Properly handle fields too short in io_lib_format

Values for which the precision or field width were too small in io_lib_format
could trigger an infinite loop or crash in term/5.

ssl: parse SNI in received client hello records
jinterface: OtpInputStream exceptions show useless value

Arrays have no meaningful toString method, but one must use
Arrays.toString instead. The meaningless value would look for example
like "[C@16f0472", instead of "[2,4]".

Fix typo in Advanced chapter
inets: Add reload tests
inets: Create seperate timeout for TLS/SSL handshake

We do not want this timeout to be mixed up with the keep alive timeout.
We will probably want to make it configurable later.

edoc, syntax_tools: Don't fail on invalid UTF-8

As a temporary measure to ease the transition to default UTF-8
encoding, automatically fall back to the Latin-1 encoding (without any
warnings; the Erlang Compiler will emit a proper warning).

The intention is to remove this workaround in OTP 18 or 19.

Add 'disksup_posix_only' parameter to disksup

On embedded (Linux) systems the "df" program is very often provided by
the Busybox (or Toolbox) project. This version does not provide the "-l"
option (for displaying only local filesystems) used in disksup.erl.

To make disksup work on these embedded platforms, this patch adds a new
application parameter 'disksup_posix_only', to make diskup use only
options defined in the POSIX standard:
