60dcbecf04 Instead of choosing between memcpy and memmove at run time, call 
memmove unconditionally since any reasonable implementation of
memmove will perform such a choice internally, and also doing it
in the caller duplicates the effort.

0c264c9094 The prefix and suffix names used in name compression don't need offset tables, 
since they're never used.  Not having offset tables makes filling in their

575737b964 Rewrite the name compression code to use a hashtable instead of an RBT and 
avoid allocating memory in most cases.  This increases performance by
about 225% on the rc query test (~305 q/s to 990 q/s).

e28b5084ec Bitstring labels *still* suck. They didn't somehow magically get less 
sucky in the past couple of months.  The nerve.

Anyway, dns_name_split now correctly compacts the preceding bitstring label
(if any) when a maximal bitstring is split.

It also correctly creates the suffix when a maximal bitstring is split.
It was doing this incorrectly before, independent of the compaction issue.

72ce8db918 sigh. the last checkin only included RT #369 fix, not the other things I meant

190fbe9738 519. [bug] dns_name_split() would improperly split some bitstring 
labels, zeroing a few of the least signficant bits in
			the prefix part.  When such an improperly created
			prefix was returned to the RBT database, the bogus
			label was dutifully stored, corrupting the tree.
			[RT #369]

Also made dns_name_split() REQUIRE that suffixlabels always be greater than 0,
even when splitting a bitstring label (it already required this when not
splitting a bitstring label).  This is consistent with the way dns_name_split()
was called to split a name that consisted of a single label, a bitstring;
the appropriate suffixlabels value is 1 in such cases.

Also a fixed minor style error, and a confusing comment.

dc570b92f6 Add support for proposed ZONE and VIEW opt attributes. These are currently 
hidden behind #ifdef's, since no OPT code number has yet to be assigned
by the IANA.  They are also not quite complete in all regards; VIEW
options are understood and ignored.  ZONE options are understood and
acted upon, though some of the error cases aren't quite right.

Remove doubled isc_mem_stats in dighost.c

Update todo list.

Change literal 255's to DNS_NAME_MAXWIRE in name.c

f3b52d9fe5 If an uncompressed name will take more than 255 characters and the buffer is 
sufficiently long, dns_name_fromwire should return DNS_R_FORMERR, not
ISC_R_NOSPACE.
