If two `helm upgrade`s are executed at the exact same time, then one of
the invocations will fail with "already exists".
If one `helm upgrade` is executed and a second one is started while the
first is in `pending-upgrade`, then the second invocation will create a
new release. Effectively, two helm invocations will simultaneously
change the state of Kubernetes resources -- which is scary -- then two
releases will be in `deployed` state -- which can cause other issues.
This commit fixes the corrupted storage problem, by introducting a poor
person's lock. If the last release is in a pending state, then helm will
abort. If the last release is in a pending state, due to a previously
killed helm, then the user is expected to do `helm rollback`.

If stat returns an error other than the directory not existing
it was unhandled. When IsDir is called in one of these situations
it causes a panic.

* Fixing issue with PAX headers in plugin archive
PAX Headers can be added by some systems that create archives. Helm
should ignore them when extracting.
There are two PAX headers. One is global and the other is not. Both
are ignored. The test adds only the PAX global header because the
Go tar package is unable to write the header that is not global.

* Removing the PAX header test as it is not working
The PAX header test was making a WriteHeader call and ignoring the
error. When writing the type TypeXHeader it was causing an error
that was being silently ignored. The Go tar package cannot write
this type and produces an error when one tries to. The error reads
"cannot manually encode TypeXHeader, TypeGNULongName, or TypeGNULongLink
headers"
