To allow hardware crypto acceleration custom mbedtls library needs to be
prepared. However current implementation forces the default library to
be used.
This patch allows not using the default library and passing custom
mbedtls target to use with openthread.

Currently, functions for poll sock_fds array management are buggy, in
case there is another socket open (for instance the socket for firmware
update download), it could get overwritten, if the LwM2M socket was
closed and re-opened in a meantime (e. g. on registration timeout).
Fix this, by appending new entries to the sock_fds in continuous manner.
In case of removal, the deleted entry is overwritten by the last one,
and the last one is cleared.

During FW update, the application expects a consecutive data stream.
Therefore retransmitted blocks shall not be forwarded to the
application, but ignored. In case blocks are received out of order,
return an error and do not handle this block.

When FW update in PUSH mode is used, the firmware is encapsulated in the
TLV as an opaque data, according to the LMWM2M satandard, and then
sliced into blocks and transferred block by block in several
transactions. Therefore, the TLV header is only present in the initial
message.
Current implementation did not handle this case well, reporting errors
on consecutive blocks, therefore making the FW update in PUSH mode
broken.
This commit fixes this issue with following changes:
* The TLV is only assumed to be present in the initial block, while
consecutive blocks will be processed directly into the appropriate
handler,
* 32-bit variables shall be used whenever dealing with the opaque data
length, since the firmware size can easily exceed the 16-bit range,
* Additional information, required for the FW block transfer to work
properly were added to the block context structure,
* The application shall only be notified of the actual data length, and
not the total block size (the total TLV size including header).

`addrlen` parameter is updated on each `recvfrom` call, indicating the
actual address length returned. In case both, IPv4 and IPv6 are used on
different sockets (i. e. on regular LWM2M socket and FOTA socket), the
returned address length will differ.
In case `from_addr_len` is not reinitialized on each iteration, the
value stored in the `from_addr_len` variable will eventually indicate
the smaller IPv4 address size, therefore resulting in a failure in a
consecutive call on an IPv6 socket.

There is already a variable 'network_protos_up', which stores number of
network protocols being up. Additionally each network protocol has its
own state represented by is_ip{,v6}cp_up. Use the latter in FSM up() and
down() callbacks.
This fixes a case when both IPCP and IPv6CP protocols are going
down. When using ctx->is_network_up only one of them (the first) was
deinitialized correctly, second stayed always up (at least partially,
e.g. not calling ppp_network_down()).

OpenThread BR can assign addresses via DHCPv6 or when acting as an
NCP, addresses can be added manually. Currently, those addresses are
handled in the same way as auto-configured addresses.
This patch maps the newly introduced mAddressOrigin of otNetifAddress to
Zephyr's net_addr_type.
This way an application can register a handler and differentiate by type
of assignment:
```
static void handler(struct net_mgmt_event_callback *cb,
u32_t mgmt_event,
struct net_if *iface)
{
if (iface->config.ip.ipv6->unicast[i].addr_type == NET_ADDR_DHCP) {
