98d3a67a5c Simplify the coverage statistics summary 
The script was parsing the output from `make lcov` to extract numbers and
calculate percentages. But everything including the percentages is already
present in the output of `make lcov`, just with a slightly different
presentation. So replace all this by a simple extraction of the relevant
lines from the output of `make lcov`.

This is more robust than the previous code, which relied on `tail -n4` to
extract relevant lines, which broke when `make lcov` started to emit one
extra line at the end.

a57cf9813a Implement and test mbedtls_mpi_mod_raw_random 
In the basic/XXX=core test cases, use odd upper bounds, because the mod
version of random() only supports odd upper bounds (the upper bound is a
modulus and the mod modules only support odd moduli).

881447d411 Move bignum helpers to their own module 
Move bignum-related helper functions to their own files under tests/include
and tests/src. The primary motivation is that a subsequent commit will make
bignum_helpers.h include library/bignum*.h, but we want to be able to
include <test/helpers.h> without having the library directory on the include
path (we do this in some programs under programs/ intended for testing).

acdefdd51a Unify RNG initialization that must be unified 
mpi_core_random_basic and mpi_random_values must generate the same random
sequences in order to get the expected test coverage (where we know we'll
hit certain numbers of retries). Facilitate this by defining the RNG seed
only once.

Fix the seed to explicitly list all 16 words of the key. This isn't strictly
required (missing initializer fields get the value zero), but it's clearer.
