Manuel Pégourié-Gonnard 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.

Manuel Pégourié-Gonnard 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
