da413ebf3d Uuencode the sample "binary" firmware image file (instead of explicitly 
adding \0 bytes).  This is a technique that would be used in an actual
driver and is more suitable as an example.

3666785171 Avoid having a binary file in our source tree and instead create it at 
build time, to avoid possible grief maintaining FreeBSD source in

202bd73aea Small cleanup while being here: 
- sort includes
- remove usage(), since it seems to come from older version
  of the KLD
- remove unnecessary variable
- mark argc/argv as unused

719dd1ebed firmware(9) is a subsystem to load binary data into the kernel via a 
specially crafted module.  There are several handrolled sollutions to this
problem in the tree already which will be replaced with this.  They include
iwi(4), ipw(4), ispfw(4) and digi(4).

c7bf2569fa These patches implement dynamic sysctls. It's possible now to add 
and remove sysctl oids at will during runtime - they don't rely on
linker sets. Also, the node oids can be referenced by more than
one kernel user, which means that it's possible to create partially
overlapping trees.

Add sysctl contexts to help programmers manage multiple dynamic
oids in convenient way.

Please see the manpages for detailed discussion, and example module
for typical use.

This work is based on ideas and code snippets coming from many
people, among them:  Arun Sharma, Jonathan Lemon, Doug Rabson,
Brian Feldman, Kelly Yancey, Poul-Henning Kamp and others. I'd like
to specially thank Brian Feldman for detailed review and style
fixes.
