Also small output fix in rebar3 shell

Fix override_deps test from suite rebar_compile_SUITE

Auto-boot main app in OTP app project templates

Use maps for child spec example

People are starting to expect these niceties! It's also easier to drop
the config when you know it's there than add it when you don't know it
exists.

Restore default templates in bootstrapped rebar3

When allowing Dialyzer to work internally, we moved a bunch of
config (such as no_debug_info) to the prod profile, but the escript
included files remained locked onto the default profile.

Because the bootstrapping phase now happened in a prod run, the priv/
dirs were never created for the default profile unless a prior run
existed, which hid the bug from us.

This patch overrides the path on the prod profile so that we don't rely
on accidental leftovers for things to work on a bootstrap phase as a
dev.

Officially drop Erlang R16B support—Logger support in cth_readable, and compact CT output

Required for the Logger interface to be supported since it relies on
maps

cth_readable 1.4.0 supports the new logger interface from OTP-21, which
likely breaks compatibility with R16 builds.

It also includes a new compact interface, displaying output such as:

    ===> Running Common Test suites...
    %%% rebar_alias_SUITE: ......
    %%% rebar_as_SUITE: ...........
    %%% rebar_compile_SUITE:................................
    ............................
    %%% rebar_compile_SUITE ==> test_name: SKIPPED
    %%% rebar_compile_SUITE ==>
    {tc_user_skip,"compile:env_compiler_options/0 available"}
    ..
    %%% rebar_cover_SUITE: .............
    %%% rebar_ct_SUITE: ....................................

Allowing to display more tests within less screen space.
This mode has been added to the ct_readable option under the name
'compact' (now supporting true | false | compact), and has been made
default for rebar3.

Re-disable debug_info on prod profile

Had mistakenly only disabled it for deps.

Work around OTP-21 deprecation of get_stacktrace() and other incompatible changes
