The current names are confusing. Indeed "nexthdr" if the type of the
header currently processed, while "next_nexthdr" is the nexthdr field of
the current header.
Rename them to improve readability and make it less error-prone.

ICMPv6 error messages are not sent (on native_posix) because the first
net_pkt_write() returns an error.
pkt has just been allocated using net_pkt_alloc_with_buffer(). Trying to
write an empty packet in overwrite mode will result in an error. There
is no need to be in overwrite mode, since we want to write the LL
src/dst addresses at the beginning.

The Counter resource in the IPSO Push Button object was incremented
silently by the post write handler of the State resource. This prevented
the resource from being marked as updated, effectively preventing
the engine from sending notifications to observers.
Fix this, by setting the new counter value with `lwm2m_engine_set_u64()`
instead. This will update the resource value, and trigger the engine to
send notifications if needed.

HTTP_DATA_FINAL was incorrectly notified in case Content Length field
was present in the HTTP respone - in such case it was set for every
response fragment, not only the last one.
Fix this by relying on `message_complete` flag instead of
`http_should_keep_alive()` function to determine whether to notify
HTTP_DATA_FINAL or not. As the HTTP parser calls the
`on_message_complete()` callback in either case (response is chunked or
not), this seems to be a more reasonable apporach to determine whether
the fragment is final or not.
Additinally, instead of calling response callback for
`on_body`/`on_message_complete` separately, call it directly from
`http_wait_data()` function, after the parsing round. This fixes the
case when headers were not reported correctly when the provided buffer
was smaller than the total headers length, resulting in corrupted data
being reported to the user.

There were several issues preventing JSON format writes to work
correctly:
1. The formatter wrongly assumed that Base Name and Relative Name values
read from the message are NULL terminated, which in result could give
invalid results when combining them.
2. The formatter wrongly assumed that Relative Name is always present,
which is not always the case. In result, it failed to parse messages,
which contained full path in their Base Name Field
3. There were no boundaries check when reading JSON variable name/value,
which could lead to buffer overflow in case malformed data was
received.

According to the specificaion, resources are not predefined to use 32 or
64 bit floating point numbers, but should rather accept any of them (as
indicated by the size of the TLV in the message). This lead to issues
for instance with Eclipse Leshan LWM2M server, where Leshan sent 64-bit
value, while Zephyr expected 32-bit, making it impossible to write
the resource.
Therefore, unify the float usage to 32-bit float representation and fix
the TLV parsing functions, to accept values sent as either 32 or 64 bit
float.

The `poll()` function did not report POLLHUP if the peer ended the DTLS
session, making it impossible to detect such event on the application
side.
On the other hand, TLS erroneusely reported POLLHUP along with each
POLLIN event, as the 0 returned by the `recv()` socket call was
wrongly interpreted (it was expected to get 0 in return as 0 bytes were
requested).
Fix this by introducing a helper function to process the mbedtls context
and verify if new application data is pendingi or session has ended.
Use this new function in the poll handler, instead of a socket `recv()`
call, to remove any ambiguity in the usage, for both TLS and DTLS.

Since it's not possible to encode full range of 64-bit unsigned integer,
remove this type from the LwM2M implementation, and replace its uses
with 64-bit signed integer.
Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>
As the resource values represented by the unsigned integers were casted
to integers of a corresponding size in the read handler, they were not
ecoded properly if the unsigned value was larger than the maximum
integer value of the corresponding size (i.e. they were encoded as
negative values).
Fix this by casting the unsinged value to a wider integer type, to
prevent incorrect interpratetion of the data provided. The TLV encoding
functions take care of the optimization (i. e. encoding integers on the
minimum number of bytes needed), so it should prevent bandwith waste if
the unsigned value would actually fit into the integer of the
corresponding size.
Similar case is for the write hander, where unsigned integers encoded at
8 bytes were not processed correctly. Fix this by using wider decoder as
well.

By default ICMP desination unreachable error packets are generated when
input packets target ports that are not in a listening state. This not
only reveals the presence of the host on the network which may be
considered a security vulnerability depending on the application, it
also ends up triggering ARP lookups to respond to the sending host. With
a small ARP table and a network where there may be broadcast (or
multicast) service discovery traffic such as mDNS or uPnP, ARP table
thrashing can occur impacting network stack performance.
