b215ceaaec Add sem_clockwait_np()
This function allows the caller to specify the reference clock
and choose between absolute and relative mode.  In relative mode,
the remaining time can be returned.

The API is similar to clock_nanosleep(3).  Thanks to Ed Schouten
for that suggestion.

While I'm here, reduce the sleep time in the semaphore "child"
test to greatly reduce its runtime.  Also add a reasonable timeout.

Replace uses of the GCC __nonnull__ attribute with the clang nullability

7502cc401b libkvm: support access to vmm guest memory, allow writes to fwmem and vmm
This change consists of two parts:
- allow libkvm to recognize /dev/vmm/* character devices as devices that
  provide access to the physical memory of a system (similarly to /dev/fwmem*)
- allow libkvm to recognize that /dev/vmm/* and /dev/fwmem* devices provide
  access to the physical memory of live remote systems and, thus, the memory
  is writable

As a result, it should be possible to run commands like
$ kgdb -w /path/to/kernel /dev/fwmem0.0

168fce73b5 hyperv/vss: Add driver and tools for VSS
VSS stands for "Volume Shadow Copy Service".  Unlike virtual machine
snapshot, it only takes snapshot for the virtual disks, so both
filesystem and applications have to aware of it, and cooperate the
whole VSS process.

This driver exposes two device files to the userland:

    /dev/hv_fsvss_dev

    Normally userland programs should _not_ mess with this device file.
    It is currently used by the hv_vss_daemon(8), which freezes and
    thaws the filesystem.  NOTE: currently only UFS is supported, if
    the system mounts _any_ other filesystems, the hv_vss_daemon(8)
    will veto the VSS process.

    If hv_vss_daemon(8) was disabled, then this device file must be
    opened, and proper ioctls must be issued to keep the VSS working.

    /dev/hv_appvss_dev

    Userland application can opened this device file to receive the
    VSS freeze notification, hold the VSS for a while (mainly to flush
    application data to filesystem), release the VSS process, and
    receive the VSS thaw notification i.e. applications can run again.

    The VSS will still work, even if this device file is not opened.
    However, only filesystem consistency is promised, if this device
    file is not opened or is not operated properly.

hv_vss_daemon(8) is started by devd(8) by default.  It can be disabled
by editting /etc/devd/hyperv.conf.

34168b28e9 Replace basename(3) by a thread-safe implementation.
Now that the changes to the dirname(3) function had some time to settle,
let's go ahead and use the same approach for replacing basename(3) by a
simple implementation that modifies the input string, thereby making it
thread-safe and guaranteed to succeed.

Unlike dirname(3), this function already had a thread-safe variant
basename_r(3). This function had its own set of problems, like having an
upper bound on the pathname length. Keep this function around for
compatibility, but remove most references from the man page. Make the
man page more similar to that of dirname(3).

As the basename_r(3) function is only provided by FreeBSD (and Bionic),
depending on its use is even more implementation defined than assuming
that basename(3) is thread-safe.

4ef9bd22ed Improve typing of POSIX search tree functions.
Back in 2015 when I reimplemented these functions to use an AVL tree, I
was annoyed by the weakness of the typing of these functions. Both tree
nodes and keys are represented by 'void *', meaning that things like the
documentation for these functions are an absolute train wreck.

To make things worse, users of these functions need to cast the return
value of tfind()/tsearch() from 'void *' to 'type_of_key **' in order to
access the key. Technically speaking such casts violate aliasing rules.
I've observed actual breakages as a result of this by enabling features
like LTO.

I've filed a bug report at the Austin Group. Looking at the way the bug
got resolved, they made a pretty good step in the right direction. A new
type 'posix_tnode' has been added to correspond to tree nodes. It is
still defined as 'void' for source-level compatibility, but in the very
far future it could be replaced by a proper structure type containing a
key pointer.

0974f66d06 In order to allow mkimg(1) (and other tools) to become a build tool
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.

directly.

2f5007f6d2 LC_*_MASK bit shifting order was partially broken from the initial commit

The order here should match XLC_* from "xlocale_private.h" which, in turn,
match LC_* publicly visible order from <locale.h> which determines how
locale components are stored in the structure.
LC_*_MASK -> XLC_* translation done as "ffs(mask) - 1" in the querylocale()
and equivalent shift loop in the newlocale(), so mapped to some wrong
components (excluding two mentioned above).

Formally the fix is ABI breakage, but old code using those masks

5f521d7ba7 Make libcrypt thread-safe. Add crypt_r(3).
glibc has a pretty nice function called crypt_r(3), which is nothing
more than crypt(3), but thread-safe. It accomplishes this by introducing
a 'struct crypt_data' structure that contains a buffer that is large
enough to hold the resulting string.

Let's go ahead and also add this function. It would be a shame if a
useful function like this wouldn't be usable in multithreaded apps.
Refactor crypt.c and all of the backends to no longer declare static
arrays, but write their output in a provided buffer.

There is no need to do any buffer length computation here, as we'll just
need to ensure that 'struct crypt_data' is large enough, which it is.
_PASSWORD_LEN is defined to 128 bytes, but in this case I'm picking 256,
as this is going to be part of the actual ABI.

variant.

938809f941 Fix up prototypes of basename(3) and dirname(3) to comply to POSIX.
POSIX allows these functions to be implemented in a way that the
resulting string is stored in the input buffer. Though some may find
this annoying, this has the advantage that it makes it possible to
implement this function in a thread-safe way. It also means that they
can be implemented in a way that they work for paths of arbitrary
length, as the output string of these functions is never longer than
max(1, len(input)).

Portable code already needs to be written with this in mind, so in my
opinion it makes very little sense to allow the existing behaviour.
Prevent the base system from falling back to this by switching over to
POSIX prototypes.

I'm not going to bump the __FreeBSD_version for this. The reason is that
it's possible to account for this change in a portable way, without
depending on a specific version of FreeBSD. An exp-run was done some
time ago. As far as I know, all regressions as a result of this have
already been fixed.

I'll give this change some time to settle. In the long run I want to

b240f5e262 Make strfmon_l() work without requiring the use of <xlocale.h>.
The strfmon_l() function provided by <xlocale/_monetary.h> is also part
of POSIX 2008's <monetary.h>, so it should be exposed by default.

Change the check used in <monetary.h> to be similar to the one that's
part of <wchar.h>, where we both test for __POSIX_VISIBLE and
_XLOCALE_H_.

2fed5061db Let dbm's datum::dptr use the right type.
According to POSIX, it should use void *, not char *. Unfortunately, the
dsize field also has the wrong type. It should be size_t. I'm not going
to change that, as that will break the ABI.

7e3327be32 Add missing va_list to <wchar.h>.
It looks like va_list should always be defined when XSI is enabled. It
moved over to the POSIX base in the 2008 edition.

0977bd1e88 Fix the signature of the psignal() function.
POSIX 2008 added the psignal() function which has already been part of
the BSDs for a long time. The only difference is, the POSIX version uses
an 'int' for the signal number, unlike our version which uses an
'unsigned int'. Fix up the function to use an 'int'. This should not
affect the ABI.

07acf54b4b Add missing types and constants to <netdb.h>.
According to POSIX, the netdb.h header must also provide in_addr_t and
in_port_t. It should also provide IPPORT_RESERVED. Copy over the
necessary bits from <netinet/in.h> to achieve that.
