Dave Rodgman fa40b02da3 Remove use of lstat 
lstat is not available on some platforms (e.g. Ubuntu 16.04). In this
particular case stat is sufficient.

Eduardo Silva e1bfffc4f6 x509_crt: handle properly broken links when looking for certificates 
On non-windows environments, when loading certificates from a given
path through mbedtls_x509_crt_parse_path() function, if a symbolic
link is found and is broken (meaning the target file don't exists),
the function is returning MBEDTLS_ERR_X509_FILE_IO_ERROR which is
not honoring the default behavior of just skip the bad certificate file
and increase the counter of wrong files.

The problem have been raised many times in our open source project
called Fluent Bit which depends on MbedTLS:

https://github.com/fluent/fluent-bit/issues/843#issuecomment-486388209

The expected behavior is that if a simple certificate cannot be processed,
it should just be skipped.

This patch implements a workaround with lstat(2) and stat(2) to determinate
first if the entry found in the directory is a symbolic link or not, if is
a simbolic link, do a proper stat(2) for the target file, otherwise process
normally. Upon find a broken symbolic link it will increase the counter of
not processed certificates.

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.
