Hanno Becker 101bcba26f UDP proxy: Allow more than one message to be delayed
Previously, the UDP proxy could only remember one delayed message
for future transmission; if two messages were delayed in succession,
without another one being normally forwarded in between,
the message that got delayed first would be dropped.

This commit enhances the UDP proxy to allow to delay an arbitrary
(compile-time fixed) number of messages in succession.

Hanno Becker a5e68979ca Resolve integer type conversion problem on MSVC
MSVC rightfully complained that there was some conversion from `size_t`
to `unsigned int` that could come with a loss of data. This commit
re-types the corresponding struct field `ctx_buffer::len` to `size_t`.
Also, the function `ctx_buffer_append` has an integer return value
which is supposed to be the (positive) length of the appended data
on success, and a check is inserted that the data to be appended does
not exceed MAX_INT in length.

Hanno Becker fbb0b701e4 Corrupt application data in the beginning instead of the end in UDP proxy
The UDP proxy corrupts application data at the end of the datagram. If
there are multiple DTLS records within the same datagram, this leads
to the wrong message being corrupted. This commit always corrupts the
beginning of the message to prevent this.

Overall, the UDP proxy needs reworking if it is supposed to reliably
support multiple records within a single datagram, because it
determines its actions from the type of the first record in the
current datagram only.

Hanno Becker 1dd62ea811 Add packing option to UDP proxy
This commit provides the new option pack=TIME for the udp proxy
./programs/test/udp_proxy. If used, udp packets with the same
destination will be queued and concatenated for up to TIME
milliseconds before being delivered.

This is useful to test how mbed TLS's deals with multiple DTLS records
within a single datagram.

Andres AG 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'.
