* sdk: Add concurrent support for rand 0.7 and 0.8
* Update rand, rand_chacha, and getrandom versions
* Run command to replace `gen_range`
Run `git grep -l gen_range | xargs sed -i'' -e 's/gen_range(\(\S*\), /gen_range(\1../'
* sdk: Fix users of older `gen_range`
* Replace `hash::new_rand` with `hash::new_with_thread_rng`
Run:
```
git grep -l hash::new_rand | xargs sed -i'' -e 's/hash::new_rand([^)]*/hash::new_with_thread_rng(/'
```

The callstack updated in this PR passed an &Arc<...> down only to have
the bottom level clone the reference. Thus, we are giving shared
ownership so the reference is a bit redundant and arguably obscures the
intention to clone further down the callstack.
#### Problem
AccountsFile- and AppendVec-related code uses io::Error for their main error type. However, there're many errors under AccountsFile that don't belong to io::Error.
#### Summary of Changes
This PR introduces AccountsFileError and makes minimum changes to keep the PR small.
Subsequent changes related to this will be in separate PRs.
* Remove snapshot_links
* Change the function name from snapshot_dir to bank_snapshot_dir
* Format fix
* Fix test_concurrent_snapshot_packaging
* Fix clippy error
* Fix nits
* Fix nits 2nd try
* Use get_bank_snapshots_dir
* Use slot_dir
* Revert "Use get_bank_snapshots_dir" because get_bank_snapshots_dir is private to crate
This reverts commit 1ed9b3b2c8e84689a918beee7159f63c56500a96.
#### Problem
Accounts db currently use AppendVec::new_from_file() directly
to create a new AcountsFile instance from an existing file.
However, this method should be abstracted out to AccountsFile
so that an existing file can be opened correctly using the right format.
#### Summary of Changes
Add new_from_file() API to AccountsFile which will open an existing
file based on its accounts file format.
Currently, it only supports AppendVec.
