libc -- dmalloc: Call malloc_init as-needed, rather than via cc constructor.

dmalloc requires its own _nmalloc_thr_init be called before it can service
allocations. Applications with preinit arrays were able to call malloc before
constructors ran, which caused them to crash on uninitialized allocator state.

The change uses a flag to test for allocator init state. It is also careful
to not allow _nmalloc_thr_init to be called recursively from within pthread
initialization (slglobal.masked).

igb: Import Intel igb-2.2.3

Local changes
- Laundry the code
- Rewrite busdma related code
- Rewrite RX path
- Enable hardware TX IP chesksum

Integration w/ DragonFly's RSS and TX path optimization will be
conducted in the repository.

builtin.1: Bring in some enhancements from FreeBSD.

It is modeled after what they did but based on what we actually have in
our shells' source.

  as a script executing the builtin.

* Some further explanations and mdoc fixes.

tcp: Implement RFC4653 Non-Congestion Robustness (NCR)

It is enabled by default and can be disabled using sysctl node:
net.inet.tcp.ncr

As far as I have tested on heavily reordered network path, this
algorithm does avoid most of the spurious fast retransmits.  While
on the normal network path, the fast retransmits stil could be
triggered properly.

tcp: Improve RFC3517bis support

- Factor out tcp_fast_recovery()
- Delay fast retransmit or fast recovery for duplicated ACK which
  carries data or updates receiving window, so that
  o  The segments sent by fast retransmit/recovery could carry
     proper ack sequence and SACK information.
  o  Receiving window could get updated, so more new data could be
     injected into the network by the fast recovery.

examples/rconfig: Some fixes to our installation scripts.

* Allow the script to be run in a netbooted scenario, too.

* Raise the default size of the root partition to 768M (like the
  installer's default).

* While here, add some comments and whitespace.
