Fix "getextattr -x" with non-ascii attribute values

extattr/rmextattr.c
When printing hex output, treat all attribute values as unsigned
char arrays instead of sign extending them to 32 bit values.

extattr/tests/extattr_test.sh
Add a regression test

Allow setextattr(8) to take attribute values from stdin

Add the -i option to setextattr. This option allow extended attribute data
to be provided via stdin. Add a -qq option to getextattr, which omits the
trailing newline. Together these options can be used to work with extended
attributes whose values are large and/or binary.

usr.sbin/extattr/Makefile:
Link against libsbuf which is used for processing stdin data.

usr.sbin/extattr/rmextattr.8:
Document setextattr's -i option, getextattr's -qq option, and remove
the BUG about setextattr only being useful for strings.

usr.sbin/extattr/rmextattr.c:
For setextattr operations, buffer attribute data in an sbuf. If -i
is specified, pull the data from stdin, otherwise from the
appropriate argurment.

Update usage text and argument validation code for setextattr's -i
option.

usr.sbin/extattr/tests/extattr_test.sh
Add tests for -q and -i.

Add PACKAGE fields to usr.sbin/extattr/tests/Makefile

usr.sbin/extattr/tests/Makefile
Add boiler plate required by 298107 but omitted by 298483. These
two changes passed through CR in parallel. I think this should get
the full test suite running in Jenkins again.

The last big commit: let usr.sbin/ use WARNS=6 by default.

Add the new userland tool for manipulating extended attributes.

This will replace the existing getextattr(8) and setextattr(8) with
a single binary responding to the names getextattr, setextattr,
rmextattr and lsextattr.

This program is not yet connected to the build.
