When available, use the GCC / Clang builtins to implement the
math_extras functions. Otherwise, use the portable versions.
Signed-off-by: Jakob Olesen <jolesen@fb.com>
Compilers based on Clang provide a __has_builtin(x) macro which can be
used to detect in the preprocessor if a given builtin function is
supported by the compiler.
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.

can_attach_workq is an isr wrapper that puts a work item into a workq

sntp_simple() function queries the server (passed as "addr[:port]"

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.

Not in POSIX. Linux man getnameinfo says about it:
"In order to assist the programmer in choosing reasonable sizes for
the supplied buffers, <netdb.h> defines the constants
#define NI_MAXHOST 1025
#define NI_MAXSERV 32
Since glibc 2.8, these definitions are exposed only if suitable
feature test macros are defined, namely: _GNU_SOURCE, _DEFAULT_SOURCE
(since glibc 2.19), or (in glibc versions up to and including 2.19)
_BSD_SOURCE or _SVID_SOURCE."

Unfortunately, Zephyr SDK 0.10.0 ships with outdate Newlib 2.0.0

ugly workaround of defining struct timeval inline (the whole idea
was to standardize on sys/_timeval.h header for different libc's).
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
According to POSIX, that's the header which defines this function.
Similarly, nothing in POSIX indicates that <time.h> should have
access to struct timeval, so it's removed (it's made accessible
to <sys/time.h> via <sys/_timeval.h> introduced earlier).

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.

It will help to use IS_ENABLED in place of #ifdef in relevant place.
Only struct net_if uses this structure.
In case only IPv4 is used, it will bloat up this struct by 12 bytes.
There are few reasons why this is "ok" in this case:
- On limited rom/ram system it will be unlikely to find a lot of
network interfaces so it should not harm much to raise the size of
struct net_addr.
- If IPv4 is the only enabled IP version, it gains a good amount of
rom/ram to discard IPv6 support so it is fine to steal a bit of this
gain to bloat up a bit struct net_addr.
