devd: Move variable declaration to header

Reminder by:	imp

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

According to devctl(4), clients must read events whole; they may not

2013-04-26T19:49:37+00:00

piece them together from multiple reads().  It's as if /dev/devctl is
a datagram device instead of a stream device.  However, devd's
internal buffer was too small (1025 bytes) to read an entire
ereport.fs.zfs.checksum event (variable, up to ~1300 bytes).  This
commit enlarges the buffer to 8k.

Add the ability to match the on a media type of the device in question.

Parse the ! lines that will soon be coming from the kernel. These are

events.

Create a new C++ header file called devd.hh which has all the class

2003-04-26T20:59:04+00:00

definitions in it.  Begin to document the classes that we use, and how
they interrelate (using comments that I can use with doxygen to
automatically generate docs with).

MFp4 (imp_freebsd branch): snapshot of devd work:

2002-12-07T08:04:36+00:00

o improve parsing and lexing
o create data structures based on the parsed file now.
o Still need to rewrite main loop and add regex (still uses hard coded
  devd-generic)
o minor man page updates.

# There should be one more commit before rc2

devd. A daemon that hooks into the kernel's /dev/devctl to produce

2002-10-20T22:15:17+00:00

arbitrary commands when devices come and go in the device tree (which is
different than the /dev directory).

This is an initial version.  Much of the planned power isn't here.
Instead of doing the full matching, we always run /etc/devd-generic.
/etc/devd.generic will go away at some point, I think.

I'm committing it in this early state so I can start getting feedback
from early adapters.
