8a1889efeb Enforces a path format for storage drivers (#819)
Requires all paths in the inmemory and filesystem drivers to begin with
a slash, and then contain only valid path components (2+ alphanumeric
characters with optional period, hyphen, and underscore separators)
delimited by slashes.

Also updates the storage driver test suites to construct paths of this
format, and causes the suite to abort if files are not cleaned up after
the test run.

94052ea213 Fixes normalization of inmemory file paths
A normalized path always begins with "/" and never has a trailing slash
unless it is the root directory.

cacf33ab62 Uses random paths with slashes for storagedriver tests, adds edge cases
This replaces only using flat filenames, to better test nested file
behaviors.
Fixed inmemory/mfs.go and filesystem/driver.go after finding bugs with
the new tests and test behavior.

d703a86a64 Add checks for ReadStream offset boundary conditions
Several checks for ReadStream with offset around boundary conditions were
missing. The new checks ensure negative offsets are detected and io.EOF is
returned properly when trying to read past the end of a file. The filesystem
and inmemory driver have been updated accordingly.

An outline of missing checks for List are also part of this commit. Action will
be taken here based on discussion in issue #819.

2ebc373d91 Refactor inmemory driver for Stat and WriteStream methods
This change started out as simply updating the existing inmemory driver to
implement the new Stat call. After struggling with the map based
implementation, it has been refactored to be a tree-based implementation.

This process has exposed a few missing error cases in the StorageDriver API
that should be addressed in the coming weeks.

66107df1af Use int64 for ReadStream and WriteStream offsets
This change brings the storagedriver API in line with the Go standard library's
use of int64 for offsets. The main benefit is simplicity in interfacing with
the io library reducing the number of type conversions in simple code.

ca0084fad1 Adds StorageDriverFactory, unifying creation of StorageDrivers
Custom storage drivers can register a factory to create the driver by
name, similar to the database/sql package's Register and Open
factory.Create returns an in-process driver if registered or an IPC
driver if one can be found, erroring otherwise
This standardizes parameter passing for creation of storage drivers

Also adds documentation for storagedriver package and children
