* XL/erasure-read: optimize memory allocation during erasure-read by using temporary buffer pool.
With the change the buffer needed during GetObject by erasureReadFile is allocated only once.
Change brings in a new signVerifyReader which provides a io.Reader
compatible reader, additionally implements Verify() function.
Verify() function validates the signature present in the incoming
request. This approach is choosen to avoid complexities involved
in using io.Pipe().
Thanks to Krishna for his inputs on this.

Previously checkDiskFree() checks for free available space. This
patch enables checkDiskFree() also checks for free inodes in linux and
free clusters in windows.
Fixes#2075
The object cache implementation is XL cache, which defaults
to 8GB worth of read cache. Currently GetObject() transparently
writes to this cache upon first client read and then subsequently
serves reads from the same cache.
Currently expiration is not implemented.
Some environments might disable access to `/dev/tty`, fall
back to '80' in such scenarios.
Move to 'cheggaaa/pb' package for better cross platform
support on fetching terminal width.

The functionality provided by minhttp will be implemented
cleanly through our own APIs. Since we are not going to
send SIGUSR2 and manage configuration in that manner, it
doesn't make sense to use minhttp.

Signature calculation has now moved out from being a package to
top-level as a layered mechanism.
In case of payload calculation with body, go-routines are initiated
to simultaneously write and calculate shasum. Errors are sent
over the writer so that the lower layer removes the temporary files
properly.
Optimizing List Objects by using binary sort to discard entries in cases
where prefix or marker is set.
Adding test coverage to ListObjects.
Adding benchmark to ListObjects.
In the common case, GetObject is called on a bucket that exists and an
object that exists and is not a directory. It should be optimized for
this case, thus error-related syscalls are pushed back until they are
necessary.
This should not impact performance negatively in the uncommon case, and
instead drops two otherwise unnecessary os.Stat's in the common case.
The race conditions around a proper error being returned were present
beforehand.
It also renames 'err' to 'e'.
When list object is invoked, it creates a goroutine if not available
for given parameters else uses existing goroutine. These goroutines
are alive for 15 seconds for further continuation list object request
else they exit.
Fixes#1076
This commit improves the docs for both functions (more Go-like) and
drops an unnecessary condition in IsValidBucketName. This also drops a
condition in IsValidObjectName where "" (empty string) was a valid
object name. This has been fixed and will no longer return true.
This commit also adds tests for both functions, including a regression
test for the bug fix.
There is now a simple test and a benchmark for ListBuckets. I also
dropped an unnecessary check that was simply repeated from above,
guaranteed to be true.
It had a lot of code that was the same as GetBucketMetadata, so instead
call GBM from SBM so as to reduce doing the same thing in two different
spots. Theoretically this will induce a small overhead as now at least
two calls of denormalizeBucket are made, although this shouldn't be
noticeable.
This commit prefers the use of 'defer' for fs.Unlock (and fs.RUnlock)
because it is more idiomatic Go and reduces repetition in the code,
lending to a cleaner code base.
It also switches a few uses of the lock to read-only locks, which should
improve performance of those functions dramatically in certain contexts.
This API takes input XML input in following form.
```
<?xml version="1.0" encoding="UTF-8"?>
<Delete>
<Quiet>true</Quiet>
<Object>
<Key>Key</Key>
</Object>
<Object>
<Key>Key</Key>
</Object>
...
</Delete>
```
and responds the list of successful deletes, list of errors
for all the deleted objects.
```
<?xml version="1.0" encoding="UTF-8"?>
<DeleteResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<Deleted>
<Key>sample1.txt</Key>
</Deleted>
<Error>
<Key>sample2.txt</Key>
<Code>AccessDenied</Code>
<Message>Access Denied</Message>
</Error>
</DeleteResult>
```
