We may or may not be working on the currently-selected packet, so
there's no reason to use read into the capture_file's wtap_rec and
Buffer for the currently-selected packet. We already have a wtap_rec of
our own, and we currently have a pointer to a raw packet data array that
we can replace with a Buffer of our own; just read into them.
Use wtap_rec_init() on the wtap_rec, rather than using its implicit
constructor - there's no guarantee that the initial values of the
structure members, as defined by C (and C++), are what we want.
Use wtap_rec_cleanup() in the destructor; it might do more than the
implied destructor (which does nothing). wtap_rec and Buffer are C
structures, so they don't get C++ constructors and destructors - we have
to use the C ones, which are explicit functions. I think there are
memory leaks that this fixes (packet comments and Buffer for the options
data, leaked when a PacketDialog window is closed).

This reverts commit 9445403f95.
cf_select_packet frees the buffer backing the dissection result
(cf->edt) which results in use-after-frees when callers try to access
the contents. See for example this call trace:
* PacketList::selectionChanged
* cf_select_packet(cap_file_, row)
* frameSelected(row) -> ByteViewTab::selectedFrameChanged
* addTab(source_name, get_data_source_tvb(source))
get_data_source_tvb returns the buffer that backs the dissection and
must remain valid even after dissection has completed. If this is not
done, then a possibly expensive redissection must be done in order to
populate the byte view. The temporary memory savings are not worth it.

Most code that reads from a capture_file already has its own wtap_rec
and Buffer; change the remaining ones to do so as well.

Separate the stuff that any record could have from the stuff that only
particular record types have; put the latter into a union, and put all
that into a wtap_rec structure.
Add some record-type checks as necessary.

We could keep the dialogs with the current content if postponing
proto_free_deregistered_fields() until all dialogs are closed.
This would give a feature where the user is able to compare packets
before and after a reload.
Or we could add functions in PacketDialog to reload the packet details
in all open dialogs. This would give a feature to always have a
updated dialog for all interesting packets.

Move the "find the frame" stuff to openPacketDialog(), and don't even
bother creating a new PacketDialog if we don't find the frame. This
should squelch Coverity CID 1270934, by giving up quickly if fdata is
null.
