And in onException frame there is:
(gdb) p ((DB::Exception *)exception._M_exception_object)._msg._M_dataplus._M_p
$6 = (...) 0x7f0c9b1e7a40 "Unknown packet 9 from server HOSTNAME:PORT"
And on "Unknown packet" there is disconnect() before, see default in
switch statement at Connection::receivePacket().

This extras includes:
- server revision
- query settings
- query
Otherwise the code can try to interpret data, and got for instance
std::length_error exception, which is not catched (to mark the part as
broken). Also this will protect from the corruptions on disk.
And add a simple test, since dbms/tests/integration/test_insert_into_distributed too complex.
Also simplify the code by using readStringBinary() over
readVarUInt()+b.readStrict() (this also gains additional checks that
string is not bigger then 1GB).
Refs: #4852 (8ef7f3589a)
v2: avoid ABI breakage (suggested by @vitlibar)
v3: minor code fixes (suggested by @vitlibar) and as a consequence clang-8 build fix
v4: drop DBMS_MIN_REVISION_WITH_EXTRAS_CHECKSUM_IN_DIST_BATCH and also
revert some renames to make the patch cleaner
