150c26cb34 Use rtalloc1() instead of rtalloc_ign(). It returns a locked 
rtentry. We quickly copy the fields of interest, and then
RTFREE_LOCKED(). This should be faster then lock & unlock the
rtentry twice.

397c19d175 Remove explicit locking of struct file. 
- Introduce a finit() which is used to initailize the fields of struct file
   in such a way that the ops vector is only valid after the data, type,
   and flags are valid.
 - Protect f_flag and f_count with atomic operations.
 - Remove the global list of all files and associated accounting.
 - Rewrite the unp garbage collection such that it no longer requires
   the global list of all files and instead uses a list of all unp sockets.
 - Mark sockets in the accept queue so we don't incorrectly gc them.

3de213cc00 Add a new 'why' argument to kdb_enter(), and a set of constants to use 
for that argument.  This will allow DDB to detect the broad category of
reason why the debugger has been entered, which it can use for the
purposes of deciding which DDB script to run.

Assign approximate why values to all current consumers of the
kdb_enter() interface.

b332b91f74 - Merge all the ng_send_fn2* functions into one - ng_send_fn2(), 
removing some copy&pasted code.
- Reduce copy and paste in ng_apply_item().
- Resurrect ng_send_fn() as a valid symbol, not a define.

e088dd4c44 Implement new apply callback mechanism to handle item forwarding. 
When item forwarded refence counter is incremented, when item
processed, counter decremented. When counter reaches zero,
apply handler is getting called.
Now it allows to report right connect() call status from user-level
at the right time.
