selftest: add some basic testing for the io_uring vfs module
We're now able to build it on all linux systems and
the ci runners have at least a 5.4 kernel. That's
all the current vfs_io_uring requires.

libnetapi: Use lpcfg_set_cmdline()
Replace lp_set_cmdline() with lpcfg_set_cmdline() in netapi.c.
For this purpose:
1. Add loadparm_context to the libnetapi_ctx because we need it
in libnetapi_set_debuglevel() and libnetapi_set_logfile().
2. Move loadparm_context creation from libnetapi_net_init()
to libnetapi_init() and add the lp_ctx parameter to the former.

build: Remove -Wno-error=missing-field-initializers from Heimdal build
This allows this warning (error) to be used in Samba for cases where a

the GCC versions we build on do not regard foo = {} as an error.

s4:kdc: Make ‘struct pac_blobs’ memory handling safer and more consistent
Having pac_blobs::type_blobs be managed both by talloc and by the
‘pac_blobs’ structure itself (with pac_blobs_destroy()) is very prone to
error. So is the current situation of having the other ‘pac_blobs’
functions each take in a memory context.
Improve these circumstances by requiring ‘pac_blobs’ to be managed by
talloc. Now the other functions can dispense with their ‘mem_ctx’
parameters, being instead able to allocate on to the ‘pac_blobs’
structure itself. pac_blobs_init() no longer must be a separate
function; inline it into pac_blobs_from_krb5_pac(). pac_blobs_destroy(),
being no longer of use, can go too.

s4:kdc: Add correct Asserted Identity SID in response to an S4U2Self request
I’m not sure exactly how this check was supposed to work. But in any
case, within fast_unwrap_request() the Heimdal KDC replaces the outer
padata with the padata from the inner FAST request. Hence, this check
does not accomplish anything useful: at no point should the KDC plugin
see the outer padata.
A couple of unwanted consequences resulted from this check. One was that
a client who sent empty FX‐FAST padata within the inner FAST request
would receive the *Authentication Authority* Asserted Identity SID
instead of the *Service* Asserted Identity SID. Another consequence was
that a client could in the same manner bypass the restriction on
performing S4U2Self with an RODC‐issued TGT.
Overall, samba_wdc_is_s4u2self_req() is somewhat of a hack. But the
Heimdal plugin API gives us nothing better to work with.

nsswitch/wb_common.c: fix socket fd and memory leaks of global state
When we are called in wb_atfork_child() or winbind_destructor(),
wb_thread_ctx_destructor() is not called for the global state
of the current nor any other thread, which means we would
leak the related memory and socket fds.
Now we maintain a global list protected by a global mutex.
We traverse the list and close all socket fds, which are no
longer used (winbind_destructor) or no longer valid in the
current process (wb_atfork_child), in addition we 'autofree'
the ones, which are only visible internally as global (per thread)
context.

nsswitch/wb_common.c: don't operate on a stale wb_global_ctx.key
If nss_winbind is loaded into a process that uses fork multiple times
without any further calls into nss_winbind, wb_atfork_child handler
was using a wb_global_ctx.key that was no longer registered in the
pthread library, so we operated on a slot that was potentially
reused by other libraries or the main application. Which is likely
to cause memory corruption.
So we better don't call pthread_key_delete() in wb_atfork_child().
