all.sh restores **/Makefile from git in case the version in the worktree was
from doing a cmake in-tree build. Instead of doing this unconditionally, do
it only if the toplevel Makefile seems to have been automatically
generated (by cmake or otherwise, e.g. by mbedtls-prepare-build). This way
all.sh no longer silently wipes changes made to Makefile but not committed yet.

Back up the config files at the beginning of all.sh, rather than before each
component. In particular, create the backup before running cleanup for the
first time. This fixes#3139 (all.sh using a config.h.bak from a previous
job), and makes all.sh more robust against accidentally using a modified
config.h midway through because a component messed with the backup.
Use a different extension (*.all.bak rather than *.bak) for the backups.
This is necessary to ensure that auxiliary scripts such as depends*.pl that
make their own backup don't remove all.sh's backup, which the code from this
commit does not support.

Generate programs/test/cpp_dummy_build.cpp dynamically instead of
maintaining it manually. This removes the need to update it when the list of
headers changes.
Include all the headers unconditionally except for the ones that cannot be
included directly.
Support this dynamic generation both with make and with cmake.
Adapt all.sh accordingly. Remove the redundant C build from
component_build_default_make_gcc_and_cxx (it was also done in
component_test_default_out_of_box), leaving a component_test_make_cxx. Also
run the C++ program, because why not. Do this in the full configuration
which may catch a bit more problems in headers.
Fixes#2570 for good.

Tests for psa_cipher_encrypt and psa_cipher_decrypt functions.
The psa_cipher_encrypt function takes no parameter for IV and always generates
it therefore there will be a randomness in the calculation and cannot be
validated by comparing the actual output with the expected output.
The function is tested by:
- doing a prtially randomized test with an encryption then a decryption
and validating the input with output of the decryption
- validating against the multipart encryption
The combination of this two methods provides enough coverage like a
known answer test.

A test case for which the loop would take practically forever if it was

The test case should cause the CI to time out if starting with the
current code, ecp_check_pubkey_mx() was changed to call
ecp_check_pubkey_x25519() first and run the mbedtls_mpi_size(() test
afterwards, which would make no semantic difference in terms of memory

Without this parameter, it would be hard for callers to know how many bytes

We were already rejecting them at the end, due to the fact that with the
usual (x, z) formulas they lead to the result (0, 0) so when we want to
normalize at the end, trying to compute the modular inverse of z will
give an error.
If we wanted to support those points, we'd a special case in
ecp_normalize_mxz(). But it's actually permitted by all sources
(RFC 7748 say we MAY reject 0 as a result) and recommended by some to
reject those points (either to ensure contributory behaviour, or to
protect against timing attack when the underlying field arithmetic is
not constant-time).
Since our field arithmetic is indeed not constant-time, let's reject
those points before they get mixed with sensitive data (in
ecp_mul_mxz()), in order to avoid exploitable leaks caused by the
special cases they would trigger. (See the "May the Fourth" paper
