06bcdb8 Convert named argument from nblocks to conf_target (Alex Morcos)
439c4e8 Improve api to estimatesmartfee (Alex Morcos)

Pull request description:

  Through 0.14 branch, the estimatesmartfee API was tagged "WARNING: This interface is unstable and may disappear or change!" and this warning is removed for 0.15, so any wanted API updates should happen now.

  The changes here are to make the additional parameter for conservative estimates a more general estimate_mode string , to omit the feerate and include an error string instead of returning -1 on error, and to do better parameter checking initially.

  ~It is only the last 2 commits, but it's built on #10706 and #10543~.

  See #10707 (comment) for renaming of nblocks argument to conf_target.  Will need to be included before string freeze.

8276e70 Adding assert to avoid a memory access violation inside of PartialMerkleTree::CalcHash() (Chris Stewart)

Pull request description:

  Fixing a possible memory access violation in CPartialMerkleTree::CalcHash().

  This can happen if we some how a merkle tree with zero txids. I don't think this can happen in practice as we only send merkle block messages on the p2p network as of now -- we cannot receive them.

  This was found with #8469, specifically using this [generator](https://github.com/Christewart/bitcoin/blob/rapidcheck/src/test/gen/merkleblock_gen.h#L52-L77) which will cause a memory access violation on [this test case](https://github.com/Christewart/bitcoin/blob/rapidcheck/src/test/merkleblock_properties.cpp#L48).

6835cb0 Avoid static analyzer warnings regarding uninitialized arguments (practicalswift)

Pull request description:

  Avoid static analyzer warnings regarding _"Function call argument is a pointer to uninitialized value"_ in cases where we are intentionally using such arguments.

  This is achieved by using `f(b.begin(), b.end())` (`std::array<char, N>`) instead of `f(b, b + N)` (`char b[N]`).

  Rationale:
  * Reduce false positives by guiding static analyzers regarding our intentions.

  Before this commit:

  ```shell
  $ clang-tidy-3.5 -checks=* src/bench/base58.cpp
  bench/base58.cpp:23:9: warning: Function call argument is a pointer to uninitialized value [clang-analyzer-core.CallAndMessage]
          EncodeBase58(b, b + 32);
          ^
  $ clang-tidy-3.5 -checks=* src/bench/verify_script.cpp
  bench/verify_script.cpp:59:5: warning: Function call argument is a pointer to uninitialized value [clang-analyzer-core.CallAndMessage]
      key.Set(vchKey, vchKey + 32, false);
      ^
  $
  ```

  After this commit:

  ```shell
  $ clang-tidy-3.5 -checks=* src/bench/base58.cpp
  $ clang-tidy-3.5 -checks=* src/bench/verify_script.cpp
  $
  ```

912da1d Use AC_ARG_VAR to set ARFLAGS. (René Nyffenegger)

Pull request description:

  Override the default of ARFLAGS of `cru` to `cr`.

  When building, ar produces a warning for each archive, for example
  ```
    AR       libbitcoin_server.a
  /usr/bin/ar: `u' modifier ignored since `D' is the default (see `U')

  ```
  Since `u` is the default anyway, it cannot hurt to remove it.

…ed with square brackets


5c64324 [utils] allow square brackets for ipv6 addresses in bitcoin-cli (John Newbery)
fe4faba [refactor] move SplitHostPort() into utilstrencodings (John Newbery)

Pull request description:

  bitcoin-cli's `-rpcconnect` can accept ipv6 addresses (as long as the libevent version is new enough), but fails to parse ipv6 with square brackets. This PR makes `bitcoin-cli` parse ipv6 in square brackets correctly.

  `bitcoin-cli -rpcconnect=[::1] <command>`

  should now be equivalent to

  `bitcoin-cli -rpcconnect=::1 <command>`

  This is useful so the `bitcoin-cli` option can now be in the same format as the `bitcoind` option.

  Doesn't include tests. I have a branch that fully tests `bitcoin-cli`, but that's queued behind several intermediate PRs.

  - first commit moves `SplitHostPort()` from libbitcoin_common into libbitcoin_util
  - second commit adds proper ipv6 parsing to bitcoin-cli

This removes the possibility for GetCoin/HaveCoin/HaveCoinInCache to return
true while the respective coin is spent. By doing it across all calls, some
extra checks can be eliminated.

coins_tests is modified to call HaveCoin sometimes before and sometimes
after AccessCoin. A further change is needed because the semantics for
GetCoin slightly changed, causing a pruned entry in the parent cache to not
be pulled into the child in FetchCoin.
