2f189e39a5 lib: os: Rename icmsg_buf to spsc_pbuf
Move icmsg_buf to lib/os and rename to spsc_pbuf (Single Producer
Single Consumer Packet Buffer). It is a generic module and initially
was created as internal module for ipc service.

aff6e8b2f7 lib: os: cbprint: enable tagged arguments for packaging
This adds some bits to support tagged arguments to be used for
packaging. If enabled, the packaging function no longer looks at
the format strings to determine the types of arguments, but
instead, each argument is tagged with a type by preceding it
with another argument as type (integer). This allows the format
strings to be removed from the final binary to conserve space.

eb710039c0 libc: minimal: Fix gmtime() userspace support
The gmtime() function returns a global result variable, and this
variable must be placed in the `z_libc_partition` when userspace is
enabled.

Since gmtime() makes use of a global variable and this results in a
footprint increase, this commit makes the time functions optional by
introducing `CONFIG_MINIMAL_LIBC_TIME` Kconfig and making them only
available when this option is enabled.

4735e10630 libc: minimal: Introduce CONFIG_MINIMAL_LIBC_NON_REENTRANT_FUNCTIONS
This commit introduces a new configuration called
`CONFIG_MINIMAL_LIBC_NON_REENTRANT_FUNCTIONS`, which enables the
traditional non-reentrant (i.e. not thread-safe) version of the C
standard library functions such as rand() and gmtime() when the
respective configs are enabled.

The non-reentrant functions make use of the globals and require an
additional memory partition (MPU region), which is scarce on low-end
devices, when CONFIG_USERSPACE=y.

The purpose of this option is to classify the MPU resource intensive
functions as a separate category and only enable them when there is a
demand for such.

d755050a14 libc: minimal: Add PRIxMAX macros for [u]intmax_t
This commit adds the missing `PRIxMAX` macros for the C99 `intmax_t`
and `uintmax_t` types:

  PRIdMAX, PRIiMAX, PRIoMAX, PRIuMAX, PRIxMAX, PRIXMAX

Note that the `PRIxMAX` macros specify the `ll` size modifier because
the type of the `intmax_t` for the minimal libc is defined as that of
the `int64_t`, which is always overridden to `long long int` by
`zephyr_stdint.h`; for more details, refer to the GitHub PR #29876,
which deliberately introduced this scheme.

In the future, this scheme will need to be reworked such that the
minimal libc `stdint.h` defines `intmax_t` as `__INTMAX_TYPE__`, and
the `inttypes.h` resolves the corresponding format specifier.

  PRIXFAST8, PRIXFAST16, PRIXFAST32, PRIXFAST64
  PRIXLEAST8, PRIXLEAST16, PRIXLEAST32, PRIXLEAST64

Note that these macros will eventually need to be defined according to
the toolchain-specified types when the `zephyr_stdint.h` hack is
removed in the future; refer to the the GitHub issue #46032 for more
details.
