ethdb/memorydb, trie: reduced allocations (#28473)
* trie: use pooling of iterator states in iterator

The node iterator burns through a lot of memory while iterating a trie, and a lot of
that can be avoided by using a fairly small pool (max 40 items).

name        old time/op    new time/op    delta
Iterator-8    6.22ms ± 3%    5.40ms ± 6%  -13.18%  (p=0.008 n=5+5)

name        old alloc/op   new alloc/op   delta
Iterator-8    2.36MB ± 0%    1.67MB ± 0%  -29.23%  (p=0.008 n=5+5)

name        old allocs/op  new allocs/op  delta
Iterator-8     37.0k ± 0%     29.8k ± 0%     ~     (p=0.079 n=4+5)

* ethdb/memorydb: avoid one copying of key

By making the transformation from []byte to string at an earlier point,
we save an allocation which otherwise happens later on.

name           old time/op    new time/op    delta
BatchAllocs-8     412µs ± 6%     382µs ± 2%   -7.18%  (p=0.016 n=5+4)

name           old alloc/op   new alloc/op   delta

all: update golang/x/ext and fix slice sorting fallout (#27909)
The Go authors updated golang/x/ext to change the function signature of the slices sort method. 
It's an entire shitshow now because x/ext is not tagged, so everyone's codebase just 
picked a new version that some other dep depends on, causing our code to fail building.

This PR updates the dep on our code too and does all the refactorings to follow upstream...

core/state: value diff tracking in StateDB (#27349)
This change makes the StateDB track the state key value diff of a block transition.
We already tracked current account and storage values for the purpose of updating
the state snapshot. With this PR, we now also track the original (pre-transition) values
of accounts and storage slots.

cmd, core/state, eth, tests, trie: improve state reader (#27428)
The state availability is checked during the creation of a state reader.

-    In hash-based database, if the specified root node does not exist on disk disk, then
    the state reader won't be created and an error will be returned.

-    In path-based database, if the specified state layer is not available, then the
    state reader won't be created and an error will be returned.

This change also contains a stricter semantics regarding the `Commit` operation: once it has been performed, the trie is no longer usable, and certain operations will return an error.

all: refactor trie API (#26995)
In this PR, all TryXXX(e.g. TryGet) APIs of trie are renamed to XXX(e.g. Get) with an error returned.

The original XXX(e.g. Get) APIs are renamed to MustXXX(e.g. MustGet) and does not return any error -- they print a log output. A future PR will change the behaviour to panic on errorrs.

core, eth, les, tests, trie: abstract node scheme (#25532)
This PR introduces a node scheme abstraction. The interface is only implemented by `hashScheme` at the moment, but will be extended by `pathScheme` very soon.

Apart from that, a few changes are also included which is worth mentioning:

-  port the changes in the stacktrie, tracking the path prefix of nodes during commit
-  use ethdb.Database for constructing trie.Database. This is not necessary right now, but it is required for path-based used to open reverse diff freezer

core, ethdb, tests, trie: implement NewBatchWithSize API for batcher (#24392)
This PR adds an addtional API called `NewBatchWithSize` for db
batcher. It turns out that leveldb batch memory allocation is
super inefficient. The main reason is the allocation step of
leveldb Batch is too small when the batch size is large. It can
take a few second to build a leveldb batch with 100MB size.

Luckily, leveldb also offers another API called MakeBatch which can
pre-allocate the memory area. So if the approximate size of batch is
known in advance, this API can be used in this case.

It's needed in new state scheme PR which needs to commit a batch of
trie nodes in a single batch. Implement the feature in a seperate PR.

55430b6ea2 trie: implement NodeBlob API for trie iterator
This functionality is needed in new path-based storage scheme, but
can be implemented in a seperate PR though.

When an account is deleted, then all the storage slots should be
nuked out from the disk as well. In hash-based storage scheme they
are still left in the disk but in new scheme, they will be iterated
and marked as deleted.

But why the NodeBlob API is needed in this scenario? Because when
the node is marked deleted, the previous value is also required to
be recorded to construct the reverse diff.

trie: improve the node iterator seek operation (#22470)
This change improves the efficiency of the nodeIterator seek
operation. Previously, seek essentially ran the iterator forward
until it found the matching node. With this change, it skips
over fullnode children and avoids resolving them from the database.

693d9ccbfb trie: more node iterator improvements (#14615)
* ethdb: remove Set

Set deadlocks immediately and isn't part of the Database interface.

* trie: add Err to Iterator

This is useful for testing because the underlying NodeIterator doesn't
need to be kept in a separate variable just to get the error.

* trie: add LeafKey to iterator, panic when not at leaf

LeafKey is useful for callers that can't interpret Path.

* trie: retry failed seek/peek in iterator Next

Instead of failing iteration irrecoverably, make it so Next retries the
pending seek or peek every time.

Smaller changes in this commit make this easier to test:

* The iterator previously returned from Next on encountering a hash
  node. This caused it to visit the same path twice.
* Path returned nibbles with terminator symbol for valueNode attached
  to fullNode, but removed it for valueNode attached to shortNode. Now
  the terminator is always present. This makes Path unique to each node
  and simplifies Leaf.

* trie: add Path to MissingNodeError

The light client trie iterator needs to know the path of the node that's
missing so it can retrieve a proof for it. NodeIterator.Path is not
sufficient because it is updated when the node is resolved and actually
visited by the iterator.

Also remove unused fields. They were added a long time ago before we
knew which fields would be needed for the light client.

4047ccad2f trie: add start key to NodeIterator constructors
The 'step' method is split into two parts, 'peek' and 'push'. peek
returns the next state but doesn't make it current.

The end of iteration was previously tracked by setting 'trie' to nil.
End of iteration is now tracked using the 'iteratorEnd' error, which is
slightly cleaner and requires less code.
