Panic if we insert invalid branchResult into the cache.

Should provide more data for bug #109.

Ensure all.bash tests compilation on both Darwin and Linux.

Fixes #125.

This makes it evident which tests leak mount points.

Move shared test utilities into internal/testutil/ package.

This is less overhead, and fixes the darwin tests that use InitIn.

Fixed handling of ENOSYS in unionfs.

When mounting using relative paths, "touch" on directories
used to fail.

"touch" on files works accidentially because it uses a
file descriptor internally.

  $ loopback b a &
  $ cd b
  $ mkdir foo
  $ touch foo
  touch: setting times of 'foo': Not a directory

strace:

  [pid 30185] utimensat(0, "a/foo", [{1468441847, 0}, {1468441847, 0}], AT_SYMLINK_NOFOLLOW <unfinished ...>
  [pid 30185] <... utimensat resumed> )   = -1 ENOTDIR (Not a directory)

On Mac OS X the Finder loses its mind if GetXAttr returns ENODATA
rather than ENOATTR. On Linux, ENOATTR is just an alias for ENOATTR.

The Linux man page references ENOATTR:
http://man7.org/linux/man-pages/man2/fgetxattr.2.html

Gerrithub requires overly broad write permissions, and hence its usage
is discontinued.

Add AUTHORS file.

This makes CFuse and go-fuse easier to compare.  Get rid of the
baroque analysis code, unused delay code, and some general cleanup.

Surpress benchmark if -v is not given.

The strategy was inspired by the mount code for Darwin in
bazil.org/fuse.

Unfortunately, OSX must have the event loop started before mounting
can be completed. This means that WaitMount() must be maintained for
use on OSX.

This ensures that the caller can access fsConnector.Server(), eg. to
inspect the InitRequest or InitResponse.

SetDebug methods are maintained for compatibility.

This is part of a patch series to process the INIT opcode on
mount. This will enable filesystems to switch functionality depending
on kernel settings.

In order to get the debug output for the INIT opcode, the debug option
must be passed to the mount method.

Deprecate the SetDebug methods. There is often little practical use in
toggling debug on the fly, since the error scenarios depend on timing
details, and must usually be isolated into unittests.

Any node that returns ENOSYS for Getxattr will cause the kernel to
stop issuing Getxattr calls altogether. In file systems that must
support GetXAttr and that has multiple node types, tracking down all
node types and overriding GetXAttr for them individually is annoying.

For filesystems that need the performance benefit of skipping GETXATTR
calls, provide a DisableXAttrs option.
