547fa52443net processing: clamp -blockreconstructionextratxn to uint32_t bounds (stickies-v)e451d1e3c6net processing: clamp -maxorphantx to uint32_t bounds (stickies-v)aa89e04e07doc: document PeerManager::Options members (stickies-v) Pull request description: Avoid out-of-bounds user input for `PeerManager::Options` by safely clamping `-maxorphantx` and `-blockreconstructionextratxn`, and avoid platform-specific behaviour by changing `PeerManager::Options::max_extra_txs` from `size_t` to a `uint32_t`. Addresses https://github.com/bitcoin/bitcoin/pull/27499#pullrequestreview-1544114932. Also documents all `PeerManager::Options` members, addressing https://github.com/bitcoin/bitcoin/pull/27499#discussion_r1272302469.
