consider `ERL_COMPILER_OPTIONS` when recompiling

on 19.x forward the compiler should now take into consideration the value
of the environment variable `ERL_COMPILER_OPTIONS` when deciding whether
or not to recompile a module

The stable URL is for stable releases since 3.0.0

Addresses issue #1330

Survive EDoc crashes

Instead of a hard crash, display an error message indicating which app
failed.

We can't report the exact failure; only EDoc does it to stdout itself
and we can't capture it.

Pre/Post hooks are run properly despite the failure, as per escript and
compile providers.

Add manpage for rebar3

See template local install same builtin as escript

Fix `mv` on windows

and clean up a bit

to be roundtripped again to windows.

Requires changing a bunch of arguments for xerocopy since it
does not allow to rename while copying.

Lots of tests added

Fixed typos and grammar errors for CONTRIBUTING.md.

With peer script to help autogenerate commands from providers

Relative dialyzer paths

Fixes issue #880

May break backwards compat with projects that manually called the
dialyzer formatter, but we never documented or expected this to be
exposed.

This allows to reuse the code for any provider that formats source files
out to the user.

The option to configure it does remain compiler-centric for backwards
compatibility

When the `new` command is run from a locally installed rebar3 (`rebar3
local install`), the builtin templates would be labelled as custom
because of directories.

This patch fixes it by splitting off the rebar3 priv dir from the user's
configured plugin path for custom ones, and introducing a new internal
label for builtins (since handling must remain different from escripts)

This fixes issue #819

Fixed missing hypens, and improper wording in README.md

[FEATURE] Add .editorconfig Settings.

https://github.com/erlang/rebar3/issues/1443

upgrade erlware_commons to 1.0.0 for OTP20 support

upgrade relx to fixed hex package 3.22.2

add option to pass args to user_drv for custom shells

Bump relx to 3.22.1

Type specifications and edocs improvements

Improve merge of command line options and config options in CT

refine eunit test detection

application modules will be added to the eunit test set automatically, no
need to consider them for inclusion in the test set separately

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

stops the eunit provider from filtering out test modules based on the
file extension. previously, it was hardcoded to expect all test files
ended in `.erl`. this change allows for endings like `.lfe` and `.beam`

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.

shell: don't crash apps that use release version operators

the releases website has changed

Like for instance: {app, "0.1.0", '='}
