44bfbe3b95 Update copyright notices to use Linux Foundation guidance
As a result, the copyright of contributors other than Arm is now

Also remove the now-redundant lines declaring that the files are part of
MbedTLS.

Backport 2.7: Unify the example programs' termination

a08652233d Unify the example programs' termination
This is done to account for platforms, for which we want custom behavior
upon the program termination, hence we call `mbedtls_exit()` instead of
returning from `main()`.

For the sake of consistency, introduces the modifications have been made
to the test and utility examples as well. These, while less likely to be
used in the low level environments, won't suffer from such a change.

a58b04649b Add negative test for hard reconnect cookie check
The server must check client reachability (we chose to do that by checking a
cookie) before destroying the existing association (RFC 6347 section 4.2.8).
Let's make sure we do, by having a proxy-in-the-middle inject a ClientHello -
the server should notice, but not destroy the connection.

7bac1ab38a UDP proxy: Don't attempt to dissect dgram into records when dropping
To prevent dropping the same message over and over again, the UDP proxy
test application programs/test/udp_proxy _logically_ maintains a mapping
from records to the number of times the record has already been dropped,
and stops dropping once a configurable threshold (currently 2) is passed.

However, the actual implementation deviates from this logical view
in two crucial respects:
- To keep the implementation simple and independent of
  implementations of suitable map interfaces, it only counts how
  many times a record of a given _size_ has been dropped, and
  stops dropping further records of that size once the configurable
  threshold is passed. Of course, this is not fail-proof, but a
  good enough approximation for the proxy, and it allows to use
  an inefficient but simple array for the required map.
- The implementation mixes datagram lengths and record lengths:
  When deciding whether it is allowed to drop a datagram, it
  uses the total datagram size as a lookup index into the map
  counting the number of times a package has been dropped. However,
  when updating this map, the UDP proxy traverses the datagram
  record by record, and updates the mapping at the level of record
  lengths.

Apart from this inconsistency, the current implementation suffers
from a lack of bounds checking for the parsed length of incoming
DTLS records that can lead to a buffer overflow when facing
malformed records.

This commit removes the inconsistency in datagram vs. record length
and resolves the buffer overflow issue by not attempting any dissection
of datagrams into records, and instead only counting how often _datagrams_
of a particular size have been dropped.

There is only one practical situation where this makes a difference:
If datagram packing is used by default but disabled on retransmission
(which OpenSSL has been seen to do), it can happen that we drop a
datagram in its initial transmission, then also drop some of its records
when they retransmitted one-by-one afterwards, yet still keeping the
drop-counter at 1 instead of 2. However, even in this situation, we'll
correctly count the number of droppings from that point on and eventually
stop dropping, because the peer will not fall back to using packing
and hence use stable record lengths.

788aa4a812 Rename net.{c,h} to net_sockets.{c,h}
The library/net.c and its corresponding include/mbedtls/net.h file are
renamed to library/net_sockets.c and include/mbedtls/net_sockets.h
respectively. This is to avoid naming collisions in projects which also
have files with the common name 'net'.
