This will reduce the size of crash dumps, especially if
there are large binaries.

Correct several problems parsing sub binaries. A sub binary
would often be replaced with '#CDVNonexistingBinary'.

When parsing a sub binary, we must scan ahead to find the
definition of the refc or heap binary being referenced.

The functions that decode Erlang terms from the crash dump file
take a BinAddrAdj argument to adjust binary addresses in old
crash dumps. To be able to add more decode options in the future,
rename the argument to DecodeOpts and let it be a record.

* siri/cdv/misc-improvements/OTP-14755:
  [cdv] Fix test of size limit reached on crash dump
  [cdv] Display warning if heap is incomplete
  [cdv] Check if dump version is newer than cdv can handle
  [cdv] Add comment about ets tables

If the version of the given crash dump is newer than what
crashdump_viewer is prepared to read, then crashdump_viewer will
display an info dialog and then terminate. This is to allow major
updates of the format of crash dumps.

Commit e1310b8f introduced a bug which caused the observer tool (and
crashdump_viewer) to crash when trying to display an empty binary. The
same change would also cause leading zeros in a binary to disappear in
the preview. The bug is now corrected.

When a literal was used from several processes, the literal would
be dumped in only one of the processes. The other processes
that referenced the literals would have incomplete heap data.

Maps would be dumped as the atom 'undefined', which is
not very informative.
