Unwrap Constraints objects. I don't actually think it's possible
to pass a Constraints object to this constructor, but there were
multiple places that kept testing children of this object. I
*think* they were just being defensive, but I have no idea.

this also changes the constructor. We don't need to pass more options
than "defaults" (whatever defaults are, ugh. probably another hash of
stupid stuff).

this decouples our code from the env hash a bit.

The optimized and non-optimized path share more code now without
significant performance degretation

Example:
x = [1,2,3,4]
y = [3,2,1]
def test x, y
hash = {}
x.zip(y) { |k,v| hash[k] = v }
hash
end
def test2 x, y
Hash[x.zip(y)]
end
def test3 x, y
x.zip(y).each_with_object({}) { |(k,v),hash| hash[k] = v }
end
def stat num
start = GC.stat(:total_allocated_object)
num.times { yield }
total_obj_count = GC.stat(:total_allocated_object) - start
puts "#{total_obj_count / num} allocations per call"
end
stat(100) { test(x,y) }
stat(100) { test2(x,y) }
stat(100) { test3(x,y) }
__END__
2 allocations per call
7 allocations per call
8 allocations per call

The bit of URL generation that is optimized is the generation of
the path so things like :host, :port, etc. are irrelevant.

Then we can avoid nil checks

this way we can stop checking respond_to on every call.

1. Escape '%' characters in URLs - only unescaped data
should be passed to URL helpers
2. Add an `escape_segment` helper to `Router::Utils`
that escapes '/' characters
3. Use `escape_segment` rather than `escape_fragment`
in optimized URL generation
4. Use `escape_segment` rather than `escape_path`
in URL generation
For point 4 there are two exceptions. Firstly, when a route uses wildcard
segments (e.g. *foo) then we use `escape_path` as the value may contain '/'
characters. This means that wildcard routes can't be optimized. Secondly,
if a `:controller` segment is used in the path then this uses `escape_path`
as the controller may be namespaced.
Fixes #14629, #14636 and #14070.

In Rails 3.2 you only needed pass an argument for dynamic segment once so
unique the segment keys array to match the number of args. Since the number
of args is less than required parts the non-optimized code path is selected.
This means to benefit from optimized url generation the arg needs to be
specified as many times as it appears in the path.
Fixes #12808

When an optimized helper fails to generate, show the full route constraints
in the error message. Previously it would only show the contraints that were
required as part of the path.

Using a Regexp to replace dynamic segments in a path string is fraught
with difficulty and can lead to odd edge cases like #13349. Since we
already have a parsed representation of the path it makes sense to use
that to generate an array of segments that can be used to build an
optimized route's path quickly.
Tests on a simple route (e.g. /posts/:id) show a speedup of 35%:

Current Helper: 5274 i/100ms
New Helper: 8050 i/100ms

Current Helper: 79263.6 (±3.7%) i/s - 395550 in 4.997252s
New Helper: 153464.5 (±4.9%) i/s - 772800 in 5.047834s
Tests on a more complex route show even an greater performance boost:

New Helper: 78815.5 (±4.1%) i/s - 398268 in 5.062161s
It also has the added benefit of fixing the edge cases described above.
Fixes #13349

This reverts commit 70d6e16fbad75b89dd1798ed697e7732b8606fa3, reversing
changes made to ea4db3bc078fb3093ecdddffdf4f2f4ff3e1e8f9.
Seems to be a code merge done by mistake.
