The test used 3DES as the suite for SSLv3, which now makes the handshake fails
with "no ciphersuite in common", failing the test as well. Use Camellia
instead (as there are not enough AES ciphersuites before TLS 1.2 to
distinguish between the 3 versions).

Document some dependencies, but not all. Just trying to avoid introducing new
issues by using a new cipher here, not trying to make it perfect, which is a
much larger task out of scope of this commit.

This was an unused variable when compiling with parameter validation
but without ecp_restartable

When all.sh invokes check_headers_in_cpp, a backup config.h exists. This
causes a stray difference vs cpp_dummy_build.cpp. Fix by only collecting
the *.h files in include/mbedtls.

Force using IPv4 in the GNU_CLI SRTP tests, as introduced for
other tests in #1918.

Since `gnutls-cli` resolves `localhost` as an IPv6 address, and the server
is bound to IPv4 address, gnutl-cli fails to negotiate DTLS sessions.
Force the server to bind to IPv6 address, as a workaround.

Add some interoperability tests with openssl and gnutls, in ssl-opts.sh.

1. Add DTLS-SRTP tests in `ssl-opts.sh`
2. Add logs for the tests to filter.
3. Add function to get the profile informations.

Valgrind is what it does. `memcheck` is how it's implemented.

Wildcard patterns now work with command line COMPONENT arguments
without --except as well as with. You can now run e.g.
`all.sh "check_*` to run all the sanity checks.

The deletion of "$OUT_OF_SOURCE_DIR" had mistakenly been lumped
together with Yotta and then removed when Yotta support was removed.
Bring it back.

After backing up and restoring config.h, `git diff-files` may report
it as potentially-changed because it isn't sure whether the index is
up to date. Use `git diff` instead: it actually reads the file.

It's all about tool detection.

Don't require openssl, mingw, etc. if we aren't going to run a
component that uses them.

Only look for armcc if component_build_armcc is to be executed,
instead of requiring the option --no-armcc.

You can still pass --no-armcc, but it's no longer required when
listing components to run. With no list of components or an exclude
list on the command line, --no-armcc is equivalent to having
build_armcc in the exclude list.

Build the list of components to run in $RUN_COMPONENTS as part of
command line parsing. After parsing the command line, it no longer
matters how this list was built.

Extract the list of available components by looking for definitions of
functions called component_xxx. The previous code explicitly listed
all components in run_all_components, which opened the risk of
forgetting to list a component there.

Add a conditional execution facility: if a function support_xxx exists
and returns false then component_xxx is not executed (except when the
command line lists an explicit set of components to execute).

MAKEFLAGS was set to -j if it was already set, instead of being set if
not previously set as intended. So now all.sh will do parallel builds
if invoked without MAKEFLAGS in the environment.

Don't bail out of all.sh if the OS isn't Linux. We only expect
everything to pass on a recent Linux x86_64, but it's useful to call
all.sh to run some components on any platform.

In all.sh, always run both MemorySanitizer and Valgrind. Valgrind is
slower than ASan and MSan but finds some things that they don't.

Run MSan unconditionally, not just on Linux/x86_64. MSan is supported
on some other OSes and CPUs these days.

Use `all.sh --except test_memsan` if you want to omit MSan because it
isn't supported on your platform. Use `all.sh --except test_memcheck`
if you want to omit Valgrind because it's too slow.

Make the test scripts more portable (tested on FreeBSD): don't insist
on GNU sed, and recognize amd64 as well as x86_64 for `uname -m`. The
`make` utility must still be GNU make.

Call `set disable-randomization off` only if it seems to be supported.
The goal is to neither get an error about disable-randomization not
being supported (e.g. on FreeBSD), nor get an error if it is supported
but fails (e.g. on Ubuntu).

Only fiddle with disable-randomization from all.sh, which cares
because it reports the failure of ASLR disabling as an error. If a
developer invokes the Gdb script manually, a warning about ASLR
doesn't matter.

Use `cmake -D CMAKE_BUILD_TYPE=Asan` rather than manually setting
`-fsanitize=address`. This lets cmake determine the necessary compiler
and linker flags.

With UNSAFE_BUILD on, force -Wno-error. This is necessary to build
with MBEDTLS_TEST_NULL_ENTROPY.

Only whitespace changes in this commit.

In all.sh, always save config.h before running a component, instead of
doing it manually in each component that requires it (except when we
forget, which has happened). This would break a script that requires
config.h.bak not to exist, but we don't have any of those.

Allow the list to use wildcards, e.g. you can run the sanity checks with
all.sh --except "test_*" "build_*"

Add an option to list the available components.

This is not useful yet, but a subsequent commit will add the ability
to run specific components.

Call cleanup from run_component instead of calling it from each
individual component function.

Clean up after each component rather than before. With the new
structure it makes more sense for each component to leave the place
clean. Run cleanup once at the beginning to start from a clean slate.
