... before calling erlang:function_exported(ct_testspec,get_tests,1).

Parse given test specs and add all spec- and suite directories as
extra_src_dirs in order to ensure that all these directories are
copied to the _build area and the suites are compiled.

Specs located in the project- or app root are explicitly copied to the
_build area in order to avoid recursive copying of the complete
directory tree.

This is a bugfix. It makes sure that the given path to a testspec is
translated so common_test will pick the spec from the _build
directory, and not from the source tree.

This is necessary in order to automatically get the testspec included
as an artifact (i.e. copied to the _build dir) in the case when it is
stored in another directory than 'test'.

Bug: option 'spec' is not specifically handled when merging options
from the command line with options from rebar.config. Due to this, if
the config specifies a 'spec', then this will take precedence over any
'dir' and/or 'suite' on the command line.

This commit takes special care of all options that can be used to
select tests - meaning that if any of the options 'spec', 'dir',
'suite', 'group' or 'case' are specified on the command line, then all
'spec', 'dir', 'suite', 'group' and 'case' options in rebar.config
will be ignored.

Restrict regexp to match on files starting with '._'

Correct precedence of compile options merged from profiles.

Ensures merged compiler options end up in the correct order to maintain profile precedence.

Moves the merge functionality from rebar_opts:merge_opts/2 to a standalone function to ease extension and debugging.

Fixes #1392

Upgrade relx, erlware_commons and cf

relx ~> 3.22.0
erlware_commons ~> 0.22.0
cf ~> 0.2.2

Add 'recursive' option

Unify different styles of missing_package error

use default region for s3 deployment

Always read REBAR_CONFIG env var when loading config

upload rebar3 escript for every merge to master to rebar3-nightly

The option {recursive,boolean()} can now be set pr directory in
'src_dirs' and 'extra_src_dirs', and on top level in the new
'erlc_compiler' option. Example config:

{erlc_compiler,[{recursive,false}]}.
{src_dirs,[{"src",[{recursive,true}]}]}.

This will cause recursive compilation within the "src" directory, but
not in any other directoires.

Allow rebar3 to edoc itself

Fix rebar3 dialyzer warnings

Some tricky changes in there but should be okay

Add exclude_apps/mods, plt_extra_mods, base_plt_mods config

Fix usage decription of 'rebar3'

* exclude_apps - never use applications for PLT/analysis
* base_plt_mods - add modules to base PLT (overrules exclude_apps)
* plt_extra_mods - add modules to PLT (overrules exclude_apps)
* exclude_mods - never use modules for PLT/analysis (overrules all)

experimental: allow test specifications to be passed via the command line

`rebar3 ct --spec foo.spec,bar.spec,baz.spec` now works

also added support for the `join_specs` flag on the command line
