Add the infrastructure for btime support in the form of a new STATX
request.

The format of the STATX reply is binary compatible with struct statx on
Linux, but the structure is defined separately in the fuse API for other
OS's.

Currently STATX only supports basic attributes, same as the GETATTR
request, plus btime.  But nothing prevents extending support to other
(present and future) statx fields.
