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.

Clang is nice enough to support bitwise operators on __m128i, but MSVC
isn't.
Also, __cpuid() in MSVC comes from <intrin.h> (which is included via
<emmintrin.h>), not <cpuid.h>.

As of this commit, to use the intrinsics for MBEDTLS_AESNI_C:
* With MSVC, this should be the default.
* With Clang, build with `clang -maes -mpclmul` or equivalent.
* With GCC, build with `gcc -mpclmul -msse2` or equivalent.
In particular, for now, with a GCC-like compiler, when building specifically
for a target that supports both the AES and GCM instructions, the old
implementation using assembly is selected.
This method for platform selection will likely be improved in the future.

The configuration symbol MBEDTLS_AESNI_C requests AESNI support, but it is
ignored if the platform doesn't have AESNI. This allows keeping
MBEDTLS_AESNI_C enabled (as it is in the default build) when building for
platforms other than x86_64, or when MBEDTLS_HAVE_ASM is disabled.
To facilitate maintenance, always use the symbol MBEDTLS_AESNI_HAVE_CODE to
answer the question "can I call mbedtls_aesni_xxx functions?", rather than
repeating the check `defined(MBEDTLS_AESNI_C) && ...`.

Uncrustify indents
```
asm("foo"
HELLO "bar"
"wibble");
```
but we would like
```
asm("foo"
HELLO "bar"
"wibble");
```
Make "bar" an argument of the macro HELLO, which makes the indentation from
uncrustify match the semantics (everything should be aligned to the same
column).

function is called wherever we need to free the entry.
