Simon Butcher e7f96f22ee Merge fix IOTSSL-475 Potential buffer overflow
Two possible integer overflows (during << 2 or addition in BITS_TO_LIMB())
could result in far too few memory to be allocated, then overflowing the
buffer in the subsequent for loop.

Both integer overflows happen when slen is close to or greater than
SIZE_T_MAX >> 2 (ie 2^30 on a 32 bit system).

Note: one could also avoid those overflows by changing BITS_TO_LIMB(s << 2) to
CHARS_TO_LIMB(s >> 1) but the solution implemented looks more robust with
respect to future code changes.

Manuel Pégourié-Gonnard 58fb49531d Fix potential buffer overflow in mpi_read_string()
Found by Guido Vranken.

Two possible integer overflows (during << 2 or addition in BITS_TO_LIMB())
could result in far too few memory to be allocated, then overflowing the
buffer in the subsequent for loop.

Both integer overflows happen when slen is close to or greater than
SIZE_T_MAX >> 2 (ie 2^30 on a 32 bit system).

Note: one could also avoid those overflows by changing BITS_TO_LIMB(s << 2) to

Manuel Pégourié-Gonnard faee44ded1 Avoid false positives in bounds check
The size of the buffer already accounts for the extra data before the actual
message, so the allowed length is SSL_MAX_CONTENT_LEN starting from _msg

Manuel Pégourié-Gonnard f592e8eaf6 Update yotta dependency version
We've had a bit of a race between us adapting to changes in 0.3.x and the
sockets author reverting those changes in the 0.3.x line and pushing them to
0.4.0. Let's use the newest and greatest sockets :)

Manuel Pégourié-Gonnard d0d8cb36a4 Cache ClientHello extension
This extension is quite costly to generate, and we don't want to re-do it
again when the server performs a DTLS HelloVerify. So, cache the result the
first time and re-use if/when we build a new ClientHello.

Note: re-send due to timeouts are different, as the whole message is cached
already, so they don't need any special support.

Manuel Pégourié-Gonnard c1b46d0242 Fix bug in server parsing point formats extension
This bug becomes noticeable when the extension following the "supported point
formats" extension has a number starting with 0x01, which is the case of the
EC J-PAKE extension, which explains what I noticed the bug now.

This will be immediately backported to the stable branches,
see the corresponding commits for impact analysis.
