9c09326572 mpi_mod_exp: be pedantic about right shift
The window size starts giving diminishing returns around 6 on most
platforms and highly unlikely to be more than 31 in practical use cases.
Still, compilers and static analysers might complain about this and
better to be pedantic.

3646ff02ad mpi_exp_mod: move X next to the precomputed values
With small exponents (for example, when doing RSA-1024 with CRT, each
prime is 512 bits and we'll use wsize = 5 which may be smaller that the
maximum - or even worse when doing public RSA operations which typically
have a 16-bit exponent so we'll use wsize = 1) the usage of W will have
pre-computed values, then empty space, then the accumulator at the very
end.

Move X next to the precomputed values to make accesses more efficient
and intuitive.

844614814e mpi_exp_mod: remove memory ownership confusion
Elements of W didn't all have the same owner: all were owned by this
function, except W[x_index]. It is more robust if we make a proper copy
of X.

b764ee1603 mpi_exp_mod: protect out of window zeroes
Out of window zeroes were doing squaring on the output variable
directly. This leaks the position of windows and the out of window
zeroes.

Loading the output variable from the table in constant time removes this
leakage.

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.

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.
