UniquenessValidator exclude itself when PK changed

When changing the PK for a record which has a uniqueness validation on
some other attribute, Active Record should exclude itself from the
validation based on the PK value stored on the DB (id_was) instead of
its new value (id).

In Rails 5, we're much more restrictive about when we do or don't cache
a prepared statement. In particular, we never cache when we are sending
an IN statement or a SQL string literal
However, in the case of Adequate Record, we are *always* sending a raw
SQL string, and we *always* want to cache the result.
Fixes #23507

This commit walks the reflection tree and builds the scope chain
functionally. It also removes the chain cache since the cache doesn't
seem to have any impact on performance (I'd prefer to only cache at
proven bottlenecks)

`schema_type` returns symbol rather than string

| | | | | | | | | |
| | | | | | | | | |
| | | | | | | | | | |
A return value of `schema_type` is used by:
1. primary key type: using as `symbol.inspect`
2. normal column type: using as `symbol.to_s`
It is better to return symbol.

With this addition, you can add a column into the table like:
```
create_table(:numeric_types) do |t|
t.numeric :foo, precision: 10, scale: 2, default: 2.0
end
```
The result of the migration above is same with:
```
create_table(:numeric_types) do |t|
t.decimal :foo, precision: 10, scale: 2, default: 2.0
end

This reverts commit 99801c6a7b69eb4b006a55de17ada78f3a0fa4c1.
Ultimately it doesn't matter whether `add_index` or `t.index` are used
in the schema dumper in any meaningful way. There are gems out there
which hook into the old behavior for things like indexing materialized
views. Since the reverted commit doesn't seem to add much benefit,
there's no reason for us to break these gems.

If you set the DATABASE_URL environment variable to `mydatabase` by accident, you end up getting a series of errors that are hard to trace. For example:
```
warning: already initialized constant ActiveRecord::Base::OrmAdapter
```
Turns out the cascade of errors is due to the error raised by `.tr` being called on `nil`.
This commit makes sure that `scheme` is set before calling `.tr` on it. My previous iteration used `@uri.scheme.try(:tr, '-', '_')` but using the `&&` logical operator is a fair bit faster: http://stackoverflow.com/questions/26655032/try-vs-performance
With this change, the error message becomes much more understandable:
```
FATAL: database "mydatabase" does not exist (ActiveRecord::NoDatabaseError)
```

We had previously updated this to attempt to map over whatever was
passed in, so that additional types like range and array could benefit
from this behavior without the time zone converter having to deal with
every known type.
However, the default behavior of a type is to just yield the given value
to `map`, which means that if we don't actually know how to handle a
value, we'll just recurse infinitely. Since both uses of `map` in this
case occur in cases where we know receiving the same object will
recurse, we can just break on reference equality.
Fixes #23241.

This reverts commit f6db31ec16e42ee7713029f7120f0b011d1ddc6c.
Reason:
Scope names can very easily conflict, particularly when sharing Concerns
within the team, or using multiple gems that extend AR models.
It is true that Ruby has the ability to detect this with the -w option, but the
reality is that we are depending on too many gems that do not care about Ruby
warnings, therefore it might not be a realistic solution to turn this switch on
in our real-world apps.

Fix corrupt transaction state caused by `before_commit` exceptions

| | | | | | | | | |
When a `before_commit` callback raises, the database is rolled back but
AR's record of the current transaction is not, leaving the connection in
a perpetually broken state that affects all future users of the
connection: subsequent requests, jobs, etc. They'll think a transaction
is active when none is, so they won't BEGIN on their own. This manifests
as missing `after_commit` callbacks and broken ROLLBACKs.
This happens because `before_commit` callbacks fire before the current
transaction is popped from the stack, but the exception-handling path
they hit assumes that the current transaction was already popped. So the
database ROLLBACK is issued, but the transaction stack is left intact.
Common cause: deadlocked `#touch`, which is now implemented with
`before_commit` callbacks.
What's next:
* We shouldn't allow active transaction state when checking in or out
from the connection pool. Verify that conns are clean.
* Closer review of txn manager sad paths. Are we missing other spots
where we'd end up with incorrect txn state? What's the worst that can
happen if txn state drifts? How can we guarantee it doesn't and
contain the fallout if it does?
Thanks for @tomafro for expert diagnosis!
