On macOS, pidof installed via brew returns b'' rather than None. Account for this, to remove spurious warnings from the test_runner.

It also adds a convenience script for generating and verifying snapshots at a certain height, since that requires doing a hacky rewind of the chain via `invalidateblock`. All of this is unused at the moment.

Wallets created with `createwallet` can have a `disable_private_keys` parameter, for those wallets we already know that they are watchonly, so there's no reason to have to explicitly ask for it for every command. Instead we check this wallet flag when the `include_watchonly` parameter isn't set.

f13ad1cae0 modify test for memory locked in case locking pages failed at some point (Adam Jonas) 2fa85ebd1c add rpc_misc.py, mv test getmemoryinfo, add test mallocinfo (Adam Jonas) Pull request description: Creating the `rpc_misc.py` functional test file to add space for adding tests to a file that doesn't have a lot of coverage. - Removing the `getmemoryinfo()` smoke test from wallet basic rather than moving it to keep the wallet decoupled. Feel like testing for reasonable memory allocation values should suffice. - Adding coverage for `mallocinfo()`. Introduced standard lib XML parser since the function exports an XML string that describes the current state of the memory-allocation implementation in the caller.

7687f7873 [wallet] Support creating a blank wallet (Andrew Chow) Pull request description: Alternative (kind of) to #14938 This PR adds a `blank` parameter to the `createwallet` RPC to create a wallet that has no private keys initially. `sethdseed` can then be used to make a clean wallet with a custom seed. `encryptwallet` can also be used to make a wallet that is born encrypted. Instead of changing the version number as done in #14938, a wallet flag is used to indicate that the wallet should be blank. This flag is set at creation, and then unset when the wallet is no longer blank. A wallet becomes non-blank when a HD seed is set or anything is imported. The main change to create a blank wallet is primarily taken from #14938. Also with this, the term "blank wallet" is used instead of "empty wallet" to avoid confusion with wallets that have balance which would also be referred to as "empty". This is built on top of #15225 in order to fix GUI issues.

2019-02-10[wallet] Support creating a blank walletAndrew Chow
A blank wallet is a wallet that has no keys, script or watch only things. A new wallet flag indicating that it is blank will be set when the wallet is blank. Once it is no longer blank (a seed has been generated, keys or scripts imported, etc), the flag will be unset.
