130b7df2db EVP_*Update: ensure that input NULL with length 0 isn't passed
Even with custome ciphers, the combination in == NULL && inl == 0
should not be passed down to the backend cipher function.  The reason
is that these are the values passed by EVP_*Final, and some of the
backend cipher functions do check for these to see if a "final" call
is made.

Fixes #8675

9437fe0b01 Tolerate 0 byte input length for Update functions
We treat that as automatic success. Other EVP_*Update functions already do
this (e.g. EVP_EncryptUpdate, EVP_DecryptUpdate etc). EVP_EncodeUpdate is
a bit of an anomoly. That treats 0 byte input length as an error.

f426625b6a Prevent over long nonces in ChaCha20-Poly1305
ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input for
every encryption operation. RFC 7539 specifies that the nonce value (IV)
should be 96 bits (12 bytes). OpenSSL allows a variable nonce length and
front pads the nonce with 0 bytes if it is less than 12 bytes. However it
also incorrectly allows a nonce to be set of up to 16 bytes. In this case
only the last 12 bytes are significant and any additional leading bytes are
ignored.

It is a requirement of using this cipher that nonce values are unique.
Messages encrypted using a reused nonce value are susceptible to serious
confidentiality and integrity attacks. If an application changes the
default nonce length to be longer than 12 bytes and then makes a change to
the leading bytes of the nonce expecting the new value to be a new unique
nonce then such an application could inadvertently encrypt messages with a
reused nonce.

Additionally the ignored bytes in a long nonce are not covered by the
integrity guarantee of this cipher. Any application that relies on the
integrity of these ignored leading bytes of a long nonce may be further
affected.

Any OpenSSL internal use of this cipher, including in SSL/TLS, is safe
because no such use sets such a long nonce value. However user
applications that use this cipher directly and set a non-default nonce
length to be longer than 12 bytes may be vulnerable.

3fd5970035 Add support for the SRP base64 alphabet
Historically we used to implement standalone base64 code for SRP. This
was replaced by commit 3d3f21aa with the standard base64 processing code.

However, the SRP base64 code was designed to be compatible with other SRP
libraries (notably libsrp, but also others) that use a variant of standard
base64. Specifically a different alphabet is used and no padding '='
characters are used. Instead 0 padding is added to the front of the string.
By changing to standard base64 we change the behaviour of the API which may
impact interoperability. It also means that SRP verifier files created prior
to 1.1.1 would not be readable in 1.1.1 and vice versa.

Instead we expand our standard base64 processing with the capability to be
able to read and generate the SRP base64 variant.

c080461448 Change SRP functions to use EVP_EncodeUpdate/EVP_DecodeUpdate functions
Previously they were using EVP_EncodeBlock/EVP_DecodeBlock. These are low
level functions that do not handle padding characters. This was causing
the SRP code to fail. One side effect of using EVP_EncodeUpdate is that
it inserts newlines which is not what we need in SRP so we add a flag to
avoid that.
