It is also updated to support knot105 format,
also Makefile is included see tests/chkjournal.c header
for more info.

It is able to compile both current, 32/64bit specific versions,
but requires libknotd.la compiled with respective flag.

Implemented as a first uint32_t before serialized
RR sets in journal. Currently available:
1 << 0 .. IXFR
1 << 1 .. UPDATE

Backward-incompatible change in journal, bumping journal

refs #1130

Implemented as a XFR handler task, in a same way as NOTIFY queries
for example. It also allows to change TSIG keys between hops,
or no keys at all - this clear AD flag.
Like: client <--key:A--> f1 <--key:B--> f2 <--NOKEY--> MASTER
Forwarded queries also keep socket mode.

To do:
According to RFC2845, it should also forward queries with no
known key intact to the next forwarded, this is not done yet.
