This change is equivalent to the approach committed in r306417, but if
sed has a bug it could be exploited by the untrusted tar file. Instead,
generate the expected tar content and compare that with find's output.
convert the expected hash list to the expected tar content filesystem

R_AARCH64_RELATIVE relocation found on arm64. It would try to add the
contents of the memory location being relocated to the base address and
the relocation addend. This worked when the contents was zero, however
this now seems to be set to the value of the addend so we add this twice.
Fix this by just setting the memory to the computed value.

that can be compiled on various OSes (including on older versions
of FreeBSD), make it possible to have it include the partitioning
scheme definitions without pulling in FreeBSD specifics.
In particular this means:
o move the scheme definitions iand related defines to header files
under sys/disk,
o make them (more) portable by using uint#_t (where applicable)
and renaming defines so that they at least have a good prefix,
o make the new headers stand-alone so that they don't need FreeBSD
definitions, like struct uuid(*)
o keep the original headers for compatibility, but rewrite them to
get the scheme definitions from <sys/disk/$scheme.h>.
(*) since UUID/GUID type definitions are non-portable and the GPT
scheme uses them, make it possible to have the scheme definitions
use an external type by allowing consumers of the header to set
GPT_UUID_TYPE. When GPT_UUID_TYPE has not been defined, the header
will use it's own type definition, which is the same as struct uuid.
The gpt_uuid_t typedef is created to abstract the details and allows
consumers to refer to a single type.
There is not conflict between the partitioning scheme headers and
what is defined in them. All headers can be included in the same
source files.
Note: consumers of the old headers have not been changed yet. Such
will be done if and when needed/beneficial.

shell, ensure that we do sleep for at least the specified time, in
presence of signals.
Interrupted sleep(3) is followed by _exit(), which might cause 'Going
nowhere without my init' panic if init(8) exits before the reboot(2)
really started, or before SIGTSTP stopped init(8) (both events are
initiated by the parallel reboot(8) operation).
I do not see other calls to sleep(STALL_TIMEOUT) as having the same
disasterous consequences and kept them as is until the similar change
is proven required.

This should allow vn_fullpath() to work even when vfs name cache is
disabled for zfs, which is the case when zfs properties like
casesensitivity and normalization are set non-default values.
The new code should be 100% reliable for directories and "mostly"
reliable for files, that is, when hardlinks across directories are
not used.

=====
I had originally suspected the parsing of ctype definition files as being
the source of the ctype flag mis-definitions, but it wasn't. In the
process, I simplified the cc_list parsing so I'm committing the no-impact
improvement separately. It removes some parsing redundancies and
won't parse partial range definitions anymore.

This commit is from John Marino in dragonfly with the following commit log:
====
This was a CTYPE encoding error involving consecutive points of the same
ctype. It was reported by myself to Illumos over a year ago but I was
unsure if it was only happening on BSD. Given the cause, the bug is also
present on Illumos.
Basically, if consecutive points were of the exact same ctype, they would
be defined as a range regardless. For example, all of these would be
considered equivalent:
<A> ... <C>, <H> (converts to <A> .. <H>)
<A>, <B>, <H> (converts to <A> .. <H>)
<A>, <J> ... <H> (converts to <A> .. <H>)
So all the points that shouldn't have been defined got "bridged" by the
extreme points.
The effects were recently reported to FreeBSD on PR 213013. There are
countless places were the ctype flags are misdefined, so this is a major
fix that has to be MFC'd.

A premature optimization lead to caching a native-sector sized memory
