Fix usr.sbin/extattr testcases on tmpfs

Skip the usr.sbin/extattr testscases if $TMPDIR is tmpfs, which doesn't
support extended attributes

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.

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.

Fix return type of extattr_set_* and fix rmextattr(8) utility.

extattr_set_{fd,file,link} is logically a write(2)-like operation and
should return ssize_t, just like extattr_get_*. Also, the user-space
utility was using an int for the return value of extattr_get_* and
extattr_list_*, both of which return an ssize_t.

Don't print an empty line for files with no attributes when -q is given for
lsextattr(8).

extattr: Fix a signed/unsigned issue

Submitted by: Matthew Fleming <matthew.fleming@isilon.com>
Reviewed by: zml, dfr

Fix a bug when printing attributes from multiple files: buflen could be
longer than the length of the current attribute if the buffer were reused
and previously longer, so bits of the previous, longer attribute would be
written. Fix this by using the actual attribute length.

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

Invoke err() with a format string rather than directly with a passed
command line argument.

Update lsextattr(8) to use the new extattr_list_*() APIs, rather than
using the somewhat more hackish variant on extattr_get_*() to retrieve
the attribute list on an object.

Add -h flags to each of the *extattr(8) commands, indicating that
the command should not follow the symlink if the target file is a
symlink. Invoke the extattr_*_link(2) version of the system call
in that situation, instead of extattr_*_file(2). This is
consistent with other attribute management tools in the system.

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.
