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.

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.

If we receive a HTTP request and if the earlier context is still
active and it is not the same as the new one, then close the earlier
one. Otherwise it is possible that the old context will be left into
TCP ESTABLISHED state and would never be released. Example of this
is that we had IPv4 connection active and then IPv6 connection is
established, in this case we will disconnect the IPv4 connection
after this commit.

The mbedtls debugging function was set before the ssl config
struct was initialized. This meant that it was not possible
to activate mbedtls debug prints. This commit sets the debug
print option after the config struct has been initialized.
Fixed also the debug prints which print extra \n which looks
very bad in debugging outputs.
This commit does not enable mbedtls debugging, it just makes it
possible to output mbedtls debug prints. In order to get mbedlts
debug prints one needs to do this:
* set DEBUG_THRESHOLD to >0 in http_server.c
* enable CONFIG_NET_DEBUG_HTTP in project config file
* enable MBEDTLS_DEBUG_C in mbedtls config file (see file pointed
by CONFIG_MBEDTLS_CFG_FILE option)
* in qemu, one needs to increase the size of the available RAM,
this setting does the trick, CONFIG_RAM_SIZE=300

If the user really wants, it is possible to increase the
maximum size of the fragmented packet. According to RFC 2460
chapter 5, we do not need to accept larger than 1500 byte IPv6
packets, so the max pkt limit is set to 2. But if really needed
the limit can be raised by defining NET_IPV6_FRAGMENTS_MAX_PKT
to some new value. Currently there is no Kconfig option for
doing this as it is unlikely that this is needed.
