The network application API is a higher level API for creating
client and server type applications. Instead of applications
dealing with low level details, the network application API
provides services that most of the applications can use directly.
This commit removes the internal net_sample_*() API and converts
the existing users of it to use the new net_app API.

With CONFIG_NET_SOCKETS_POSIX_NAMES=y, "raw" POSIX names like
socket(), recv(), close() will be exposed (using macro defines).
The close() is the biggest culprit here, because in POSIX it
applies to any file descriptor, but in this implementation -
only to sockets.

Two changes are required so far:
* There's unavoidable need to have a per-socket queue of packets
(for data sockets) or pending connections (for listening sockets).
These queues share the same space (as a C union).
* There's a need to track "EOF" status of connection, synchronized
with a queue of pending packets (i.e. EOF status should be processed
only when all pending packets are processed). A natural place to
store it per-packet then, and we had a "sent" bit which was used
only for outgoing packets, recast it as "eof" for incoming socket
packets.

From
http://pubs.opengroup.org/onlinepubs/7908799/xns/netinetin.h.html:
in_addr_t
An unsigned integral type of exactly 32 bits.
[] the in_addr structure [] includes at least the following member:
in_addr_t s_addr
In other words, POSIX requires s_addr to be a single integer value,
whereas Zephyr defines it as an array, and then access as s_addr[0]
everywhere. Fix that by following POSIX definition, which helps to
port existing apps to Zephyr.

Many OSes use values SOCK_STREAM = 1, SOCK_DGRAM = 2, apparently
inherited from the original BSD Unix, which introduced Sockets API.
These values are exposed as numbers in many places, e.g. with a

For stream-based protocols (TCP), adding less data than requested
("short write") is generally not a problem - the rest of data can
be sent in the next packet. So, make net_pkt_append() return length
of written data instead of just bool flag, which makes it closer
to the behavior of POSIX send()/write() calls.
There're many users of older net_pkt_append() in the codebase
however, so net_pkt_append_all() convenience function is added which
keeps returning a boolean flag. All current users were converted to
this function, except for two:
samples/net/http_server/src/ssl_utils.c
samples/net/mbedtls_sslclient/src/tcp.c
Both are related to TLS and implement mbedTLS "tx callback", which
follows POSIX short-write semantics. Both cases also had a code to
workaround previous boolean-only behavior of net_pkt_append() - after
calling it, they measured length of the actual data added (but only
in case of successful return of net_pkt_append(), so that didn't
really help). So, these 2 cases are already improved.

- net_pkt memory management is done through k_mem_slab
- function got introduced or relevantly renamed to target eithe net_pkt
or net_buf fragments.
- net_buf's sent_list ends up in net_pkt now, and thus helps to save
memory when TCP is enabled.

There have been long lasting confusion between net_buf and net_nbuf.
While the first is actually a buffer, the second one is not. It's a
network buffer descriptor. More precisely it provides meta data about a
network packet, and holds the chain of buffer fragments made of net_buf.
Thus renaming net_nbuf to net_pkt and all names around it as well
(function, Kconfig option, ..).
Though net_pkt if the new name, it still inherit its logic from net_buf.

This patch is the first of a serie that will separate completely net_pkt
from net_buf.

Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t. This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.
We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.
We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.
