Clean less keys by tracking the two cases:
* Touched keys per slot in uncleaned_keys derived from
accounts delta hash operation.
* Set of keys with any zero-lamport updates.
* Simpler cap by including sysvars and native programs
* Fix tests
* Add comment
* revert some unrelated code
* Update test_bank_update_sysvar_account for cap.
* Test cap. for add_native_program using new helper
* Improve the cap adjustment with new tests
* Fix typo...
* Adjust test for improved code coverage
* Rename simpler_capitalization => simple_capitalization
* More rename and bonus commenting
* Re-use accounts_db stores
Creating files and dropping mmap areas can be expensive
* Add test for storage finder
Can encounter an infinite loop when the store is too small, but
smaller than the normal store size.
* Fix storage finding
* Check for strong_count == 1
* try_recycle helper
* Check bank capitalization
* Simplify and unify capitalization calculation
* Improve and add tests
* Avoid overflow and inhibit automatic restart
* Fix test
* Tweak checked sum for cap. and add tests
* Fix broken build after merge conflicts..
* Rename to ClusterType
* Rename confusing method
* Clarify comment
* Verify cap. in rent and inflation tests

Address some clippy complaints.
* Muzzle clippy type complexity warning.
Despite clippy's suggestion, it is not currently possible to create type aliases
for traits and so everything within the 'Box<...>' cannot be type aliased.
This then leaves creating full blown traits, and either implementing
said traits by closure (somehow) or moving the closures into new structs
implementing said traits which seems a bit of a palaver.
Alternatively it is possible to define and use the type alias 'type ResultBox<T> = Result<Box<T>>'
which does seems rather pointless and not a great reduction in complexity but is enough to keep clippy happy.
In the end I simply went with squelching the clippy warning.
