Do not gsub non ASCII characters in header anchor.
Use `break` instead of `next` in AD::Journey::Formatter#match_route

The array is sorted in descending order, so there is no point in
iterating further if we met a negative item - all the rest will be
negative too.
Fix the hash key being delete from env

It was changed by mistake at c5d64b2b86aa42f57881091491ee289b3c489c7e.

[Guides] Do not gsub non ASCII characters in header anchor.
Allow additional arguments to be used during type map lookups

Determining things like precision and scale in postgresql will require
the given blocks to take additional arguments besides the OID.

- Adds the ability to handle additional arguments to `TypeMap`
- Passes the column type to blocks when looking up PG types
Use the generic type map for all PG type registrations

We're going to want all of the benefits of the type map object for
registrations, including block registration and real aliasing. Moves
type name registrations to the adapter, and aliases the OIDs to the
named types

Remove unnecessary `Hash#to_a` call

Inspired by https://github.com/rails/rails/commit/931ee4186b877856b212b0085cd7bd7f6a4aea67

```ruby

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

h = { 'x' => 'y' }

stat(100) { h.     each { |pair| pair } }
stat(100) { h.to_a.each { |pair| pair } }

__END__
1 allocations per call
2 allocations per call
```

Move `extract_precision` onto type objects
Push scale to type objects

Ideally types will be usable without having to specify a sql type
string, so we should keep the information related to parsing them on the
adapter or another object.

Columns and injected types no longer have any conditionals based on the
format of SQL type strings! Hooray!
