Gilles Peskine da0913ba6b Call setbuf when reading or writing files: library
After opening a file containing sensitive data, call mbedtls_setbuf() to
disable buffering. This way, we don't expose sensitive data to a memory
disclosure vulnerability in a buffer outside our control.

This commit adds a call to mbedtls_setbuf() after each call to fopen(),
except:
* In ctr_drbg.c, in load_file(), because this is only used for DH parameters
  and they are not confidential data.
* In psa_its_file.c, in psa_its_remove(), because the file is only opened
  to check its existence, we don't read data from it.

Gilles Peskine 6497b5a1d1 Add setbuf platform function
Add a platform function mbedtls_setbuf(), defaulting to setbuf().

The intent is to allow disabling stdio buffering when reading or writing
files with sensitive data, because this exposes the sensitive data to a
subsequent memory disclosure vulnerability.

To test version negotiation with tls12 OpenSSL/GnuTLS server, If

can work with this case. mbedTLS will fail due to `rsa_pss_rsae_*`
unsupported.
