189ae0c38b util: dedup code in callers of serviceFlagToStr() (Vasil Dimov)
fbacad1880 util: simplify the interface of serviceFlagToStr() (Vasil Dimov)
Pull request description:
Don't take two redundant arguments in `serviceFlagToStr()`.
Introduce `serviceFlagsToStr()` which takes a mask (with more than one
bit set) and returns a vector of strings.
As a side effect this fixes an issue introduced in
https://github.com/bitcoin/bitcoin/pull/18165 due to which the GUI could
print something like `UNKNOWN[1033] & UNKNOWN[1033] & UNKNOWN[2^10]`
instead of `NETWORK & WITNESS`.

96954d1794 DNS seeds: don't query DNS while network is inactive (Anthony Towns)
fa5894f7f5 DNS seeds: wait for 5m instead of 11s if 1000+ peers are known (Anthony Towns)
Pull request description:
Changes the logic for querying DNS seeds: after this PR, if there's less than 1000 entries in addrman, it will still usually query DNS seeds after 11s (unless the first few peers tried mostly succeed), but if there's more than 1000 entries it won't try DNS seeds until 5 minutes have passed without getting multiple outbound peers. (If there's 0 entries in addrman, it will still immediately query the DNS seeds). Additionally, delays querying DNS seeds while the p2p network is not active.

Pull request description:
Side effect: this results in the RPC showing unknown service bits as "UNKNOWN[n]" like the GUI.
Note that there is no common mask-to-`vector<string>` function because both GUI and RPC would need to iterate through it to convert to their desired target formats.

a06e845e82 BlockTip struct created and connected to notifyHeaderTip and notifyBlockTip signals. (furszy)
2f867203b0 Added best block hash to the NotifyHeaderTip and NotifyBlockTip signals. (furszy)
Pull request description:
Rationale:
The height based polling in the GUI is an issue on chain reorgs. Any new tip signal with the same height as the one that it's cached in the model was not triggering the GUI update (interpreting it as the same same block when it could receive a different one). Ending up with bad information presented in the GUI.
This PR essentially changes the last cached height to be a last cached block hash.
---
Old historical information of this PR.
As the tip height is cached and updated via signaling in clientModel, there is no need to continue locking `cs_main` on every balance poll (`m_node.getNumBlocks()` method call).
Extra topic:
Would suggest to change the `cachedNumBlocks` field inside `walletModel` to a more understandable name, maybe `nLastBalanceUpdateHeight`.
And finally, this will have the equal height reorg issue mentioned [here](https://github.com/bitcoin/bitcoin/pull/17905#issuecomment-577324304), whatever is presented to fix it, this should use the same flow too.
**[Edit - 24/01/2020]**

e8fa0a3d20 Fix WSL file locking by using flock instead of fcntl (Samuel Dobson)
Pull request description:
Fixes#18622
A bug in WSL means that fcntl does not exclusively lock files, allowing multiple instances of bitcoin to use the same datadir. If we instead use flock, it works correctly. Passes Travis, but testing on some OS variety would be sensible.
From what I can tell, flock and fcntl don't work with each other on linux, so it would still be possible to run a node with this code change and a node before it with the same datadir (this isn't true for Mac/FreeBSD). flock also doesn't support NFS on MacOS and linux<2.6.12 while fcntl did. See here for example: https://gavv.github.io/articles/file-locks/
If changing to flock for all systems is inadvisable, it would also be possible to just detect WSL and use flock when on that platform to avoid the bug.

Replace with RPC request reference to new WalletContext struct similar to the
existing NodeContext struct and reference.
This PR is a followup to 25ad2c623ahttps://github.com/bitcoin/bitcoin/pull/18740 removing the g_rpc_node global.
Some later PRs will follow this up and move more wallet globals to the
WalletContext struct.

c3cf2f5501 rpc/blockchain.cpp: Remove g_utxosetscan mutex that is only protecting a single atomic variable (Anthony Towns)
Pull request description:
In a few cases we need to use `std::mutex` rather than the sync.h primitives. But `std::lock_guard<std::mutex>` doesn't include the clang thread safety annotations unless you also use clang's C library, which means you can't indicate when variables should be guarded by `std::mutex` mutexes.
This adds an annotated version of `std::lock_guard<std::mutex>` to threadsafety.h to fix that, and modifies places where `std::mutex` is used to take advantage of the annotations.
It's based on top of #16112, and turns the thread safety comments included there into annotations.
It also changes the RAII classes in wallet/wallet.h and rpc/blockchain.cpp to just use the atomic<bool> flag for synchronisation rather than having a mutex that doesn't actually guard anything as well.

We want to supply well-known vars to ./configure scripts to do with as
they please. However, we do _not_ want to override these well-known vars
at make-time as certain build systems expect a self-mangled version of
these well-known vars.
For example, freetype and bdb will prepend `libtool --mode=compile' to
CC and CXX, which, if we override CC on the command line at make-time,
will break the build.
Previously, we specified the target-os in the toolset (and sometimes
used the wrong command line flags), now we have a clear separation,
which is favored by ./bootstrap.sh and ./b2.
This means that all supported OSes will specify the correct target-os=
and toolset= on the command line.
b2 will pickup our user-config.jam just fine, however, bootstrap.sh has
its own toolset autodetect mechanism, which doesn't GAF about our
user-config.jam
c57f03ce17 refactor: Replace const char* to std::string (Calvin Kim)
Pull request description:
Rationale: Addresses #19000
Some functions should be returning std::string instead of const char*.
This commit changes that.
Main benefits/reasoning:
1. The functions never return nullptr, so returning a string makes code at call sites easier to review (reviewers don't have to read the source code to verify that a nullptr is never returned)
2. All call sites convert to string anyway
