46e8e0cd7e lib: Add g_lock_watch_data_send/recv()
Same concept as dbwrap_watched_watch_send/recv: Get informed if the
underlying data of a record changes. This utilizes the watched
database that g_lock is based upon anyway. To avoid spurious wakeups
by pure g_lock operations this patch adds a sequence number for the
data that is stored in the g_lock data field.

b74653f2cd smbd: add twrp arg to synthetic_smb_fname()
Most places take twrp from a local struct smb_filename variable that the
function is working on. Some don't for various reasons:

o synthetic_smb_fname_split() is only called in very few places where we don't
  expect twrp paths

o implementations of SMB_VFS_GETWD(), SMB_VFS_FS_CAPABILITIES() and
  SMB_VFS_REALPATH() return the systems view of cwd and realpath without twrp info

o VFS modules implementing previous-versions support (vfs_ceph_snapshots,
  vfs_shadow_copy2, vfs_snapper) synthesize raw paths that are passed to VFS NEXT
  functions and therefor do not use twrp

o vfs_fruit: macOS doesn't support VSS

o vfs_recycle: in recycle_create_dir() we need a raw OS path to create a directory

o vfs_virusfilter: a few places where we need raw OS paths

o vfs_xattr_tdb: needs a raw OS path for SMB_VFS_NEXT_STAT()

o printing and rpc server: don't support VSS

o vfs_default_durable_reconnect: no Durable Handles on VSS handles, this might
  be enhances in the future. No idea if Windows supports this.

o get_real_filename_full_scan: hm.... FIXME??

o get_original_lcomp: working on a raw path

o msdfs: doesn't support VSS

o vfs_get_ntquota: synthesizes an smb_filename from ".", so doesn't support VSS
  even though VFS modules implement it

o fd_open: conn_rootdir_fname is a raw path

o msg_file_was_renamed: obvious

o open_np_file: pipes don't support VSS

o Python bindings: get's a raw path from the caller

o set_conn_connectpath: raw path

o set_conn_connectpath: raw path

o torture: gets raw paths from the caller

f7fe6fa550 lib/util/fault.c: Unify printing of the stack trace with the INTERNAL ERROR string
We can diverged into the s3 and lib/fault panic action stuff once
we have printed the backtrace.

Our tests require we use the word PANIC, and some administrative scripts
might look for similar things, so keep those words.

The use of DEBUG(0, ... is deliberate to keep the output
of the PANIC line as consistent as possible with the historical smbd output.

a26be7eeed s3:lib: avoid calling async_connect_send() again and again in open_socket_out*()
There's really no need to do that!

Once connect() is called and returned EINPROGRESS, the kernel
knowns what to do and reports any state change via
TEVENT_FD_READ or TEVENT_FD_WRITE.
The actual success or failure is available via
getsockopt(.., SOL_SOCKET, SO_ERROR, ...).

Before this commit we called connect() (via async_connect_send()) again
and again until we reached the final caller provided timeout,
even if the kernel already found out that the destination is
unreachable.
