erts: Fix cache alignment for ETS write_concurrency locks

Effects if sizeof(erts_smp_rwmtx_t) > 64:
+ Better performance due to less false sharing
- Increased memory footprint per table

  erts: Fix cache alignment for ETS write_concurrency locks
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.
