core/txpool: implement additional DoS defenses (#26648)
This adds two new rules to the transaction pool:

- A future transaction can not evict a pending transaction.
- A transaction can not overspend available funds of a sender.

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`rand.Read` has been replaced by `crypto/rand`.`Read` in this PR.

common/prque: generic priority queue (#26290)
* common, core, eth, les, trie: make prque generic

* les/vflux/server: fixed issues in priorityPool

* common, core, eth, les, trie: make priority also generic in prque

* les/flowcontrol: add test case for priority accumulator overflow

* les/flowcontrol: avoid priority value overflow

* common/prque: use int priority in some tests

No need to convert to int64 when we can just change the type used by the
queue.

* common/prque: remove comment about int64 range

all: make timestamp-based fork checks based on uint64 (#26474)
This PR changes the API so that uint64 is used for fork timestamps.
It's a good choice because types.Header also uses uint64 for time.

all: assign zero after resize in implementations of heap.Interface (#26296)
This changes the Pop method to assign the zero value before
reducing slice size. Doing so ensures the backing array does not
reference removed item values.
