- Extend the size of the FUSE_INIT request to accommodate for more
flags. There's a slight possibility of a regression for obscure fuse
servers; if this happens, then more complexity will need to be added
to the protocol

basis in virtiofs

fuse: send security context of inode on file

When a new inode is created, send its security context to server along with
creation request (FUSE_CREAT, FUSE_MKNOD, FUSE_MKDIR and FUSE_SYMLINK).
This gives server an opportunity to create new file and set security
context (possibly atomically). In all the configurations it might not be
possible to set context atomically.

Like nfs and ceph, use security_dentry_init_security() to dermine security
context of inode and send it with create, mkdir, mknod, and symlink
requests.

Following is the information sent to server.

fuse_sectx_header, fuse_secctx, xattr_name, security_context

- struct fuse_secctx_header
This contains total number of security contexts being sent and total
size of all the security contexts (including size of
fuse_secctx_header).

- struct fuse_secctx
This contains size of security context which follows this structure.
There is one fuse_secctx instance per security context.

- xattr name string
This string represents name of xattr which should be used while setting
security context.

- security context
This is the actual security context whose size is specified in
fuse_secctx struct.

Also add the FUSE_SECURITY_CTX flag for the `flags` field of the
fuse_init_out struct. When this flag is set the kernel will append the
security context for a newly created inode to the request (create, mkdir,
mknod, and symlink). The server is responsible for ensuring that the inode
appears atomically (preferrably) with the requested security context.

For example, If the server is using SELinux and backed by a "real" linux
file system that supports extended attributes it can write the security
context value to /proc/thread-self/attr/fscreate before making the syscall
to create the inode.

This patch is based on patch from Chirantan Ekbote <chirantan@chromium.org>

fuse: only update necessary attributes

fuse_update_attributes() refreshes metadata for internal use.

Each use needs a particular set of attributes to be refreshed, but
currently that cannot be expressed and all but atime are refreshed.

Add a mask argument, which lets fuse_update_get_attr() to decide based on
the cache_mask and the inval_mask whether a GETATTR call is needed or not.

fuse: add cache_mask

If writeback_cache is enabled, then the size, mtime and ctime attributes of
regular files are always valid in the kernel's cache. They are retrieved
from userspace only when the inode is freshly looked up.

Add a more generic "cache_mask", that indicates which attributes are
currently valid in cache.

This patch doesn't change behavior.

fuse: move reverting attributes to fuse_change_attributes()

In case of writeback_cache fuse_fillattr() would revert the queried
attributes to the cached version.

Move this to fuse_change_attributes() in order to manage the writeback
logic in a central helper. This will be necessary for patches that follow.

Only fuse_do_getattr() -> fuse_fillattr() uses the attributes after calling
fuse_change_attributes(), so this should not change behavior.

Incrementing the nlink will result in the wrong count. This wasn't noticed
because the attributes were invalidated right after this.

Updating ctime is still needed for the writeback case when the ctime is not
