If the system sets its clock frequency at runtime, this is
stored in a variable that can't be directly read by user
mode. For this case only, add a system call to fetch its
value and modify the definition of
sys_clock_hw_cycles_per_sec() to use it.
Since this is now a system call, store in a temporary variable
inside z_ms_to_ticks(). The syscall overhead only applies
when called from user mode, other contexts are completely
inlined.
Added stub syscall header for mocking framework, to get rid
of inclusion errors.

on non-XIP system, SRAM is the default region, and relocated .data
section and .bss section of SRAM shouldn't be inserted between
_image_rom_start and _image_rom_end, because the memory region between
_image_rom_start and _image_rom_end will construct the mpu ro region.
Also for the newly added memory region on non-XIP system, the

A vendor defined callback can be registered to be called when
vendor-Specific events are received in the stack. The callback can then
decode and handle the event; if not the stack will decode and handle
the event.

From POSIX.1-2017:
The getsockname() function shall retrieve the locally-bound name of the
specified socket, store this address in the sockaddr structure pointed
to by the address argument, and store the length of this address in the
object pointed to by the address_len argument.
The address_len argument points to a socklen_t object which on input
specifies the length of the supplied sockaddr structure, and on output
specifies the length of the stored address. If the actual length of the
address is greater than the length of the supplied sockaddr structure,
the stored address shall be truncated.
If the socket has not been bound to a local name, the value stored in
the object pointed to by address is unspecified.

Compilers based on Clang provide a __has_builtin(x) macro which can be

For other compilers (notably GCC), we provide an alternative definition
of HAS_BUILTIN(x) that depends on the toolchain-specific header file to
declare which builtin functions are supported based on the current
compiler version.

Add a <misc/math_extras.h> header file with portable implementations of
a number of commonly used math and bit counting operations that are not
available in the C programming language.
The math_extras functions fall into two groups:
1. Unsigned integer arithmetic with overflow detection. Addition and
multiplication are provides for the u32_t, u64_t, and size_t types.
This commit doesn't include subtraction and division, and there are
no signed operations. These could be added later if there is a need.
2. Bit-counting operations like clz, ctz, and ffs. These are provided
for u32_t and u64_t only. I don't see a need for size_t operations,
but they could be added if needed.
A follow-on commit will add more efficient implementations using
compiler builtins for those compilers that support it.
Another commit will replace other uses of "naked" compiler builtins with
calls to these functions.

Two utils to manipulate addresses in format "addr[:port]". I.e.,
network address (domain name or numeric), optionally followed by
port number:
* net_addr_str_find_port(), to return pointer to port number
substring (or NULL if not present).
* net_getaddrinfo_addr_str(), which is effectively getaddrinfo()
wrapper taking a "addr[:port]" string as a parameter.
The header file is named socketutils.h to emphasize that these
utility functions are implemented on top of BSD Sockets API
(and other POSIX/ANSI C functions), and thus portable to other
POSIX systems (e.g., Linux), so can be used in apps testing
POSIX compatibility. More utility functions (beyond address
manipulation) can be added later.

#define NI_MAXHOST 1025

Since glibc 2.8, these definitions are exposed only if suitable

_BSD_SOURCE or _SVID_SOURCE."

According to POSIX, that's the header which defines this function.
Similarly, nothing in POSIX indicates that <time.h> should have

Some applications using DMA, such as UART RX, could
need to complete the current DMA transaction earlier than
predefined, based on other termination conditions,
like UART's IDLE interrupts.
In that case, the client needs to know how many data are
still left in DMA transfer buffer so that it can figure
out how many data has been transfered. However, the current
DMA API doesn't provide any information for the client
to learn the transfer buffer information.
And some other information, like whether DMA transfer is busy
or not, transfer direction, etc, could interest a client.
So, added a dma API function to retrieve the current DMA
runtime status.
And implemented the API for STM32F4's DMA while keeping
others unimplemented.
