Provide a number of functions to allow parameters to be set and
retrieved in a type safe manner. Functions are provided for many
integral types plus double, BIGNUM, UTF8 strings and OCTET strings.
All of the integer functions will widen the parameter data as
required. This permits a degree of malleability in the parameter
definition. For example a type can be changed from a thirty two bit
integer to a sixty four bit one without changing application code.
Only four and eight byte integral sizes are supported here.
A pair of real functions are available for doubles.
A pair of functions is available for BIGNUMs. These accept any sized
unsigned integer input and convert to/from a BIGNUM.
For each OCTET and UTF8 strings, four functions are defined. This
provide get and set functionality for string and for pointers to
strings. The latter avoiding copies but have other inherent risks.
Finally, some utility macros and functions are defined to allow
OSSL_PARAM definition arrays to be specified in a simple manner.
There are two macro and one function for most types. The exception
being BIGNUM, for which there is one macro and one function.

The OSSL_PARAM attribute names |buffer| and |buffer_size| may lead to

rename |buffer| and |buffer_size| to |data| and |data_size|

Two tests are added, one that tests the internal API, the other tests
the public API. Those two tests both test the same provider, which
acts both as a built-in provider and as a loadable provider module.

Adding a provider means creating an internal provier object and adding
it to the store. This allows the addition of built in providers, be it
in the OpenSSL libraries or in any application.
"Loading" a provider is defined broadly. A built in provider is already
"loaded" in essence and only needs activating, while a provider in a
dynamically loadable module requires actually loading the module itself.
In this API, "loading" a provider does both.

The previous commit fixed an underflow that may occur in ecp_nistp521.c.
This commit adds a test for that condition. It is heavily based on an
original test harness by Billy Brumley.

The function felem_diff_128_64 in ecp_nistp521.c substracts the number |in|
from |out| mod p. In order to avoid underflow it first adds 32p mod p
(which is equivalent to 0 mod p) to |out|. The comments and variable naming
suggest that the original author intended to add 64p mod p. In fact it
has been shown that with certain unusual co-ordinates it is possible to
cause an underflow in this function when only adding 32p mod p while
performing a point double operation. By changing this to 64p mod p the
underflow is avoided.
It turns out to be quite difficult to construct points that satisfy the
underflow criteria although this has been done and the underflow
demonstrated. However none of these points are actually on the curve.
Finding points that satisfy the underflow criteria and are also *on* the
curve is considered significantly more difficult. For this reason we do
not believe that this issue is currently practically exploitable and
therefore no CVE has been assigned.
This only impacts builds using the enable-ec_nistp_64_gcc_128 Configure
option.
With thanks to Bo-Yin Yang, Billy Brumley and Dr Liu for their significant
help in investigating this issue.

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.
