r337871:
pkgfs_init: Initialize pkg

new_package may not set *pp if it errors out, leaving pkg uninitialized.

r339970:
Remove unnecessary include from libstand.

r342151:
loader: zfs reader should not probe partitionless disks

First of all, normal setups can not boot such pools as the tools
do not support installing boot programs.

Secondly, for proper pool configuration detection, we need to checks all
four label copies on disk, 2 from front and 2 from the end of the disk,
but zfs label does not contain the size of the disk - so we depend on
firmware to report the correct disk size or use information from the
partition table.

Without partition table, we only can rely on firmware to report and support
disk IO properly.

There is a specific case: 8TB disks are reported by BIOS to have 4294967295
sectors (0x00000000ffffffff), the sectors reported by OS is 15628053168
(0x00000003a3812ab0), so the reported size is less than actual but is hitting
32-bit max. Unfortuantely the real limit must be even lower because probing
this disk in this system will wnd up with hung system.

UEFI boot of this system seems not to be affected.

r342161:
loader: zfs reader should not probe partitionless disks (UEFI case)

With r342151 I did fix the BIOS version of zfs_probe_dev() from accessing
the whole disk, but the fix was not complete - we actually did not check
if the device name was really for whole disk. Since UEFI version
is only calling the zfs_probe_dev() with partitions and not with whole
disk, the UEFI loader was not able to find the zfs pools.

This update does correct the issue by calling archsw.arch_getdev() to
translate the device name back to dev_desc, and we have whole disk when both
partition and slice values are -1.

r343123:
loader should ignore active multi_vdev_crash_dump feature on zpool

Since the loader zfs reader does not need to read the dump zvol, we can
just enable the feature.

r343124:
libsa: add asprintf()

asprintf() is a nice tool for string processing.

r344226:
Fix memory corruption bug introduced in r325310

The bug occurred when a bounce buffer was used and the requested read
size was greater than the size of the bounce buffer.  This commit also
rewrites the read logic so that it is easier to systematically verify
all alignment and size cases.

r344234:
It turns out r344226 narrowed the overrun bug but did not eliminate it entirely

This commit fixes a remaining output buffer overrun in the
single-sector case when there is a non-zero tail.

r344248:
cd9660: dirmatch fails to unmatch when name is prefix for directory record

Loader does fail to properly match the file name in directory record and
does open file based on prefix match.

For fix, we check the name lengths first.

r344387:
loader: really fix cd9660 dirmatch

The cd9660_open() does pass whole path to dirmatch() and we need to
compare only the current path component, not full path.

Additinally, skip over duplicate / (if any) and check if the last component
in the path was meant to be directory (having trailing /). If it is in fact
a file, error out.
