LU-4420 fld: retry fld rpc even for ESHUTDOWN

when LWP is being evicted, because it is not replayable,
the request might return ESHUTDOWN or EWOULDBLOCK, instead
of failed, which might cause application failure, fld
client will retry RPC, until the connection is being setup
again or the LWP is being closed.

LU-4877 mdt: tolerate zero md_packed in mdt_fix_reply

The assertion for md_packed value is not really needed there,
if it is zero then buffer is not packed in reply and is not
needed, it is enough just unmark big buffer usage.

LU-4987 lustre: Remove static declaration in anonymous union

It is not permitted in C++ to have a static declaration inside
of an anonymous union.  Before "LUSTRE_ANONYMOUS_UNION_NAME"
was added to the code in commit b40f6327bb19b6, the g++ compiler
most likely complained with an error like this:

  error: ‘struct ost_id::<anonymous union>::ostid’ invalid; an
  anonymous union can only have non-static data members [-fpermissive]

The fix from b40f6327bb19b6 conditionally eliminated the anonymous
union when a C++ compiler is being used.  That means that the API
varies depending on your choice of compiler, which is not at all
desirable.

The better fix is to address the static data member that the error
complained about.  This patch changes the code to use an unnamed
struct in place of "struct ostid" inside of the anonymous union.
That name declaration was completely unnecessary anyway, since it
was not used anywhere else.

LU-4953 lprocfs: fix missing target_obds on multiple mounts

In the case of multiple mountes the target_obds only showed
up for the first mount. The reason for this was that we were
using procsym in obd_type to hold the pointer to the
proc_dir_entry for target_obds. But obd_type is shared across
all lmv/lov object instances. Instead we need to cache the
proc_dir_entry in the private data structure; lov_obd and
lmv_obd; for each type of obd device impacted. Later these
handles will be used for cleanup when the module unloads.

LU-5014 osd-ldiskfs: vfs_unlink api changed

In newer kernels the vfs_unlink api changed to take
more arguments.  This patch creates a wrapper to let us adapt
to the different versions of vfs_unlink in old and new kernels.
As vfs_unlink is only used in server code
this only impacts server builds of lustre.
