staging: lustre: make signal-blocking functions inline

cfs_block_sigsinv() and cfs_restore_sigs() are now
simple enough to inline them.
This means we can discard linux-prim.c

staging: lustre: improve API and implementation of blocking signals.

According to comment for set_current_blocked() in
kernel/signal.c, changing ->blocked directly is wrong.
sigprocmask() should be called instead.

So change cfs_block_sigsinv() and cfs_restore_sigs()
to use sigprocmask().
For consistency, change them to pass the sigset_t by reference
rather than by value.

Also fix cfs_block_sigsinv() so that it correctly blocks
signals above 32 on a 32bit host.

staging: lustre: lnet: remove cfs_block_allsigs calls.

Both places that cfs_block_allsigs() is used here,
the goal is to turn an interruptible wait into an
uninterruptible way.
So instead of blocking the signals, change TASK_INTERRUPTIBLE to
TASK_NOLOAD.
In each case, no other functions called while signals are blocked
will sleep - just the one that has been fixed.
In one case, an extra 'interruptible' flag needs to be passed
down so the waiting decision can be made at the right place.

staging: lustre: remove unnecessary cfs_block_allsigs() calls

Threads started by kthread_run() ignore all signals,
as kthreadd() calls ignore_signals(), and this is
inherited by all children.
So there is no need to call cfs_block_allsigs() in functions
that are only run from kthread_run().

cfs_cap_raised() is trivial - one line.
cfs_cap_raise() and cfs_cap_lower() are used as a pair
which is more effectively implemented with
override_cred() / revert_creds().

staging: lustre: replace all CFS_CAP_* macros with CAP_*

Lustre defines a few CFS_CAP_* macros which are exactly the
same as the corresponding CAP_* macro, with one exception.

CFS_CAP_SYS_BOOT is 23
CAP_SYS_BOOT is 22.

CFS_CAP_SYS_BOOT is only used through CFS_CAP_FS_MASK and
causes capability 23 (CAP_SYS_NICE) to be dropped in certain
circumstances.
It is probable that the intention was to drop CAP_SYS_BOOT,
and this is what is now done.

CFS_CAP_CHOWN_MASK and CFS_CAP_SYS_RESOURCE_MASK are never
used, so they have been removed.
