This is to avoid ambiguity between compressed hex notation and
module namespacing, both which use "::". E.g.: "aaaa::bbbb" could
be an identifier or an IPv6 address, but "[aaaa::bbbb]" is now
clearly the address.
Also added IPv6 mixed notation to allow an IPv4 dotted-decimal
address to be specified in the lower 32-bits.
Internally, all BROv6 preprocessor switches were removed and
addr/subnet representations wrapped in the new IPAddr/IPPrefix classes.
Some script-layer changes of note:
- dns_AAAA_reply event signature changed: the string representation
of an IPv6 addr is easily derived from the addr value, it doesn't
need to be another parameter. This event also now generated directly
by the DNS analyzer instead of being "faked" into a dns_A_reply event.
- removed addr_to_count BIF. It used to return the host-order
count representation of IPv4 addresses only. To make it more
generic, we might later add a BIF to return a vector of counts
in order to support IPv6.
- changed the result of enclosing addr variables in vertical pipes
(e.g. |my_addr|) to return the bit-width of the address type which
is 128 for IPv6 and 32 for IPv4. It used to function the same
way as addr_to_count mentioned above.
- remove bro_has_ipv6 BIF

Includes:
- Updated baselines for autodoc tests.
- Now excluding stats.bro from external texts, it's not stable.
- Added a field named $last_alert to the SSL log. This doesn't even
indicate the direction the alert was sent, but we need to start somewhere.
- The x509_certificate function has an is_orig field now instead of
is_server and it's position in the argument list has moved.
- A bit of reorganization and cleanup in the core analyzer.
- Answers and TTLs are now vectors.
- The warning that was being generated (dns_reply_seen_after_done)
from transaction ID reuse is fixed.
- Updated the single failing btest baseline.
* origin/fastpath:
Binary packaging script tweaks.
More default "weird" tuning for the "SYN_with_data" notice.
Tiny bugfix for http file extraction along with test.
* origin/topic/jsiwek/http-1xx-replies:
Change logging of HTTP 1xx responses to occur in their own columns.
Fix handling of HTTP 1xx response codes (addresses #411).
- A null value no longer fits since if there is no body
a value of zero makes sense. Previously, a null value would
makes sense because the Content-Length header may not have
been sent which would leave the field null.
