These tests never run as the build tag excluded them from the CI
execution. As a results the (dead) code got out of sync with other
parts of Swarm and now they would not even compile. => Removed.

* p2p/discover: remove unused function
* p2p/enode: use localItemKey for local sequence number
I added localItemKey for this purpose in #18963, but then
forgot to actually use it. This changes the database layout
yet again and requires bumping the version number.
* node: require LocalAppData variable
This avoids path inconsistencies on Windows XP.
Hat tip to @MicahZoltu for catching this so quickly.
* node: fix typo
* travis, build: switch to NDK 19b, fix gomobile builds
* travis, build: move NDK into its final bundle location
* travis: disable Android build on PRs once again
This change
- implements concurrent LES request serving even for a single peer.
- replaces the request cost estimation method with a cost table based on
benchmarks which gives much more consistent results. Until now the
allowed number of light peers was just a guess which probably contributed
a lot to the fluctuating quality of available service. Everything related
to request cost is implemented in a single object, the 'cost tracker'. It
uses a fixed cost table with a global 'correction factor'. Benchmark code
is included and can be run at any time to adapt costs to low-level
implementation changes.
- reimplements flowcontrol.ClientManager in a cleaner and more efficient
way, with added capabilities: There is now control over bandwidth, which
allows using the flow control parameters for client prioritization.
Target utilization over 100 percent is now supported to model concurrent
request processing. Total serving bandwidth is reduced during block
processing to prevent database contention.
- implements an RPC API for the LES servers allowing server operators to
assign priority bandwidth to certain clients and change prioritized
status even while the client is connected. The new API is meant for
cases where server operators charge for LES using an off-protocol mechanism.
- adds a unit test for the new client manager.
- adds an end-to-end test using the network simulator that tests bandwidth
control functions through the new API.
* swarm/pss: fix data race on HandshakeController.symKeyIndex
The HandshakeController.symKeyIndex map was accessed concurrently.
Since insufficient test coverage the race is not detected every time.
However, running TestClientHandshake a 100 times seems to be enough to
reproduce the race.
Note: I've chosen HandshakeController.lock to protect
HandshakeController.symKeyIndex as that was already protected in a few
functions by that lock.
Additionally:
- removed unused testStore
- enabled tests in handshake_test.go as they pass
- removed code duplication by adding getSymKey()
* swarm/pss: fix a data race on HandshakeController.keyC
* swarm/pss: fix data races with on Pss.symKeyPool
