Introduce the notion of static linker scripts to allow libncursesw.a to
track its dependency on libtinfow.a
this allows the build of older freebsd source tree to happen and make
static linking in part with dynamic linking which already provides a
ldscript
This fixes a bootstrapping FreeBSD 12 or 13 on recent FreeBSD 14

Define structures related to the depop set of commands (GET PHYSICAL ELEMENT
STATUS, REMOVE ELEMENT AND TRUNCATE, and RESTORE ELEMENT AND REBUILD) as
well as the CDB construction routines.
Also create scsi_wrap.c. This will have convenience routines that will do all
the elements of allocating the ccb, generating the CDB, sending the command
(looping as necessary for cases where data is returned, but it's size isn't
known up front), etc. As this functionality is fleshed out, calling many

Each locale embeds a lazily initialized lconv which is populated by
localeconv(3) and localeconv_l(3). When setlocale(3) updates the global
locale, the lconv needs to be (lazily) reinitialized. To signal this,
we set flag variables in the locale structure. There are two problems:
- The flags are set before the locale is fully updated, so a concurrent
localeconv() call can observe partially initialized locale data.
- No barriers ensure that localeconv() observes a fully initialized
locale if a flag is set.
So, move the flag update appropriately, and use acq/rel barriers to
provide some synchronization. Note that this is inadequate in the face
of multiple concurrent calls to setlocale(3), but this is not expected
to work regardless.
Thanks to Henry Hu <henry.hu.sh@gmail.com> for providing a test case
demonstrating the race.

On case-insensitive file systems (most likely to be seen on macOS, where
it is the default), _Fork.o for the new POSIX _Fork function conflicts
with _fork.o for the PSEUDO file. This results in non-determinsitic
behaviour in terms of which ends up being present; if _Fork.o wins then
the build fails to link libc.so due to missing __sys_fork, and if
_fork.o wins then libc silently fails to include the implementation of
_Fork. A similar issue occurred in the past for C99's _Exit conflicting
with exit(2) and was fixed in cb1cb6a2a83f, so this adds a fix based on
that.
As a longer-term solution it might be better to instead make the
generated files use a different prefix that's less likely to conflict
with other things (such as __sys_foo.o given they always contain that)
but that's a rather more invasive change.

Some notable changes, from upstream's release notes:
- sshd(8): Remove support for obsolete "host/port" syntax.
- ssh(1): When prompting whether to record a new host key, accept the key
fingerprint as a synonym for "yes".
- ssh-keygen(1): when acting as a CA and signing certificates with an RSA
key, default to using the rsa-sha2-512 signature algorithm.
- ssh(1), sshd(8), ssh-keygen(1): this release removes the "ssh-rsa"
(RSA/SHA1) algorithm from those accepted for certificate signatures.
- ssh-sk-helper(8): this is a new binary. It is used by the FIDO/U2F
support to provide address-space isolation for token middleware
libraries (including the internal one).
- ssh(1): this release enables UpdateHostkeys by default subject to some
conservative preconditions.
- scp(1): this release changes the behaviour of remote to remote copies
(e.g. "scp host-a:/path host-b:") to transfer through the local host
by default.
- scp(1): experimental support for transfers using the SFTP protocol as
a replacement for the venerable SCP/RCP protocol that it has
traditionally used.
Additional integration work is needed to support FIDO/U2F in the base
system.
