56a461f727 wallet: fix buffer over-read in SQLite file magic check (Sebastian Falbesoner)
Pull request description:
Looking at our new SQLite database code, I noticed that there is a potential problem in the method `IsSQLiteFile()`: If there is no terminating zero within the first 16 bytes of the file, the `magic` buffer would be over-read in the `std::string` constructor for `magic_str`. Fixed by using the "from buffer" variant of the string ctor (that also takes a size) rather than the "from c-string" variant (see http://www.cplusplus.com/reference/string/string/string/).
The behaviour can be reproduced by the following steps:
* Creating a file of at least 512 bytes in size (to pass the minimum size check) that doesn't contain zero bytes in the magic area, e.g. simply:
`$ python3 -c "print('A'*512)" > /tmp/corrupt_wallet`
* Showing content and size of the `magic_str` string in case the magic check fails
* Create a simple unit test that simply calls `IsSQLiteFile` with the corrupt wallet file
* Run the unit test and see the random gibberish output of `magic_str` after 16 `A`s :-)
Or, TLDR variant, just get the branch https://github.com/theStack/bitcoin/tree/reproduce_sqlite_magic_overread, compile unit Tests and run the script `./reproduce_sqlite_magic_overread.sh`.
Note that this is the minimal diff, probably it would be better to avoid `std::string` at all in this case and just use `memcmp`, strings that include null bytes are pretty confusing.

be386840d4 test: Replace use of (dis)?connect_nodes globals (Elliott Jin)
Pull request description:
`util.py` defines global helper functions `connect_nodes` and `disconnect_nodes`; however, these functions are confusing because they take a node and an index (instead of two indexes).
The `TestFramework` object has enough context to convert from `i` to `self.nodes[i]`, so we can replace all instances of `connect_nodes(self.nodes[a], b)` with `self.connect_nodes(a, b)`. Similarly, we can replace instances of `disconnect_nodes`.
The approach taken in this PR builds on #19945 but uses a scripted-diff for the majority of the changes.

c8abbc9d1f p2p: declare Announcement::m_state as uint8_t, add getter/setter (Jon Atack)
Pull request description:
Change `Announcement::m_state` in `tx_request.cpp` from type `State` to `uint8_t` and add a getter and setter for the conversion to/from `State`. This should silence these travis ci gcc compiler warnings:

too small to hold all values of ‘enum class {anonymous}::State’

The gcc warnings are based on the maximum value held by the underlying uint8_t enumerator type, even though the intention of the bitfield declaration is the maximum declared enumerator value. They have apparently been silenced in gcc 8.4+ and 9.3+ according to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61414.

bd5215103e random: fixes read buffer resizing in RandAddSeedPerfmon (Ethan Heilman)
Pull request description:
As shown below when resizing the read buffer `vData` `std::max((vData.size() * 3) / 2, nMaxSize)` is used. This means that the buffer size immediately jumps to `nMaxSize`. I believe the intend of this code is to grow the buffer size through several steps rather than immediately resize it to the max size.
```cpp
std::vector<unsigned char> vData(250000, 0);
long ret = 0;
unsigned long nSize = 0;
const size_t nMaxSize = 10000000; // Bail out at more than 10MB of performance data
while (true) {
nSize = vData.size();
ret = RegQueryValueExA(HKEY_PERFORMANCE_DATA, "Global", nullptr, nullptr, vData.data(), &nSize);
if (ret != ERROR_MORE_DATA || vData.size() >= nMaxSize)
break;
vData.resize(std::max((vData.size() * 3) / 2, nMaxSize)); // Grow size of buffer exponentially
}
```
vData always starts at size 250,000 and nMaxSize is always 10,000,000 so the first time this line is reached:
```cpp
vData.resize(std::max((vData.size() * 3) / 2, nMaxSize));
```
the effect will always be to resize vData to nMaxSize. Then because the loop terminates when vData.size >= 10,000,000 only one resize operation will take place.
To fix this issue we replace `std::min` with `std::max`
This PR also adds a comment clarifying the behavior of this function the first time it is called.

Pull request description:

3333077823 rpc: Adjust witness-tx deserialize error message (MarcoFalke)
cccc752569 rpc: Properly deserialize txs with witness before signing (MarcoFalke)
Pull request description:
