The warning is only correct if the assembly code for AESNI is built, not if
MBEDTLS_AESNI_C is activated but MBEDTLS_HAVE_ASM is disabled or the target
architecture isn't x86_64.
This is a partial fix for #7236.

Sphinx's breathe plugin cannot readily parse the Mbed TLS macros, so
define the less essential ones away at the doxygen step to reduce the
number of warnings.

When passed an empty OID, mbedtls_oid_get_numeric_string would read one
byte from the zero-sized buffer and return an error code that depends on
its value. This is demonstrated by the test suite changes, which
check that an OID with length zero and an invalid buffer pointer does
not cause Mbed TLS to segfault.
Also check that second and subsequent subidentifiers are terminated, and
add a test case for that. Furthermore, stop relying on integer division
by 40, use the same loop for both the first and subsequent
subidentifiers, and add additional tests.

ssl_helpers.c is treated with W3 warning level in MSVC complier.
So that it's reported as error for warning of conversion from
size_t to int. This change fixes all this type of warning seen in
Microsoft Visual Studio 12.0. Besides, some potential problems of
type conversion are also handled.

During test of component build_arm_linux_gnueabi_gcc_arm5vte and
build_arm_none_eabi_gcc_m0plus. It fails with
- error: implicit declaration of function
‘test_fail_if_psa_leaking’
It happens because test_fail_if_psa_leaking is defined in
helpers.function. This block of code is not converted into C code
while compiling ssl_helpers.c. The function has been moved to
psa_crypto_helpers.c in order to fix this build error.

tests/src/ssl_helpers.c depends on functions defined
in library/*.c. If it's complied as an OBJECT with other c files,
cmake complains undefined reference in link stage under programs/.
Therefore, tests/src/test_helpers/ is created to hold c files with
dependency of library/*.c. Besides, tests/src/test_helper/*.c is
separated into another OBJECT, mbedtls_test_helpers, as sources
to build all test suite executables.
In addition, everest header directory is included in case
MBEDTLS_ECDH_VARIANT_EVEREST_ENABLED is enabled.

Since we move many functions from test_suite_ssl.function to
ssl_helpers.c in commit bd56b03. This causes various of
build errors. This commit fixes all the build errors by
- including header files
- providing function definition
- adding guards for typedef statements and functions

The block cipher exception affects both remote and local timing attacks.
Move them to the Caveats section and reference it from both the local

Originally for the sake of simplicity there was a single category for
software based attacks, namely timing side channel attacks.
Be more precise and categorise attacks as software based whether or not
they rely on physical information.

Some functions are renamed in commit c463849. This change moves all

test_suite_ssl.function contains many functions that are used to set
up a TLS connection. To reduce its file size, those functions would
be moved to ssl_helpers.c under tests/src. As the start of this
implementation, some necessary header files are moved in advance.

When MBEDTLS_USE_PSA_CRYPTO is enabled, the application must call
psa_crypto_init() before directly or indirectly calling cipher or PK code
that will use PSA under the hood. Document this explicitly for some
functions.
To avoid clutter, this commit only documents the need to call
psa_crypto_init() in common, non-obvious cases: using a PK object that was
not constructed using PSA, X.509 processing, or setting up an SSL context.
Functions that are normally only called after such a function (for example,
using a cipher or PK context constructed from a PSA key), or where the need
for PSA is obvious because they take a key ID as argument, do not need more
explicit documentaion.
