Fix typo in common_test documentation for the -join_specs flag
Report wall clock time instead of runtime when crashing

On SMPs, the time reports that Dialyzer produced when crashing were
inaccurate. Fix this by using wall_clock rather than runtime.
Remove release note unrelated to functionality
Fix doc typo: required -> requires
Remove case expecting a pre-R16B return value from os:type/1

The documented return value changed in commit c37a9761.
Remove unused diameter_dbg:log/4

It was intended to replace diameter_lib:log/4 at some point but that was
a bad idea since diameter_dbg isn't included in the app file.
Include compiler and info modules in app file

Albeit as comments. This is just to make it more obvious that these
aren't include in the modules list, since they typically aren't
needed/wanted on a target system. Also add comments for the
corresponding dependencies on syntax_tools and runtime_tools, as well as
the optional runtime dependency on ssl.
Move info modules into own subdirectory

Possibly overkill for two modules but it mirrors their different
treatment by the makefile.
Export type application:start_type()

Also use this type in the start/2 callback spec.
Fix reference to start_type() i application(3)
