67978f8ffc ring_buffer: delete redundant code
No need to clamp requested size as ring_buf_get_claim() does it already.

836514c9dd sys: timeutil: expose and use macro for base year
timeutil internally uses 1900 as base year for calculation,
that is hidden from caller context. Thus declared a macro in
the public header file, and uses that macro will let caller adjust the
calulations accordingly.

878640fa08 json: support parsing and serializing 'int64_t'
Up to now there was only support for parsing/encoding 32-bit integer
numbers, with no support for larger ones.

Introduce support for 'int64_t' type, so that large numbers can be
serialized into JSON payloads.

3afd9429c0 json: Fix alignment calculation for nested objects
Currently, json array macros are passing the outer "container" struct
to the Z_JSON_ELEMENT_DESCR macro, causing the alignment to be calculated
from the outer struct which may be incorrect. Fix this by using the
biggest shift from the nested objects to calculate the alignment as the
struct size is calculated based on the biggest alignment of it's members.

4cf00a6125 zephyr: Add zero-len check for utf8_trunc
The function did not check if the provided string had a zero
length before starting to truncate, which meant that last_byte_p
could possible have pointed to the value before the string.

a2e97405d0 lib: check null pointer before taking lock for bitarray
In some function in bitarray.c, we should check the pointer
of bitarry before taking bitarray lock.

In this patch, we move the null-check assert before the use of
the struct to provide better validation than a crash.
