28474f41a0 RSA PSS: remove redundant check; changelog 
Remove a check introduced in the previous buffer overflow fix with keys of

511bb84c60 RSA: Fix another buffer overflow in PSS signature verification

operation results in an all-zero buffer. This could happen at any key size.

55db24ca50 RSA: Fix buffer overflow in PSS signature verification 
Fix buffer overflow in RSA-PSS signature verification when the hash is
too large for the key size. Found by Seth Terashima, Qualcomm.

Added a non-regression test and a positive test with the smallest
permitted key size for a SHA-512 hash.

4491a791be Parse Signature Algorithm ext when renegotiating 
Signature algorithm extension was skipped when renegotiation was in
progress, causing the signature algorithm not to be known when
renegotiating, and failing the handshake. Fix removes the renegotiation
step check before parsing the extension.

77359c93e4 DHM: Fix dhm_check_range() always returning 0 
Although the variable ret was initialised to an error, the
MBEDTLS_MPI_CHK macro was overwriting it. Therefore it ended up being
0 whenewer the bignum computation was successfull and stayed 0
independently of the actual check.

8af7bfa982 Improve behaviour on fatal errors 
If we didn't walk the whole chain, then there may be any kind of errors in the
part of the chain we didn't check, so setting all flags looks like the safe
thing to do.

3df4e4e1d0 Prevent signed integer overflow in CSR parsing 
Modify the function x509_csr_parse_der() so that it checks the parsed
CSR version integer before it increments the value. This prevents a
potential signed integer overflow, as these have undefined behaviour in
the C standard.
