include all pkg deps in list of deps returned from update

flatten command to open_port so <17 Erlangs are happy

handle bad package version with error message

Decapitalize short option for 'version' flag

Dep conflict as error

use PRV_ERROR for formattable errors

Also expose it in rebar_api

The option {deps_error_on_conflict, true} will make it so conflicts in
deps being fetched interrupts the operation rather than just display a
warning.

Defaults to `false'.

The deps are sorted and merged, but the merge function merges lists, not
elements. This yields deps that are duplicated and ran for multiple
times.

We first add proper sorts so the keymerge is guaranteed to be fine, and
then do a dedup run to get rid of duplicates if they happen to be.

Fix #267, refactor as/do/namespace interactions

Breaking up initial call to parse from the ones deep inside the provider
parsing to do smarter namespace detection, added 'as' the ability to
look into these also, and cleaned up the code a whole lot that would
depend on implicit assumptions.

A side-effect is that 'do' is now valid for all namespaces, although it
can be overriden.

halt with 0 on successful run

get rid of compile workers

Store base PLT in ~/.cache/rebar3/

set jobs for all compile jobs

merge rebar config opts for parent like done for profiles
