7a53215a57 No longer return &str for short names in no_std mode 
Instead methods returning &[u8] were added.
It is API preparation for proper OEM codepage decoding.
Previous behavior would require to store duplicated short names
(one lossy and one real).

8c1dae9f0c Do not remove source file in Dir::rename if destination already exists 
Previous code removed source file before returning an error.
It also caused a clusters leak. Now it returns error before doing any
modifications on the partition.

4afd38a150 Fix possible overflow when calculating short name checksum 
Affects debug build only. Overflow was not handled when calculating
checksum used for short name generation when avoiding a conflict.
LFN checksum was working properly but got refactored in this commit to
use num::Wrapping as well.

217b6046f1 Make disk object type generic (breaking change) 
This change allows for moving an object ownership to FileSystem object
instead of borrowing it. It makes usage of library easier in some cases.
Unfortunately it is a breaking change.

2304b13ec4 Take immutable self reference in Dir methods 
Dir methods do not change Dir object itself. They usually clone inner
stream so no change really happens self struct. Underlying partition is
modified but it does not have to affect API. For example see
std::fs::File::set_len. This change greatly simplifies rename API usage.

18b9d8c285 Do not panic if unexpected file type is found during path traversal 
For example if in the middle of the path a file is found.
Return error in such case instead of panicking.
