A conversation in Wireshark might have two endpoints or might have no
endpoints; few if any have one endpoint. Distinguish between
conversations and endpoints.
Allocate the root node in the same pool as the list itself, and make
that pool explicit so we can pass the pinfo scope instead of using the
global packet pool.
We prefer pinfo->pool over the global wmem_packet_scope() now. Convert a
few more asn1 dissectors. After this commit, just three asn1 dissectors
remain.
Part 1/2 as the commits were too big for CI.
Largely find/replace, with a few manual tweaks. Then regenerate the asn1
dissector sources and make sure everything still builds. There are a
handful of cases I skipped as too complex, but this covers most of the
asn1 dissectors.
Most of the time, the return value tells us nothing useful, as we've
already decided that we're perfectly willing to live with string
truncation. Hopefully this keeps Coverity from whining that those
routines could return an error code (NARRATOR: They don't) and thus that
we're ignoring the possibility of failure (as indicated, we've already
decided that we can live with string truncation, so truncation is *NOT*
a failure).
Make the time stamp precision a 4-bit bitfield, so, when combined with
the other bitfields, we have 32 bits. That means we put the flags at
the same structure level as the time stamp precision, so they can be
combined; that gets rid of an extra "flags." for references to the flags.
Put the two pointers next to each other, and after a multiple of 8 bytes
worth of other fields, so that there's no padding before or between them.
It's still not down to 64 bytes, which is the next lower power of 2, so
there's more work to do.

Some of the ASN.1 dissectors process their data indirectly through
dissector tables. Add dissector_try_string_new so that they can do so
without appending duplicate entries to frame.protocols.

For the moment this mirrors the port_type enumeration (PT_XXX), but the
intent is to move away from using "port types", eliminating most (if not
all)
Added conversation_pt_to_endpoint_type() so that conversations deal with the
correct enumeration. This is for dissector that use pinfo->ptype as input
to conversation APIs. Explicit use of port types are converted to using
ENDPOINT_XXX type.

This emphasizes that there is no such thing as *the* routine to
construct a subset tvbuff; you need to choose one of
tvb_new_subset_remaining() (if you want a new tvbuff that contains
everything past a certain point in an existing tvbuff),
tvb_new_subset_length() (if you want a subset that contains everything
past a certain point, for some number of bytes, in an existing tvbuff),
and tvb_new_subset_length_caplen() (for all other cases).
Many of the calls to tvb_new_subset_length_caplen() should really be
calling one of the other routines; that's the next step. (This also
makes it easier to find the calls that need fixing.)

Those are the only ones meaningful. Let's convert the buggy dissectors
and add an assert to avoid the misuse of the pool parameter in the future

That doesn't work - you could be writing into the string from which
