fc2f0023a0 messaging: Remove the "n_sent" arg from message_send_all
The only user of this is an informative message in smbcontrol. I don't think
that's worth the effort.

f396449e7a lib: Move "message_send_all" to serverid.c
Trying to trim down messages.c a bit: Sending to all processes that are
registered in serverid.tdb and filtering to me is not really logic of general
messaging but more of the serverid code.

42468bcb40 fssd: include config.h before any glibc headers
config.h may have some flags which affect glibc behavior, e.g.
_FILE_OFFSET_BITS=64. To make sure these flags have the desired
effect, config.h must be included before any glibc header files.

This commit does not fix a specific known bug. It changes the code to
comply with coding conventions.

7a38f148ac fsrvp: prune shadow copies if associated path doesn't exist
This patch implements some simple FSRVP server housekeeping. On startup
the server scans the cached entries, any entries where the underlying
system paths associated with shadow copies no longer exist are removed
from the cache and from the registry.

This behaviour is disabled by default, but can be enabled via the new
"fss: prune stale" smb.conf parameter.

b6e034069f fsrvp: add remote snapshot RPC server
The Samba fss_agent RPC server is an implementation of the File Server
Remote VSS (Volume Shadow Copy Service) Protocol, or FSRVP for short.

FSRVP is new with Windows Server 2012, and allows authenticated clients
to remotely request the creation, exposure and deletion of share
snapshots.

The fss_agent RPC server processes requests on the FssAgentRpc named
pipe, and dispatches relevant snapshot creation and deletion requests
through to the VFS.
The registry smb.conf back-end is used to expose snapshot shares, with
configuration parameters and share ACLs cloned from the base share.

There are three FSRVP client implementations that I'm aware of:
- Samba rpcclient includes fss_X commands.
- Windows Server 2012 includes diskshadow.exe.
- System Center 2012.

FSRVP operations are only processed for users with:
- Built-in Administrators group membership, or
- Built-in Backup Operators group membership, or
- Backup Operator privileges, or
- Security token matches the initial process UID

MS-FSRVP specifies that server state should be stored persistently
during operation and retrieved on startup. Use the existing fss_srv.tdb
FSRVP state storage back-end to satisfy this requirement.

9c8ae4454c fsrvp: add server state storage back-end
MS-FSRVP specifies:
  the server MUST persist all state information into an implementation-
  specific configuration store.

This change adds a fss_srv TDB database to preserve FSRVP server state,
with the following keys used to track shadow copy state and hierarchy:
- sc_set/<shadow copy set GUID>
  A shadow copy set tracks a collection of zero or more shadow copies,
  as initiated by a StartShadowCopySet FSRVP client request.
- sc_set/<shadow copy set GUID>/sc/<shadow copy GUID>
  A shadow copy defines information about a snapshot base volume, the
  snapshot path, and a collection of share maps. It is initiated by an
  AddToShadowCopySet client request.
- sc_set/<shadow copy set GUID>/sc/<shadow copy GUID>/smap/<smap GUID>
  A share map tracks new shares that are created to expose shadow
  copies.

All structures are marshalled into on-disk format using the previously
added fsrvp_state IDL library.
