Sync: merge r215189 through r215272 from ^/head.

In printfile(), exit the process instead of only printing the warning.
This fixes verbose mode when either -i specified non-existent kldfile
id, or the file was unloaded between two kldnext(2) calls.

While there, fix printfile() definition to be style(9)-compliant.

Casting size_t to uintmax_t is not necessary anymore. This also
removes the need for stdint.h inclusion.

Merge from head up to r188941 (last revision before the USB stack switch)

Only show the pathname in verbose output as intended in the last commit (r172862).

Add the full module path name to the kld_file_stat structure
for kldstat(2).

This allows libdtrace to determine the exact file from which
a kernel module was loaded without having to guess.

Add the full module path name to the kld_file_stat structure
for kldstat(2).

This allows libdtrace to determine the exact file from which
a kernel module was loaded without having to guess.

The kldstat(2) API is versioned with the size of the
kld_file_stat structure, so this change creates version 2.

Add the pathname to the verbose output of kldstat(8) too.

Update usage.

Add '-q' option, which (when used with '-m' option) just tells if the given
module is loaded or compiled into the kernel.

Add '-q' option, which (when used with '-m' option) just tells if the given
module is loaded or compiled into the kernel.
This is useful mostly in startup scripts, when module should be loaded only
if it wasn't compiled into the kernel nor already loaded, eg.:

kldstat -q -m g_eli || kldload geom_eli.ko || err 1 'geom_eli module failed to load.'

Synchronize program's usage() with manpage's SYNOPSIS.

Add -m option (find module using modfind() and stat it).

Use a better way to calculate POINTER_WIDTH suggested by pjd@.

Decide how much space we need to print a pointer using
sizeof(void *) rather than if __alpha__ is defined.

Validate argument to -i.

Use __FBSDID() to quiet GCC 3.3 warnings.

style(9): use NULL when assigning/comparing a char *,
consitently compare fileid with 0 using == and !=.

Backout rev 1.8. This really does not give us the version number
of the kld's.

Pointed out by: bp

the -v flag.

Properly align the columns of the header on Alpha.

$Id$ -> $FreeBSD$

Cosmetic fix (make header align with data)

Sync. usage string and synopsis. Add rcsid.

a few code style changes:
o start function names in column 1
o sort order of flags in getopt and switch
o don't try to reference progname
o unspam some changes introduced by a 2.2.1-R
