all: remove deprecated uses of math.rand (#26710)
This PR is a (superior) alternative to https://github.com/ethereum/go-ethereum/pull/26708, it handles deprecation, primarily two specific cases. 

`rand.Seed` is typically used in two ways
- `rand.Seed(time.Now().UnixNano())` -- we seed it, just to be sure to get some random, and not always get the same thing on every run. This is not needed, with global seeding, so those are just removed. 
- `rand.Seed(1)` this is typically done to ensure we have a stable test. If we rely on this, we need to fix up the tests to use a deterministic prng-source. A few occurrences like this has been replaced with a proper custom source. 

`rand.Read` has been replaced by `crypto/rand`.`Read` in this PR.

all: remove database commit callback, rework noderesolver (#26637)
This change ports some changes from the main PBSS PR:

  - get rid of callback function in `trie.Database.Commit` which is not required anymore
  - rework the `nodeResolver` in `trie.Iterator` to make it compatible with multiple state scheme
  - some other shallow changes in tests and typo-fixes

trie: in-place hex prefix, reduce allocs and add rawNode.EncodeRLP

Reintroduce the `[]node` method, add the missing `EncodeRLP` implementation for `rawNode` and calculate the hex prefix in place.

f958d7d482 trie: rework and document key encoding
'encode' and 'decode' are meaningless because the code deals with three
encodings. Document the encodings and give a name to each one.

3f047be5aa all: update license headers to distiguish GPL/LGPL
All code outside of cmd/ is licensed as LGPL. The headers
now reflect this by calling the whole work "the go-ethereum library".
