erlc: fixup log message

Using the filename as a prefix is less readable and inconsistent with
the other log messages.

Before:

DEBUG: src/foo.erl depends on...

After:

DEBUG: Dependencies of src/foo.erl ...
erlc: add test suite

Add 'p4' (Perforce) as a dependency type

This calls the 'p4' command-line tool to checkout and sync Perforce
trees. It involves significantly more special code in Rebar than
using 'git p4', but it eliminates the indirection of
Rebar->Git->Python->Perforce
Add partial support for Erlang/OTP 17

Allow rebar to compile applications using Erlang/OTP 17 and older
versions.  This patch only provides partial support since the rebar
tool itself must be compiled using an Erlang/OTP version that is older
than 17.
rebar.app: remove superfluous quoting
Fix 'rebar generate' regression (#253)

If the directory we're about to process contains
reltool.config[.script] and the command to be applied is
'generate', then it's safe to process. We do this to retain the
behavior of specifying {sub_dirs, ["rel"]} and have "rebar generate"
pick up rel/reltool.config[.script]. Without this workaround you'd
have to run "rebar -r generate" (which you don't want to do if you
have deps or other sub_dirs) or "cd rel && rebar generate".
