e353d123fd zephyr: Make Zephyr int types deprecated by default
As the int types defined in include/zephyr/types.h are typdef's we
utilize a Kconfig option (LEGACY_ZEPHYR_INT_TYPES) to enable/disable
the support for them.  By default to LEGACY_ZEPHYR_INT_TYPES not
being enabled and add an explicit test to ensure the types continue to
function until removed in the future.

7dc3ecd63d stdint.h: Make {u}int64_t types consistent regardless of arch
On 64-bit arch's like AARCH64, x86_64, or riscv-64 the way {u}int64_t
will differ from how its defined on 32-bit arch's.  Do the same trick we
do for {u}int32_t for {u}int64_t so that the type is the same regardless
of what we are building for.

This keeps things like %lld working the same regardless of 32-bit or
64-bit arch.

c951d71eba net: check permissions on net contexts
The original sockets system calls used file descriptors which
were actually net_context pointers. For all socket system calls,
any calls from user mode would check if the caller had permission
to use the net context.

This was later changed to not stuff net_context pointers into file
descriptors, but all the permission checking was unintentionally
lost, allowing all threads on the system to
read/write all socket file descriptors in the system at will, with
no way to isolate applications running on the same microcontroller
from each other's network activity.

This patch restores the permission checks on network context objects
for socket system calls that originated from user mode.

The call to z_object_recycle() was never removed from
zsock_socket_internal(); this is again leveraged to grant the
caller who opened the socket permission on the net_context
associated with the returned file descriptor.

To ensure that all socket calls do this checking, all uses of
z_get_fd_obj_and_vtable() have been routed through get_sock_vtable().

Objects have initialization state set and thread permissions
reset to just the caller in common zsock_socket() code.

be919d3bf7 userspace: improve dynamic object allocation
We now have a low-level function z_dynamic_object_create()
which is not a system call and is used for installing
kernel objects that are not supported by k_object_alloc().

Checking for valid object type enumeration values moved
completely to the implementation function.

A few debug messages and comments were improved.

Futexes and sys_mutexes are now properly excluded from
dynamic generation.

378024c510 userspace: add z_is_in_user_syscall()
Certain types of system call validation may need to be pushed
deeper in the implementation and not performed in the verification
function. If such checks are only pertinent when the caller was
from user mode, we need an API to detect this situation.

This is implemented by having thread->syscall_frame be non-NULL
only while a user system call is in progress. The template for the
system call marshalling functions is changed to clear this value
on exit.

A test is added to prove that this works.
