75c5916dde Release lock during WriteStream for inmemory driver
While reading from the input in WriteStream, the inmemory driver can deadlock
if the reader is from the same instance. To fix this, the write lock is
released before reading into a local buffer. The lock is re-acquired to
finish the actual write.

a2b294f444 Add the URLFor optional method to the storagedriver api
We now also have a storagedriver error variable for identifying
api calls that are not implemented by drivers (the URLFor method
is not implemented by either the filesystem or inmemory drivers)

f6aadc2028 Relaxes storagedriver path constraints (#47)
No longer requires that file paths match the repository naming scheme,
but instead allows path components as short as a single character, as to
accommodate for single-character tag names.

3178d8cfad Add a README file and make encrypt and rootdirectory optional parameters.
Note that the README currently contains details about the secure parameter which is part of a
separate pull request. I feel confident adding it here since I am certain we will eventually add
the secure parameter. Also note that encrypt now defaults to true and rootdirectory defaults to
the empty string.

8ca960a0b5 S3 driver refactor
This requires some discussion of how we will handle errors due to network problems
and after further changes in that direction some more stress testing. There is also an
upcomming commit implementing zero fill on WriteStream when offset is greater than
the current size of the file.

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.

f57e544919 Increases stress test factor of TestConcurrentFileStreams

without the Short flag

8cb0e3398c Disable s3, azure and ipc packages and testing
The packages causing build errors are being disabled for now to let us split up
the work in the different driver implementations without blocking integration
into the main branch. The s3 and azure implementations need some effort to add
Stat support. The ipc package needs that work plus some care around hanging
send calls.

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.

ab9570f872 Migrate filesystem driver to new storagedriver calls
The filesystem driver has been migrated to impleemnt the storagedriver
interface changes. Most interetingly, this provides a filesystem-based
implementation of the Stat driver call. With this comes some refactoring of
Reads and Write to be much simpler and more robust.

The IPC tests have been disabled to stability problems that we'll have to
troubleshoot at a later date.

2037b1d6bf Update testsuite with storagedriver interface changes
This change updates the testsuite to migrate to the new driver interface. This
includes the new Stat call, changes to int64 over uint64 and the changes to the
WriteStream signature. Several test cases have been added to vet
implementations against various assumptions.

2e3ecdca37 Remove size argument and using io.Reader for StorageDriver.WriteStream
We are change the the rpc call for WriteStream to not require the size
argument, opting to drive the process with io.Reader. The main issue was that
io.Reader may return io.EOF before reaching size, making the error handling
around this condition for callers more complex. To complement this, WriteStream
now returns the number of successfully written bytes.

The method no longer requires an io.ReadCloser, opting to require just an
io.Reader. This keeps the reader under the control of the caller, which
provides more flexibility.

This also begins to address some of the problems described in #791.

ac660e72bf Replace StorageLayer.CurrentSize interface call with Stat
To support single-flight Size and ModTime queries against backend storage file,
we are replacing the CurrentSize call with a Stat call. A FileInfo interface is
provided for backends to provide a type, with a default implementation called
FileInfoInternal, for use by driver implementations.

More work needs to follow this change to update all the driver implementations.

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.
