Fixes a missing mutex unlock on an out of memory error

This patch version slightly deviates from the original patch to OP-TEE
since we don't call `XFREE(NULL)` as there exist implementations of
`free()` that don't support it.

Clang creates now DWARFv5 debug infos which isn't supported in old Valgrind
versions. Instruct Clang to create DWARFv4 debug infos, so we can run our
tests in Valgrind.

If we allow the length to be 0, we should also prepare for the case where
the user doesn't want to provide a valid input-data pointer.

In case of EME-PKCS1-v1_5 decoding, the encoded message
format is as follow : EM = 0x00 || 0x02 || PS || 0x00 || M.
When using an empty message, the 0x00 octet that separates
the padding string and message is located at the end. Thus,
update the condition to pass the check in case of empty message.
This fixes the following AOSP cts test:
Module: CtsKeystoreTestCases
Test: testEmptyPlaintextEncryptsAndDecrypts

The code-path via the `ed25519ph_*()` APIs would have allowed to get here
and de-reference `ctx` even if it is `NULL`.

It's a compile-only test, but we run it anyways so we can finally get
`crypt_fsa()` included in the coverage report. It's not really useful but
also doesn't hurt.

A user isn't guaranteed to use the `der_..._multi()` in a correct fashion.
Therefor change the pattern in the library and terminate further vararg
processing immediately after the `EOL` marker is hit.
The previous changes introducing the function-`attribute(sentinel)` would
allow detecting this, but not all compilers have support for the attribute.

`NULL` as defined by the standard is not guaranteed to be of a pointer
type. In order to make sure that in vararg API's a pointer type is used,
define our own version and use that one internally.

* The RFC doesn't limit the context to be a string.
It talks about `octets` which means it could be any binary data.
* Move the context-preprocessing function out of tweetnacl.c
* Fix potential segfaults when Ed25519 signature verification fails and
`LTC_CLEAN_STACK` is enabled.
* Fix all the warnings.
* Update documentation.

In case when the signature is not verified the "mlen" variable
is equal to ULONG_MAX. When LTC_CLEAN_STACK has been defined
this results in a segmentation fault.

Previously it was not detected if `inlen` itself was too big and would
overflow the multiplication by 8.
