Add rebar3.crashdump to gitignore template

Fix regex match for ignored file

add `get-deps` provider

The regex mistakenly matched too many files (any character followed by
an underscore) rather than only files starting in '._'

This properly escapes the expressions to work in all cases.

Update THANKS

Select git clone command by git version

The option --single-branch was introduced in git version 1.7.10 and
thus rebar3 cannot fetch git dependencies on systems where earlier
git versions are install.

This commit will select other git clone commands if an earlier git
version is detected. If the git version cannot be determined rebar3
falls back on the previous behavior and uses --single-branch.

a no-op provider that depends on lock that is slightly more discoverable and user friendly

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.

Replace unprocessed ~n linebreaks

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
