The function SSL_check_chain() can be used by applications to check that
a cert and chain is compatible with the negotiated parameters. This could
be useful (for example) from the certificate callback. Unfortunately this
function was applying TLSv1.2 sig algs rules and did not work correctly if
TLSv1.3 was negotiated.
We refactor tls_choose_sigalg to split it up and create a new function
find_sig_alg which can (optionally) take a certificate and key as
parameters and find an appropriate sig alg if one exists. If the cert and
key are not supplied then we try to find a cert and key from the ones we
have available that matches the shared sig algs.

A local 'make clean' did some sweeping removals of files execpt for
the .git directory. This is a little too sweeping, as other dotted
files might be cleaned away if they happen to match the pattern that's
searched for.
An example is a symlink .dir-locals.el that would keep disappearing if
you build in the source tree and do a make clean...
So we change this to leave all dotted files alone. Our builds do not
produce such files anyway, so this is a harmless (or rather, less
harmful) change.

A default digest of SHA256 was being returned for RSA PSS even if the
PSS parameters indicated a different digest must be used. We change this
so that the correct default digest is returned and additionally mark this
as mandatory for PSS.
This bug had an impact on sig alg selection in libssl. Due to this issue
an incorrect sig alg might be selected in the event that a server is
configured with an RSA-PSS cert with parameter restrictions.

At some point in the past do_ssl3_write() used to return the number of
bytes written, or a value <= 0 on error. It now just returns a success/
error code and writes the number of bytes written to |tmpwrit|.
The SSL_MODE_RELEASE_BUFFERS code was still looking at the return code
for the number of bytes written rather than |tmpwrit|. This has the effect
that the buffers are not released when they are supposed to be.

tls_parse_stoc_key_share was generating a new EVP_PKEY public/private
keypair and then overrides it with the server public key, so the
generation was a waste anyway. Instead, it should create a
parameters-only EVP_PKEY.
(This is a consequence of OpenSSL using the same type for empty key,
empty key with key type, empty key with key type + parameters, public
key, and private key. As a result, it's easy to mistakenly mix such
things up, as happened here.)

Mingw config targets assumed that resulting programs and libraries are
installed in a Unix-like environment and the default installation
prefix was therefore set to '/usr/local'.
However, mingw programs are installed in a Windows environment, and
the installation directories should therefore have Windows defaults,
i.e. the same kind of defaults as the VC config targets.
A difficulty is, however, that a "cross compiled" build can't figure
out the system defaults from environment the same way it's done when
building "natively", so we have to fall back to hard coded defaults in
that case.
Tests can still be performed when cross compiled on a non-Windows
platform, since all tests only depend on the source and build
directory, and otherwise relies on normal local paths.

The rand pool support allocates maximal sized buffers -- this is typically
12288 bytes in size. These pools are allocated in secure memory which is a
scarse resource. They are also allocated per DRBG of which there are up to two
per thread.
This change allocates 64 byte pools and grows them dynamically if required.
64 is chosen to be sufficiently large so that pools do not normally need to
grow.
