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.

  ssl/ssh: Remove/ignore unused XML_FILES doc files
  Refactor xmllint check and make it fail on failure
  Add toplevel xmllint make target

* 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

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.

This commit also adds a check to see that all files that
are part of an xi:include also have part of XML_FILES
and vice versa. It also fixes any applications where this
was not true.
