The vast majority of these changes are in Linux specific code.
They are the result of not having an automated style checker to
validate the code when it was originally written. Others were
caused when the common code was slightly adjusted for Linux.
This patch contains no functional changes. It only refreshes
the code to conform to style guide.
Everyone submitting patches for inclusion upstream should now
run 'make checkstyle' and resolve any warning prior to opening
a pull request. The automated builders have been updated to
fail a build if when 'make checkstyle' detects an issue.

Porting notes:
1. zfs_dbgmsg_print() is only used in userland. Since we do not have
mdb on Linux, it does not make sense to make it available in the
kernel. This means that a build failure will occur if any future
kernel patch depends on it. However, that is unlikely given that
this functionality was added to support zdb.
2. zfs_dbgmsg_print() is only invoked for -VVV or greater log levels.
This preserves the existing behavior of minimal noise when running
with -V, and -VV.
3. In vdev_config_generate() the call to nvlist_alloc() was not
changed to fnvlist_alloc() because we must pass KM_PUSHPAGE in
the txg_sync context.

Closes#1509
When configuring the spl debug log support use the provided wrapper
functions. This ensures that if --disable-debug-log was used when
buiding the spl the functions will have no effect.

Historically the internal zfs debug infrastructure has been
scattered throughout the code. Since we expect to start making
more use of this code this patch performs some cleanup.
* Consolidate the zfs debug infrastructure in the zfs_debug.[ch]
files. This includes moving the zfs_flags and zfs_recover
variables, plus moving the zfs_panic_recover() function.
* Remove the existing unused functionality in zfs_debug.c and
replace it with code which correctly utilized the spl logging
infrastructure.
* Remove the __dprintf() function from zfs_ioctl.c. This is
dead code, the dprintf() functionality in the kernel relies
on the spl log support.
* Remove dprintf() from hdr_recl(). This wasn't particularly
useful and was missing the required format specifier anyway.
* Subsequent patches should unify the dprintf() and zfs_dbgmsg()
functions.
