* siri/cuddle:
  [cdv] Fix test of size limit reached on crash dump, again

* dgud/observer/opt-tv-tab/OTP-14856:
  observer: Fix change accum
  Remove double calls
  observer: Don't crash for late messages
  observer: Optimize tv tab for many tables

This test failed every now and then since the selected max size could
be equal to actual size of the dump - so the dump was not
truncated. This is now corrected.

Make it a virtual table, the only table which was not a virtual table.
Updating 10000 rows with many columns and alternating colors takes too
long time to be a viable solution.

When a process has many links and/or monitors, it could earlier take
very long time to display the process information window. This is now
improved by only showing a few links and monitors, and then an link
named "more..." to expand the rest.

Reading of the "Link list" from a crashdump is also improved.

This bug was introduced by commit 3b964e8dbaa0cd73ca7a983b3ce948e0dbd2c35c

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.

This test failed every now and then since the selected max size could
be greater than the actual size of the dump - so the dump was not
truncated. This is now corrected.
