problem reported with the obvious fix for bgpd by Sebastian Benoit

applied to all the others by yours truly. ok theo
isn't it amazing how far this parser (and more) spread?
it with a simple filter in the yylex() loop.
The compression in lgetc() didn't happen for quoted strings,
thus creating a regression when tabs were used in variables.
Some testing by todd@ and pyr@

expand to space or tab, and a \ followed by newline should be ignored
(as a line continuation). compatible with the needs of hoststated
(which has the most strict quoted string requirements), and ifstated
(where one commonly does line continuations in strings).
pointed out by mpf, discussed with pyr
yylex implementation and the code which interacts with yylex. this also
brings the future potential for include support to all of the parsers.
in the future please do not silly modifications to one of these files
without checking if you are de-unifying the code.
checked by developers in all these areas.
as found in hoststated, and make all the code diff as clean as possible. a
few issues remain mostly surrounding include support, which will likely be
added to more of the grammers soon.
ok norby pyr, others
negative parameters. extend lex to spot numbers in the stream. as well,
make it easier to add parameters on command line in any order later

looping over the addresses returned by the dns lookup, as each address
is one new peer.
however, if the lookup fails with a temporary error, we will try to lookup
later again. for that, we obviously need to insert one peer with the
hostname in addr_head... change one for() loop into a do { } while() one
to resolve the hostname every 60 seconds
fixes ntpd invocations before e. g. a dialup link is established and such.
as we want ntpd to be a "fire and forget" background daemon it should
cope with such situations.
tested by many
which, besides the head pointer for the list of course, stores the original
address as specified (i. e. as hostname instead of resolved IPs) and flags
and such.
we know have both a "server" and "servers" keyword. they differ when the
hostname resolves to more than one IP, server picks one and servers expands
to all.
that means no longer stuffing a sockaddr_storage into ntp_peer but a pointer
to a linked list of ntp_addr structs.
in the "servers" case the list of n addresses returned by host() is expanded
into n ntp_peer structs and thus n individual peers.
in the "server" case the whole list is attached to ntp_peer, and whenever we
do not receive a reply in time we traverse the list one further, so that
hosts with both AAAA and A records are first tried with the AAAA one but
we gracefully fall back to the A one.
semantics with theo; hacked up on the Montreal->Frankfurt flight.
again Air Canada surprised me, that older 767 hat pretty decent seats.
fixes the dns resolves to v4 and v6 addresses bug found by phessler
hacked on the Calgary->Montreal flight that proved that Air Canada _does_
have some modern aircrafts with good seats
struct ntp_addr, which just wraps a sockaddr_storage and a next pointer,
so that host_dns can return more than one entry.
let host_dns do exactly that, return a list of all IPs for that hostname
adjust all callers in the grammar to cope with that
hook the descriptors into the main poll and such.
we're not doing anything with the reply we recive yet, tho.
mostly hacked on the Frankfurt->Montreal flight, as batteries and those
horrible air canada seats permitted...
