If escaping :, then links of type "file:///c:/ldisk..." will not work.

Escaping @ does not create any problems, but the link becomes harder
to read and most modern browsers can handle this.

Skipping test_server_latin1_***_SUITE if filename:native_name_encoding
is utf8.

* siri/cross-cover/OTP-9870:
  [test_server] Don't use print/3 in cross_cover_analyse
  [common_test] Add documentation for cross cover analysis
  [common_test] Add test case for cross cover mechanism
  [test_server] Update documentation about cross cover
  [test_server] Add test of code cover mechanism
  [test_server,common_test] Fix cross cover mechansim

Before terminating slave nodes, test_server calls cover:flush/1 to
fetch data from the node without actually stopping cover on this
node. If cover is not stopped for the node and a new node with the
same name is started, then cover will be started on the new node. To
avoid this test_server now calls cover:stop/1 after the slave node is
terminated.

* siri/test_server/erl2html-indent-problem/OTP-9710:
  [test_server] Minimize memory usage in erl2html2:convert/[2,3]
  [test_server] Fix erl2html2.erl to handle badly indented files

Reading form by form and line by line, instead of reading the complete
file in one go.

Line numbering of erlang files that were not correctly indented could
be wrong after coverting to html with erl2html2:convert/[2,3]. This has
been corrected.

This commit also fixes the following:

* There are now link targets for each line and not only for each 10th
  line - meaning that links from test logs are now to the exact line,
  and not to the last number for which N rem 10 == 0.
* there will only be one link target per function, i.e. the faulty
  link targets for function clauses are removed.
* link targets for function now includes the arity (e.g. func/1 has a
  link target "func-1")

And some tests are added.
