Tantivy used to assume that all files could be somehow memory mapped. After this change, Directory return a `FileSlice` that can be reduced and eventually read into an `OwnedBytes` object. Long and blocking io operation are still required by they do not span over the entire file.
* add support for indexed bytes fast field
* remove backup code file
* refine test cases
* Simplified unit test. Renamed it as it is testing the storable part. Not the indexed part.
* Small refactoring and added unit test. If multivalued we only retain the first FAST value.

- Change in the DocSet and Scorer API. (@fulmicoton).
A freshly created DocSet point directly to their first doc. A sentinel value called TERMINATED marks the end of a DocSet.
`.advance()` returns the new DocId. `Scorer::skip(target)` has been replaced by `Scorer::seek(target)` and returns the resulting DocId.
As a result, iterating through DocSet now looks as follows
```rust
let mut doc = docset.doc();
while doc != TERMINATED {
// ...
doc = docset.advance();
}
```
The change made it possible to greatly simplify a lot of the docset's code.
- Misc internal optimization and introduction of the `Scorer::for_each_pruning` function. (@fulmicoton)
* Alternative take on boosted queries
* Fixing unit test
* Added boosting to the query grammar.
* Made BoostQuery public.
* Added support for boosting field in QueryParser
Closes#547
* add checksum check in ManagedDirectory
fix#400
* flush after writing checksum
* don't checksum atomic file access and clone managed_paths
* implement a footer storing metadata about a file
this is more of a poc, it require some refactoring into multiple files
`terminate(self)` is implemented, but not used anywhere yet
* address comments and simplify things with new contract
use BitOrder for integer to raw byte conversion
consider atomic write imply atomic read, which might not actually be true
use some indirection to have a boxable terminating writer
* implement TerminatingWrite and make terminate() be called where it should
add dependancy to drop_bomb to help find where terminate() should be called
implement TerminatingWrite for wrapper writers
make tests pass
/!\ some tests seems to pass where they shouldn't
* remove usage of drop_bomb
* fmt
* add test for checksum
* address some review comments
* update changelog
* fmt
* Refactor deletes
* Removing generation from SegmentUpdater. These have been obsolete for a long time
* Number literal clippy
* Removed clippy useless allow statement
