption 
Currently, main program does not compile, massive rework of the internal
database storage mechanism to allow integration of vault and online
editing.
