The POSIX_MAX_FDS option does not correspond to any standard
POSIX option. It was used to define the size of the file
descriptor table, which is by no means exclusively used by
POSIX (also net, fs, ...).
POSIX_MAX_FDS is being deprecated in order to ensure that
Zephyr's POSIX Kconfig variables correspond to those defined in
the specification, as of IEEE 1003.1-2017. Namely,
POSIX_OPEN_MAX. CONFIG_POSIX_MAX_OPEN_FILES is being deprecated
for the same reason.
To mitigate any possible layering violations, that option is
not user selectable. It tracks the newly added
CONFIG_ZVFS_OPEN_MAX option, which is native to Zephyr.
With this deprecation, we introduce the following Kconfig
options that map directly to standard POSIX Option Groups by
simply removing "CONFIG_":
* CONFIG_POSIX_DEVICE_IO
Similarly, with this deprecation, we introduce the following
Kconfig options that map directly to standard POSIX Options by
simply removing "CONFIG":
* CONFIG_POSIX_OPEN_MAX
In order to maintain parity with the current feature set, we
introduce the following Kconfig options.
* CONFIG_POSIX_DEVICE_IO_ALIAS_CLOSE
* CONFIG_POSIX_DEVICE_IO_ALIAS_OPEN
* CONFIG_POSIX_DEVICE_IO_ALIAS_READ
* CONFIG_POSIX_DEVICE_IO_ALIAS_WRITE
Gate open(), close(), read(), and write() via the
CONFIG_POSIX_DEVICE_IO Kconfig option and move
implementations into device_io.c, to be conformant with the
spec.
Lastly, stage function names for upcoming ZVFS work, to be
completed as part of the LTSv3 Roadmap (e.g. zvfs_open(), ..).

Instead of using net_context API directly, the DNS resolver is
changed to use the socket service API. This allows DNS access
for offloaded sockets and can lower overall memory consumption.

The setting is deprecated so change the code to either use the
native zsock_* API or enable POSIX_API to use the BSD socket API.

Previously, the test was only run for configurations that used
the Newlib C library. However, socketpair runs equally well
under the minimal libc, and picolibc, as well as the native
libc.

Fixes: #38403
Adding NET_DRIVERS menuconfig so that network drivers are grouped
together in its own menu entry under drivers, similar to most other
drivers.
This further has the advantages that `CONFIG_NET_DRIVERS` can be used
for testing to determine if network drivers has been selected.
This changed revealed a dependency loop where both `select` (for SLIP)
and `depends` (for PPP) which both depends on NET_DRIVERS` where in use
in the dependency tree for Qemu networking, especially NET_SLIP_TAP.
This is handled by defaulting `NET_DRIVERS` to `y` when building for a
Qemu target.
`SLIP` had a dependency to `!QEMU_TARGET || NET_QEMU_SLIP`. This is
changed so that SLIP prompt depends on `!QEMU_TARGET` which provides
full user control in hardware but makes the symbol promptless on Qemu
targets.

Kernel objects were being directly accessed without previously
calling k_thread_access_grant().
This change allows each test that requires an asynchronous
event to send it to a common work queue with correct
permissions.
