2adb375c50 Add option to avoid 64-bit multiplication
Motivation is similar to NO_UDBL_DIVISION.

The alternative implementation of 64-bit mult is straightforward and aims at
obvious correctness. Also, visual examination of the generate assembly show
that it's quite efficient with clang, armcc5 and arm-clang. However current
GCC generates fairly inefficient code for it.

I tried to rework the code in order to make GCC generate more efficient code.
Unfortunately the only way to do that is to get rid of 64-bit add and handle
the carry manually, but this causes other compilers to generate less efficient
code with branches, which is not acceptable from a side-channel point of view.

So let's keep the obvious code that works for most compilers and hope future
versions of GCC learn to manage registers in a sensible way in that context.

24768bfa37 Improve test_zeroize.gdb breakpoint
Improve the position of the breakpoint to be set at a line of code that
is less likely to be optimised out by the compiler. Setting the breakpoint
at a place that can be easily optimised out by the compiler will cause the
gdb script to fail as it cannot match the source code line to the
compiled code. For this reason the breakpoint is now set at the fclose()
call which is very unlikely to be optimised out or there might be a
resource leak.

ddebc49f28 Add gdb script to test mbedtls_zeroize()
The gdb script loads the programs/test/zeroize program and feeds it as
imput its own source code. Then sets a breakpoint just before the last
program's return code and checks that every element in memory was
zeroized. Otherwise it signals a failure and terminates.

The test was added to all.sh.

15ad579895 Merge tag 'mbedtls-2.8.0' into iotssl-1381-x509-verify-refactor-restricted
Conflict resolution:

* ChangeLog
* tests/data_files/Makefile: concurrent additions, order irrelevant
* tests/data_files/test-ca.opensslconf: concurrent additions, order irrelevant
* tests/scripts/all.sh: one comment change conflicted with a code
  addition. In addition some of the additions in the
  iotssl-1381-x509-verify-refactor-restricted branch need support for
  keep-going mode, this will be added in a subsequent commit.

38d8165865 all.sh: add opposites to all boolean options
All options can now be overridden by a subsequent option, e.g.
"all.sh --foo --no-foo" is equivalent to "all.sh --no-foo". This
allows making wrapper scripts with default options and occasionally
overriding those options when running the wrapper script.

14c3c0610e Test with 32-bit and 64-bit bignum limbs on all architectures
Build with MBEDTLS_HAVE_INT32 and MBEDTLS_HAVE_INT64 on all
architectures, not just x86_64. These two modes should work on all
platforms (except embedded environments where 64-bit division is not
available).

Also run the unit tests.

Correct the description: this is not "N-bit compilation", but "N-bit
bignum limbs".

e963efa110 Don't limit RSA_NO_CRT test in all.sh to 64-bit systems
Compilation and test for the `MBEDTLS_RSA_NO_CRT` option were
previously guarded by a check for 64-bit systems, for which there
is no reason. This commit moves both outside of the guard.

7c6521688a all.sh: --keep-going mode
Add --keep-going mode to all.sh. In this mode, if a test fails, keep
running the subsequent tests. If a build fails, skip any tests of this
build and move on to the next tests. Errors in infrastructure, such as
git or cmake runs, remain fatal. Print an error summary at the end of
the run, and return a nonzero code if there was any failure.

In known terminal types, use color to highlight errors.

On a fatal signal, interrupt the run and report the errors so far.
