As the libsecp256k1 context was only initialized in the TestingSetup, we have been forced to use it when sometimes it is not necessary (TestingSetup is a complete setup that includes CConnman, scheduler, validation interface, etc).

This commit attempts to clarify and correct the `-blocksdir` argument description and default value. `-blocksdir` does not refer to the full path to the actual `blocks` directory, but rather the root/parent directory which contains the `blocks` directory. Accordingly, the default value is `<datadir>` and not `<datadir>/blocks`. It also attempts to clarify that only the `.dat` files containing block data are impacted by `-blocksdir`, not the index files.
The blocks directory is net specific by definition. Also this prevents the side effect of calling GetBlocksDir(false) in the non-mainnet environment.
A new node should not create an unused `blocks` directory in the root of the data directory when `-testnet` or `-regtest` is specified.
Rather than both. Introduced in 386a6b6
This commit does not change behavior as GetBlocksDir() with unset "-blocksdir" returns the same path.
Use case: TryCreateDirectory(GetDataDir() / "blocks" / "index") would fail if the blocks directory was not explicitly created before. The line that did so was in a weird location and could be removed as a result.

updated, typos corrected. |

functionally good. might as well document the new option in the release notes template here so it doesn't need to be done later |

Updated per feedback, added |

(Jim Posen) e65acf0 util: Move CheckDiskSpace to util. (Jim Posen) Pull request description: This is part of the block logic refactoring and encapsulation work coming from upstream (work started in #2326 and #2328 due the possible blocks db corruption issue). Needed for two future works: (1) faster block validation using a new cache structure and (2) the future possible custom BIP157 (new sync protocol that supersedes BIP37 for light clients -- pending research needed after finishing v6.0 priorities --) Essentially, it's encapsulating the sequenced files open/read/write functionalities inside a new `flatfile` module, and extending the unit test coverage to validate its correct behavior. Adapted the following PRs: * bitcoin#15118. * bitcoin#13145. * Plus added `util.h/cpp` files mv to `util/system.h` & `util/system.cpp`.

Grouped two different, zero risk, modifications here to not have to create two/three small and straightforward PRs:
1) Unit Tests:
BasicTestingSetupreceiving the network in the constructor.2) Back ported the ability to specify a custom directory for the blocks storage.
