Pull request description:
This PR enables validation dry-runs of packages through the `testmempoolaccept` RPC. The expectation is that the results returned from `testmempoolaccept` are what you'd get from test-then-submitting each transaction individually, in that order (this means the package is expected to be sorted in topological order, for now at least). The validation is also atomic: in the case of failure, it immediately halts and may return "unfinished" `MempoolAcceptResult`s for transactions that weren't fully validated. The API for 1 transaction stays the same.
**Motivation:**
- This allows you to test validity for transaction chains (e.g. with multiple spending paths and where you don't want to broadcast yet); closes#18480.
- It's also a first step towards package validation in a minimally invasive way.
- The RPC commit happens to close#21074 by clarifying the "allowed" key.
There are a few added restrictions on the packages, mostly to simplify the logic for areas that aren't critical to main package use cases:
- No package can have conflicts, i.e. none of them can spend the same inputs, even if it would be a valid BIP125 replacement.
- The package cannot conflict with the mempool, i.e. RBF is disabled.
- The total count of the package cannot exceed 25 (the default descendant count limit), and total size cannot exceed 101KvB (the default descendant size limit).

e40224d0c7 Remove unused float serialization (MarcoFalke)
Pull request description:
Based on #21981.
This adds a software-based platform-independent float/double encoder/decoder (platform independent in the sense that it only uses arithmetic and library calls, but never inspects the binary representation). This should strengthen our guarantee that encoded float/double values are portable across platforms. It then removes the functionality to serialize doubles from serialize.h, and replaces its only (non-test) use for fee estimation data serialization with the software encoder.
At least on x86/ARM, the only difference should be how certain NaN values are encoded/decoded (but not *whether* they are NaN or not).
It comes with tests that verify on is_iec559 platforms (which are the only ones we support, at least for now) that the serialized bytes exactly match the binary representation of floats in memory (for non-NaN).

When building for Android, _GNU_SOURCE will be defined, but it doesn't
actually have the fopencookie() function, or define the
cookie_io_functions_t type.
For now just skip trying to use it if we are building for Android.
Should fix#22062.
Maximum number of transactions allowed in a package is 25, equal to the
default mempool descendant limit: if a package has more transactions
than this, either it would fail default mempool descendant limit or the
transactions don't all have a dependency relationship (but then they
shouldn't be in a package together). Same rationale for 101KvB virtual
size package limit.
Note that these policies are only used in test accepts so far.
This allows us to easily create transaction chains for package
validation. We don't test_accept if submit=false because we want to be
able to make transactions that wouldn't pass ATMP (i.e. a child
transaction in a package would fail due to missing inputs).

fafd121026 refactor: Make CFeeRate constructor architecture-independent (MarcoFalke)
Pull request description:
Currently the constructor is architecture dependent. This is confusing for several reasons:
* It is impossible to create a transaction larger than the max value of `uint32_t`, so a 64-bit `size_t` is not needed
* Policy (and consensus) code should be arch-independent
* The current code will print spurious compile errors when compiled on 32-bit systems:
```
policy/feerate.cpp:23:22: warning: result of comparison of constant 9223372036854775807 with expression of type 'size_t' (aka 'unsigned int') is always true [-Wtautological-constant-out-of-range-compare]
assert(nBytes_ <= uint64_t(std::numeric_limits<int64_t>::max()));
```
Fix all issues by making it arch-independent. Also, fix `{}` style according to dev notes.

Allow CheckSequenceLocks to use heights and coins from any CoinsView and
CBlockIndex provided. This means that CheckSequenceLocks() doesn't need
to hold the mempool lock or cs_main. The caller is responsible for
ensuring the CoinsView and CBlockIndex are consistent before passing
them in. The typical usage is still to create a CCoinsViewMemPool from
the mempool and grab the CBlockIndex from the chainstate tip.

Pull request description:
While reviewing #20196, I noticed the `NetPermissionFlags` enums are frequently called as if they were scoped, yet are still global. This patch upgrades `NetPermissionFlags` to a scoped class enum and updates the enumerator naming, similarly to #19771. See https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#enum-enumerations for more info.
This change would eliminate the class of bugs like https://github.com/bitcoin/bitcoin/pull/20196#discussion_r610770148 and #21644, as only defined operations on the flags would compile.
