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.

catch badarg exception from eunit in `rebar_prv_eunit`

fixes #1469

16.x is not available on chocolatey

Fix printing path with unicode names in prv_update

Allow exclusion of apps in cover

Adds a new option `{cover_excl_apps, Apps}` to exclude apps from coverage
analysis by name.

Add regression test for #1410

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.
