be8ab7d08 Create new wallet databases as directories rather than files (Russell Yanofsky)
26c06f24e Allow wallet files not in -walletdir directory (Russell Yanofsky)
d8a99f65e Allow wallet files in multiple directories (Russell Yanofsky)
Pull request description:
This change consists of three commits:
* The first commit is a pure refactoring that removes the restriction that two wallets can only be opened at the same time if they are contained in the same directory.
* The second commit removes the restriction that `-wallet` filenames can only refer to files in the `-walletdir` directory.
* The third commit makes second commit a little safer by changing bitcoin to create wallet databases as directories rather than files, so they can be safely backed up.
All three commits should be straightforward:
* The first commit adds around 20 lines of new code and then updates a bunch of function signatures (generally updating them to take plain fs::path parameters, instead of combinations of strings, fs::paths, and objects like CDBEnv and CWalletDBWrapper).
* The second commit removes two `-wallet` filename checks and adds some test cases to the multiwallet unit test.
* The third commit just changes the mapping from specified wallet paths to bdb environment & data paths.

**Note:** For anybody looking at this PR for the first time, I think you can skip the comments before _20 Nov_ and start reading at https://github.com/bitcoin/bitcoin/pull/11687#issuecomment-345625565. Comments before _20 Nov_ were about an earlier version of the PR that didn't include the third commit, and then confusion from not seeing the first commit.

be9a13c Add configuration/argument testing (MeshCollider)
Pull request description:
Adds a new functional test for testing various command line and configuration file argument interactions, that aren't specific enough to other functionality to be placed in other tests.
Currently this tests the error messages for non-existent datadir, which would have caught the bug fixed in https://github.com/bitcoin/bitcoin/pull/11829. It also tests that command line arguments override the ones in the config file.
I plan on working on a fix for https://github.com/bitcoin/bitcoin/issues/11819 / https://github.com/bitcoin/bitcoin/issues/1044 and then expanding this test with cases for that.
