a40f0f6475 Add sparse array data type.
This commit adds a space and time efficient sparse array data structure.
The structure's raw API is wrapped by inline functions which provide type
safety.

77550dbf7a Build cleanup: Remove the VMS hack from test/build.info
There was a hack specifically for VMS, which involved setting a make
variable to indicate that test/libtestutil contains a 'main'.

Instead, we use the new attributes 'has_main' to indicate this, and
let the VMS build file template fend with it appropriately.

c6048af23c Fix a memory leak in the mem bio
If you use a BIO and set up your own buffer that is not freed, the
memory bio will leak the BIO_BUF_MEM object it allocates.

The trouble is that the BIO_BUF_MEM is allocated and kept around,
but it is not freed if BIO_NOCLOSE is set.

The freeing of BIO_BUF_MEM was fairly confusing, simplify things
so mem_buf_free only frees the memory buffer and free the BIO_BUF_MEM
in mem_free(), where it should be done.

Alse add a test for a leak in the memory bio
Setting a memory buffer caused a leak.

b3023ced6b Windows: Produce a static version of the public libraries, always
When building shared libraries on Windows, we had a clash between
'libcrypto.lib' the static routine library and 'libcrypto.lib' the
import library.

We now change it so the static versions of our libraries get '_static'
appended to their names.  These will never get installed, but can
still be used for our internal purposes, such as internal tests.

When building non-shared, the renaming mechanism doesn't come into
play.  In that case, the static libraries 'libcrypto.lib' and
'libssl.lib' are installed, just as always.

Fixes #7492

f01344cb5c Do not reset SNI data in SSL_do_handshake()
PR #3783 introduce coded to reset the server side SNI state in
SSL_do_handshake() to ensure any erroneous config time SNI changes are
cleared. Unfortunately SSL_do_handshake() can be called mid-handshake
multiple times so this is the wrong place to do this and can mean that
any SNI data is cleared later on in the handshake too.

Therefore move the code to a more appropriate place.

2de108dfa3 Save and restore the Windows error around TlsGetValue.
TlsGetValue clears the last error even on success, so that callers may
distinguish it successfully returning NULL or failing. This error-mangling
behavior interferes with the caller's use of GetLastError. In particular
SSL_get_error queries the error queue to determine whether the caller should
look at the OS's errors. To avoid destroying state, save and restore the
Windows error.

Fixes #6299.

efe749c840 Refuse to run test_cipherlist unless shared library matches build
test/cipherlist_test.c is an internal consistency check, and therefore
requires that the shared library it runs against matches what it was
built for.  test/recipes/test_cipherlist.t is made to refuse running
unless library version and build version match.

This adds a helper program test/versions.c, that simply displays the
library and the build version.

082193ef2b Fix issues in ia32 RDRAND asm leading to reduced entropy
This patch fixes two issues in the ia32 RDRAND assembly code that result in a
(possibly significant) loss of entropy.

The first, less significant, issue is that, by returning success as 0 from
OPENSSL_ia32_rdrand() and OPENSSL_ia32_rdseed(), a subtle bias was introduced.
Specifically, because the assembly routine copied the remaining number of
retries over the result when RDRAND/RDSEED returned 'successful but zero', a
bias towards values 1-8 (primarily 8) was introduced.

The second, more worrying issue was that, due to a mixup in registers, when a
buffer that was not size 0 or 1 mod 8 was passed to OPENSSL_ia32_rdrand_bytes
or OPENSSL_ia32_rdseed_bytes, the last (n mod 8) bytes were all the same value.
This issue impacts only the 64-bit variant of the assembly.

This change fixes both issues by first eliminating the only use of
OPENSSL_ia32_rdrand, replacing it with OPENSSL_ia32_rdrand_bytes, and fixes the
register mixup in OPENSSL_ia32_rdrand_bytes. It also adds a sanity test for
OPENSSL_ia32_rdrand_bytes and OPENSSL_ia32_rdseed_bytes to help catch problems
of this nature in the future.

9d75dce3e1 Add TLSv1.3 post-handshake authentication (PHA)
Add SSL_verify_client_post_handshake() for servers to initiate PHA

Add SSL_force_post_handshake_auth() for clients that don't have certificates
initially configured, but use a certificate callback.

Update SSL_CTX_set_verify()/SSL_set_verify() mode:

* Add SSL_VERIFY_POST_HANDSHAKE to postpone client authentication until after
the initial handshake.

* Update SSL_VERIFY_CLIENT_ONCE now only sends out one CertRequest regardless
of when the certificate authentication takes place; either initial handshake,
re-negotiation, or post-handshake authentication.

Add 'RequestPostHandshake' and 'RequirePostHandshake' SSL_CONF options that
add the SSL_VERIFY_POST_HANDSHAKE to the 'Request' and 'Require' options

Add support to s_client:
* Enabled automatically when cert is configured
* Can be forced enabled via -force_pha

Add support to s_server:
* Use 'c' to invoke PHA in s_server
* Remove some dead code

Update documentation

Update unit tests:
* Illegal use of PHA extension
* TLSv1.3 certificate tests

DTLS and TLS behave ever-so-slightly differently. So, when DTLS1.3 is
implemented, it's PHA support state machine may need to be different.
Add a TODO and a #error

Update handshake context to deal with PHA.

The handshake context for TLSv1.3 post-handshake auth is up through the
ClientFinish message, plus the CertificateRequest message. Subsequent
Certificate, CertificateVerify, and Finish messages are based on this
handshake context (not the Certificate message per se, but it's included
after the hash). KeyUpdate, NewSessionTicket, and prior Certificate
Request messages are not included in post-handshake authentication.

After the ClientFinished message is processed, save off the digest state
for future post-handshake authentication. When post-handshake auth occurs,
copy over the saved handshake context into the "main" handshake digest.
This effectively discards the any KeyUpdate or NewSessionTicket messages
and any prior post-handshake authentication.

This, of course, assumes that the ID-22 did not mean to include any
previous post-handshake authentication into the new handshake transcript.
This is implied by section 4.4.1 that lists messages only up to the
first ClientFinished.

a1df06b363 This has been added to avoid the situation where some host ctype.h functions
return true for characters > 127.  I.e. they are allowing extended ASCII
characters through which then cause problems.  E.g. marking superscript '2' as
a number then causes the common (ch - '0') conversion to number to fail
miserably.  Likewise letters with diacritical marks can also cause problems.

If a non-ASCII character set is being used (currently only EBCDIC), it is
adjusted for.

The implementation uses a single table with a bit for each of the defined
classes.  These functions accept an int argument and fail for
values out of range or for characters outside of the ASCII set.  They will
work for both signed and unsigned character inputs.
