note: print() statements and stderr logging don't have a consistent printing order.
Either can buffer log lines and flush them later, and the buffers are independent.
Just prior to this commit, test_fork_conflict and test_fork_noconflict were essentially identical copies.
The only diff was that test_fork_conflict set the global blockchain.blockchains,
but this was not even affecting its behaviour anymore.
Originally when this test was added, we had the concept of chain fork conflicting with each other:
we could not handle three-way chain-splits. As in, there could only be a single fork forking away
from the main chain at any given height.
see 7221fb3231
However, this restriction was removed and generalised later:

After which the "test_fork_conflict" test did not make sense anymore.
We try to predict the next headers the interface will ask for,
and request them ahead of time, to be kept in the headers_cache.
This saves network latency/round-trips, for a bit more memory usage
and in some cases for more bandwidth.
Note that due to PaddedRSTransport.WAIT_FOR_BUFFER_GROWTH_SECONDS,
latency saved here can be longer than "real" network latency.
This speeds up
- binary search greatly,
- backwards search to a small degree
(although not that much as its algorithm should be changed a bit to make it cache-friendly)
- catch-up greatly, if it's <10 blocks behind
What remains is to speed up catch-up in case we are behind by many thousands of block.
That behaviour is left unchanged here. The issue there is that we request chunks sequentially.
So e.g. 1 chunk (2016 blocks) per 1 second.
changes qeswaphelper to shate a single, long lived transport instance
instead of opening new transports to do swaps and fetch offers.
This allows to continuosly fetch offers, so events which get returned
later by slow relays don't get missed and the fee values stay updated.
Also fixes a race causing the list to miss some swapservers, as the
current implementation fetches only until
`swap_manager.is_initialized()` is set, which will get set as soon as an
event of the configured swapserver is received. So if the event of the
configured swapserver is received as first, all server events coming in
after it would get ignored.

note: 3.12 just transitioned to security-only status,
so can't bump win/mac binaries without switching to 3.13
(as we don't compile our own cpython for those)
note: some files have two versions in them, e.g.:
```
assert CffiRecipe._version == "1.15.1"
class CffiRecipePinned(util.InheritedRecipeMixin, CffiRecipe):
version = "1.17.1"
```
The assert is left there as I think it might be useful to get a failure if we rebase p4a
and the upstream recipe version changes. There might be substantial changes in the upstream
recipe that we need to adapt to. In the happy case, if we rebase p4a, we just have to manually
update these asserts to the new versions at that time.
