Reason: Routes, Active Record and the rendering stack should not depend
on the default locale

The inflector was made aware of locales in 7db0b073,
but it defaulted to :en. That should actually be our default
locale instead.

Fixes #10125

This reverts commit c79c6980, reversing
changes made to ba4c2747.

This broke all the tests. See https://travis-ci.org/rails/rails/builds/6061839

This allows you to skip callbacks that are defined by objects, e.g. for
`ActionController`:

    skip_after_filter MySpecialFilter

Previously this didn't work due to a bug in how Rails compared callbacks
in `Callback#matches?`. When a callback is compiled, if it's an object
filter (i.e. not a method, proc, etc.), `Callback` now defines a method on
`@klass` that is derived from the class name rather than `@callback_id`.
So, when `skip_callback` tries to find the appropriate callback to
remove, `Callback` can regenerate the method name for the filter
object and return the correct value for `Callback#matches?`.

Closes #9772.

`TimeWithZone` delegates everything to the wrapped `Time` object
using `method_missing`. The result is that `NoMethodError` error
will be raised in the context of `Time` which leads to a misleading
debug output.

Please see comments on #8156 for some discussion.

Fixed a bug where the inflector would replace camelCase strings and disregarding specified acronyms, fixes #8015

This reverts commit b7d9d6e2.

Per discussion with @jeremy and @rubys on Campfire.

The bug with `ActiveSupport::TimeZone.parse` described in #9678 was
unwittingly fixed in 005d9106 so add some tests to prevent regression.

its payload the same way that ActiveSupport::Notifications does.
Fix spelling in test name.

1. When comparing the directory to delete against the top level
   cache_path, use File.realpath to make sure we aren't comparing two
   unequal strings that point to the same path. This occurs, for
   example, when cache_path has a trailing slash, which it does in the
   default Rails configuration. Since the input to
   delete_empty_directories never has a trailing slash, the comparison
   will never be true and the top level cache directory (and above) may
   be deleted. However…

2. File.delete raises EPERM when trying to delete a directory, so no
   directories have ever been deleted. Changing the code to Dir.delete
   fixes that.

Since all changes from #9347 are related to AS, it seems proper that the
test is placed there as well.

added test for compress options of gzip

update changelog

Modify TimeWithZone#as_json to return 3DP of sub-second accuracy by default, since it's allowed by the spec and is very useful.

this would give us some more clues in case a test silently dies inside Thread

* ASCII_STRING was not an ASCII String
* BYTE_STRING was not an in valid UTF-8 String
* added an assertion for non-UTF-8 String
