Several of the zfs utilities allow you to pass a vdev's guid rather
than the device name. However, the utilities are not consistent in
how they parse that guid. For example, 'zinject' expects the guid
to be passed as a hex value while 'zpool replace' wants it as a
decimal. The user is forced to just know what format to use.
This patch improve things by making the parsing more tolerant.
When strtol(3) is called using 0 for the base, rather than say
10 or 16, it will then accept hex, decimal, or octal input based
on the prefix. From the man page.
If base is zero or 16, the string may then include a "0x"
prefix, and the number will be read in base 16; otherwise,
a zero base is taken as 10 (decimal) unless the next character
is '0', in which case it is taken as 8 (octal).
NOTE: There may be additional conversions not caught be this patch.

Issue #2
For the same reasons it's used in libzfs_init(), this was just
overlooked because zinject gets minimal use.

NOTES: This patch has been reworked from the original in the
following ways to accomidate Linux ZFS implementation
*) Usage of the cyclic interface was replaced by the delayed taskq
interface. This avoids the need to implement new compatibility
code and allows us to rely on the existing taskq implementation.
*) An extern for zfs_txg_synctime_ms was added to sys/dsl_pool.h
because declaring externs in source files as was done in the
original patch is just plain wrong.
*) Instead of panicing the system when the deadman triggers a
zevent describing the blocked vdev and the first pending I/O
is posted. If the panic behavior is desired Linux provides
other generic methods to panic the system when threads are
observed to hang.
*) For reference, to delay zios by 30 seconds for testing you can
use zinject as follows: 'zinject -d <vdev> -D30 <pool>'
