Harshavardhana d864e00e24 posix: Deprecate custom removeAll/mkdirAll implementations. (#4808)
Since go1.8 os.RemoveAll and os.MkdirAll both support long
path names i.e UNC path on windows. The code we are carrying
was directly borrowed from `pkg/os` package and doesn't need
to be in our repo anymore. As a side affect this also
addresses our codecoverage issue.

Brendan Ashworth bccc386994 fs: drop Stat() call from fsDeleteFile,deleteFile (#4744)
This commit makes fsDeleteFile() simply call deleteFile() after calling
the relevant path length checking functions. This DRYs the code base.

This commit removes the Stat() call from deleteFile(). This improves
performance and removes any possibility of a race condition.

This additionally adds tests and a benchmark for said function. The
results aren't very consistent, although I'd expect this commit to make
it faster.

Harshavardhana 075b8903d7 fs: Add safe locking semantics for `format.json` (#4523)
This patch also reverts previous changes which were
merged for migration to the newer disk format. We will
be bringing these changes in subsequent releases. But
we wish to add protection in this release such that
future release migrations are protected.

Revert "fs: Migration should handle bucketConfigs as regular objects. (#4482)"
This reverts commit 976870a391.

Revert "fs: Migrate object metadata to objects directory. (#4195)"

Harshavardhana 976870a391 fs: Migration should handle bucketConfigs as regular objects. (#4482)
Current code failed to anticipate the existence of files
which could have been created to corrupt the namespace such
as `policy.json` file created at the bucket top level.

In the current release creating such as file conflicts
with the namespace for future bucket policy operations.
We implemented migration of backend format to avoid situations
such as these.

This PR handles this situation, makes sure that the
erroneous files should have been moved properly.

Harshavardhana f0b5c0ec7c windows: Support all REPARSE_POINT attrib files properly. (#4203)
This change adopts the upstream fix in this regard at
https://go-review.googlesource.com/#/c/41834/ for Minio's
purposes.

Go's current os.Stat() lacks support for lot of strange
windows files such as

 - share symlinks on SMB2
 - symlinks on docker nanoserver
 - de-duplicated files on NTFS de-duplicated volume.

This PR attempts to incorporate the change mentioned here

   https://blogs.msdn.microsoft.com/oldnewthing/20100212-00/?p=14963/

The article suggests to use Windows I/O manager to
dereference the symbolic link.
