f4569b14c4 Fix bug checking pathlen on first intermediate 
Remove check on the pathLenConstraint value when looking for a parent to the
EE cert, as the constraint is on the number of intermediate certs below the
parent, and that number is always 0 at that point, so the constraint is always
satisfied.

The check was actually off-by-one, which caused valid chains to be rejected
under the following conditions:
- the parent certificate is not a trusted root, and
- it has pathLenConstraint == 0 (max_pathlen == 1 in our representation)

fixes #280

bc5e508855 Fix other int casts in bounds checking

Fix boolean values according to DER specs 
In BER encoding, any boolean with a non-zero value is considered as
TRUE. However, DER encoding require a value of 255 (0xFF) for TRUE.

This commit makes `mbedtls_asn1_write_bool` function uses `255` instead
of `1` for BOOLEAN values.

With this fix, boolean values are now reconized by OS X keychain (tested
on OS X 10.11).

Fixes #318.

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.

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.

c1b46d0242 Fix bug in server parsing point formats extension 
This bug becomes noticeable when the extension following the "supported point

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.

eef142d753 Depend on ECJPAKE key exchange, not module 
This is more consistent, as it doesn't make any sense for a user to be able to
set up an EC J-PAKE password with TLS if the corresponding key exchange is
disabled.

Arguably this is what we should de for other key exchanges as well instead of
depending on ECDH_C etc, but this is an independent issue, so let's just do
the right thing with the new key exchange and fix the other ones later. (This
is a marginal issue anyway, since people who disable all ECDH key exchange are
likely to also disable ECDH_C in order to minimize footprint.)

f7022d1131 Fix bug in server parsing point formats extension 
There is only one length byte but for some reason we skipped two, resulting in
reading one byte past the end of the extension. Fortunately, even if that
extension is at the very end of the ClientHello, it can't be at the end of the
buffer since the ClientHello length is at most SSL_MAX_CONTENT_LEN and the
buffer has some more room after that for MAC and so on. So there is no
buffer overread.

Possible consequences are:
- nothing, if the next byte is 0x00, which is a comment first byte for other
  extensions, which is why the bug remained unnoticed
- using a point format that was not offered by the peer if next byte is 0x01.
  In that case the peer will reject our ServerKeyExchange message and the
handshake will fail.
- thinking that we don't have a common point format even if we do, which will
  cause us to immediately abort the handshake.
None of these are a security issue.

The same bug was fixed client-side in fd35af15

f472179d44 Adjust dependencies for EC extensions 
The Thread spec says we need those for EC J-PAKE too.
However, we won't be using the information, so we can skip the parsing
functions in an EC J-PAKE only config; keep the writing functions in order to
comply with the spec.

ea5370d4a2 Don't allow reconnect during handshake 
Especially for resumed handshake, it's entirely possible for an epoch=0
ClientHello to be retransmitted or arrive so late that the server is already
at epoch=1. There is no good way to detect whether it's that or a reconnect.

However:
- a late ClientHello seems more likely that client going down and then up
  again in the middle of a handshake
- even if that's the case, we'll time out on that handshake soon enough
- we don't want to break handshake flows that used to work
So the safest option is to not treat that as a reconnect.

This helps in the case where an intermediate certificate is directly trusted.
In that case we want to ignore what comes after it in the chain, not only for

Assume we have two trusted CAs with the same name, the first uses ECDSA 256
bits, the second RSA 2048; cert is signed by the second. If we do the keysize
check before we checked the key types match, we'll raise the badkey flags when
checking the EC-256 CA and it will remain up even when we finally find the
correct CA. So, move the check for the key size after signature verification,
which implicitly checks the key type.

0761733c1b Fix potential NULL dereference 
We document that either of recv or recv_timeout may be NULL, but for TLS we
always used recv... Thanks Coverity for catching that.
(Not remotely trigerrable: local configuration.)

Also made me notice net_recv_timeout didn't do its job properly.

bcf13bab5d Fix issue with MemSan and entropy 
Due to the recent change about entropy sources strength, it is no longer
acceptable to just disable the platform source. So, instead "fix" it so that
it is clear to MemSan that memory is initialized.

I tried __attribute__((no_sanitize_memory)) and MemSan's blacklist file, but
couldn't seem to get them to work.
