Make ssh_cli.erl handle <CTRL>+C

Dear all,

I've found that ssh_cli.erl does not scan the input received from the
remote for occurrences of <CTRL>+C to signal the user's interrupt
requests to the group_leader of the CLI session. The patch attached to
this e-mail fixes the issue.

Kind regards,

Subject: [PATCH] [SSH-CLI] properly handle <CTRL>+C as shell interrupt

In ssh_cli.erl, check for the presence of <CTRL>+C in data received from
the remote. If detected, use the established mechanism (send an
'interrupt' exit signal to the group_leader) to signal an interrupt to
the shell.
handle_info Info type possible typo

Should it be 'timeout' instead of timeout(), as in doc: http://www.erlang.org/doc/man/gen_server.html#Module:handle_info-2?
ssh: Not run chmod every lookup
[sasl] Remove directory with unicode characters after successful test

This is to avoid lingering files after test runs on windows, since the
cleanup script often does not succeed in removing files with unicode
characters.
[common_test] Add documentation for ct_netconfc:send and send_rpc
[ct_netconfc] Allow multiple elements inside filter in create_subscription

ct_netconfc:create_subscription only allows one XML element inside the
'filter' element. According to RFC5277 it should be allowed to add any
number of elements inside the filter, so this is now corrected.
