If JavaScript runtime is not installed, execjs fails with error quietly,
while tests continue to run. This should not happen since it causes tests
to fail for unknown reason (#6621).

This commit assures that if JavaScript runtime is not installed, an assertion
is raised.

In the current router DSL, using the +match+ DSL
method will match all verbs for the path to the
specified endpoint.

In the vast majority of cases, people are
currently using +match+ when they actually mean
+get+. This introduces security implications.

This commit disallows calling +match+ without
an HTTP verb constraint by default. To explicitly
match all verbs, this commit also adds a
:via => :all option to +match+.

Closes #5964

This case was not tested and documentation was a bit confusing
on that topic, so it was not obvious if current code
works properly or not.

When default_asset_host_protocol is left as nil, it will use absolute protocols when a request is present, and relative protocols otherwise (eg in asset generation)

Skip broken asset precompilation test on Macs. Issues with NFD vs NFC normalization on the asset filename. Major red flag with asset lookups!

Provide initialize_on_precompile which, when set to false, does not initialize the app for precompilation. Defaults to true.

Avoid use of existing precompiled assets during rake assets:precompile run

To the app developer, this means configuration add in
config/initializers/* will not be executed.

Plugins developers need to special case their initializers that are
meant to be run in the assets group by adding :group => :assets.
