20607bb0fa Fix macroization of inline in C++ 
When compiling as C++, MSVC complains about our macroization of a keyword.
Stop doing that as we know inline is always available in C++

59efb6a1b9 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
CHARS_TO_LIMB(s >> 1) but the solution implemented looks more robust with
respect to future code changes.

a701d2f5e9 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

1c38550bbd Skip to trusted certs early in the chain 
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
performance but also to avoid false negatives (eg an old root being no longer
trusted while the newer intermediate is directly trusted).

15f1088ef6 Add tests for verify callback 
As we're about to change the chain construction logic, we want to make sure
the callback will still be called exactly when it should, and not on the
(upcoming) ignored certs in the chain.
