List 'lock' command in man page

Allow single test spec in ct_opts

The option {spec,Specs} is allowed in ct_opts, but
rebar_prv_common_test:test_dirs did not take into account that Specs
could also be a string only, i.e. not a list of strings.

Properly warn on missing rebar3 deps: add inets

rebar_utils:escape_chars handles quotes

rebar_file_utils:cp_r uses rebar_utils:escape_chars to ensure that the file names are safe to use, but it doesn't escape double and single quotes. If the file name includes those characters, they disappear when the shell processes them and we get "file not found" errors.

The main culprit here is eunit, that creates reports whose names are `TEST-file_"myfile.app".xml`, and I wish it didn't but I think escape_chars should still do its job all the way.

Fix wildcard usage in rebar3 clean

Bump cth_readable to 1.2.4

Fixes an issue where some skipped test suites could end up misreported
as the previous suite. See

Add respect for src_dirs option in app_discover and app_info

This also patches up a problem for hooks when dealing with directories
with spaces in them, and reduces complexity of bootstrap file.

The finding of the file was done based on an assumed 'src' path which
may not be correct. This patch instead replaces the value with a lookup
in configured paths and returns the first that matches to an existing
file.

First find the rebar.config file, and if any data is found, check for
src_dirs config. If nothing is there or no app is found, default to src/

This makes rebar_prv_install_deps able to support more src_dir configs

This lets people who use custom directories layout without leaving the
.app.src in src/ to still see their app build.

use proper skips in compiler tests that use unavailable functions

Add support for global plugin-defined templates

Did not really know how to automate the testing for this, did it by
hand.
