In order to reuse code, the reset() function is used both to handle the
reset HCI command but also to initialize the internal HCI variables when
bringing up the system. In the latter case, avoid setting the reset bit
in the state atomic and signalling the polling API, since that is not
required during initialization.

As a preparation for advanced filtering (Controller-based privacy) this
commit refactors whitelisting so that it becomes its own module and
actually correctly performs state tracking to avoid modifying the
whitelist when it's in use.
Additionally it also removes the duplicate separate entries for
advertising and scanning, since the specification only allows one single
global whitelist singleton.

Add internal functions to read advertiser and scanner filter
policy if the roles are enabled. This is required to
restrict updates to whitelist and resolving lists when
filter policy are being used by the roles.

Under invalid host behavior, trying to start advertising
while already active would corrupt the advertiser context.
This is fixed by having an explicit flag to check whether
advertiser is already running.

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.

Given that K_NO_WAIT is passed as a timeout to net_context_recv(), it's
unlikely this function will return any error value. It's cheap to
check, though, so do it.

This adds shell_exec which can be used to execute commands directly
without the use of a console which is useful for both testing as well
as interfacing with applications/upper layer which would like to have

information, uncompression method should verify CID bit,
SAC and DAC bits and context ID's. But it has missed some

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
