mbedtls_mpi_add_mpi() and mbedtls_mpi_sub_mpi() have the same logic, just
with one bit to flip in the sign calculation. Move the shared logic to a new
auxiliary function. This slightly reduces the code size (if the compiler
doesn't inline) and reduces the maintenance burden.

In development, mbedtls/version.h is getting included indirectly
in via mbedtls/build_info.h, but this doesn't happen in 2.28.
This commit add this dependency in ssl_test_lib.h

Although our build scripts support that, it's annoying, because it makes
"test_suite_XXX" ambiguous between "all the data for
test_suite_XXX.function" and "just test_suite_XXX.data".

It just got renamed, and it's also not the most canonical example since it's
a somewhat deprecated interface in the development branch. Make a different
module the example.

Align the name of the bignum test suite with the source module (which was
renamed from mpi.c to bignum.c in the PolarSSL 1.x days). This also brings
it into line with the test suites for the low-level bignum interfaces.

The transport is allowed to be MBEDTLS_SSL_TRANSPORT_DATAGRAM when the
compression is MBEDTLS_SSL_COMPRESS_NULL.

Looking for executables causes problems with leftover compiled test
suites from other branches when we forget to run make clean before
switching branches. Using the .data files is more robust as most of them
are tracked, so will be removed when switching branches.

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.

Change is_compression_ok() to is_compression_bad() for more semantics
that are a better match for what's really going on in the case of no
compression support.

For the benefit of auto-formatting tools, move from the '$placeholder'
templating syntax to a new syntax of the form:
__MBEDTLS_TEST_TEMPLATE__PLACEHOLDER
This change allows the test code template to be almost entirely valid C.
