Simplify the somewhat overcomplicated application interface; improves
readability and saves a bunch of lines.
Use designated struct initializers for clarity.

* Replaced all the spin lock/unlock wrappers from oz_polling_lock_bh()
and oz_polllin_unlock_bh() with spin_lock_bh(&g_polling_lock) and
spin_unlock_bh(&g_polling_lock).Completely erased the wrappers defination
and declaration.
* declared g_polling_lock as global variable in header file and added comments to it.
Module builded successfully with sparse without warnings.

Currently we call oz_pd_destroy() from softirq context, where we
try to destroy relevant data structures, as well we kill a tasklet
which always result in following kernel warning.
[12279.262194] Attempt to kill tasklet from interrupt
[12279.262202] Attempt to kill tasklet from interrupt
This patch defers deallocation of data structures to work queue.

This patch fix following issues reported by Dan:-
1) There is no check limiting the size to 32 and it could be up to
253 bytes.
2) Use defines instead of magic numbers.
3) The oz_farewell struct is supposed to be a variable length struct
but the variable part is put in the middle. It doesn't make any
sense to put the length of the variable size array after then end
of the array because we can never find it again! Put the
variable size array at the end. Make it a zero length array.
u8 len;
u8 report[0];
4) In oz_add_farewell() we do this:
f = kmalloc(sizeof(struct oz_farewell) + len - 1, GFP_ATOMIC);
The "- 1" refers to sizeof(f->report) but because it was a magic
number then it was missed when the sizeof(f->report) changed.
5) In [patch 6/6] we set the ->len member. But because it is at the
end of a variable length array with no limit check the remote
attacker can just rewrite it using the memcpy() on the next line.

Farewell report size can be bigger than one byte, increase array
size to accomodate maximum 32 bytes of farewell report.

Current implementation assumes HZ = 1000 for calculating
all internal timer intervals, which creates problem on
platforms where HZ != 1000.
As well we need resolution of less than 10 mSec for heartbeat
calculation, this creates problem on some platforms where HZ is
configured as HZ = 100, or around, which restricts us to timer interval
of 10 mSec. This is particularly found on embedded devices.
This patch moves on to use high resolution timers to calculate
all timer intervals as it allows us to have very small resolution
of timer interval, removing dependency on HZ.
