Issue 1:
sh.bittable_size is a size_t but i is and int, which can result in
freelist == -1 if sh.bittable_size exceeds an int.
This seems to result in an OPENSSL_assert due to invalid allocation
size, so maybe that is "ok."
Worse, if sh.bittable_size is exactly 1<<31, then this becomes an
infinite loop (because 1<<31 is a negative int, so it can be shifted
right forever and sticks at -1).
Issue 2:
CRYPTO_secure_malloc_init() sets secure_mem_initialized=1 even when
sh_init() returns 0.
If sh_init() fails, we end up with secure_mem_initialized=1 but
sh.minsize=0. If you then call secure_malloc(), which then calls,
sh_malloc(), this then enters an infite loop since 0 << anything will
never be larger than size.
Issue 3:
That same sh_malloc loop will loop forever for a size greater
than size_t/2 because i will proceed (assuming sh.minsize=16):
i=16, 32, 64, ..., size_t/8, size_t/4, size_t/2, 0, 0, 0, 0, ....
This sequence will never be larger than "size".

In some cases, testutil outputs subtests like this:
1..6 # Subtest: progname
The standard set by Test::More (because there really is no actual
standard yet) gives this display:
# Subtest: progname
1..6
Until the standard is actually agreed upon, let's do it like
Test::More.

Add "single part" digest sign and verify functions. These sign and verify

The function SSL_set_SSL_CTX() can be used to swap the SSL_CTX used for
a connection as part of an SNI callback. One result of this is that the
s->cert structure is replaced. However this structure contains information
about any custom extensions that have been loaded. In particular flags are
set indicating whether a particular extension has been received in the
ClientHello. By replacing the s->cert structure we lose the custom
extension flag values, and it appears as if a client has not sent those
extensions.
SSL_set_SSL_CTX() should copy any flags for custom extensions that appear
in both the old and the new cert structure.

TAP:Harness came along in perl 5.10.1, and since we claim to support
perl 5.10.0 in configuration and testing, we can only load it
conditionally.
The main reason to use TAP::Harness rather than Test::Harness is its
capability to merge stdout and stderr output from the test recipes,
which Test::Harness can't. The merge gives much more comprehensible
output when testing verbosely.

Commit c4666bfa changed s_server so that it asked libssl rather than the
underlying socket whether an error is retryable or not on the basis that
libssl has more information. That is true unfortunately the method used
was wrong - it only checks libssl's own internal state rather than both
libssl and the BIO. Should use SSL_get_error() instead.
This issue can cause an infinite loop because some errors could appear as
retryable when in fact they are not.

We now have a version of PEM_read_bytes that can use temporary
buffers allocated from the secure heap; use them to handle this
sensitive information.
Note that for PEM_read_PrivateKey, the i/o still goes through
stdio since the input is a FILE pointer. Standard I/O performs
additional buffering, which cannot be changed to use the OpenSSL
secure heap for temporary storage. As such, it is recommended
to use BIO_new_file() and PEM_read_bio_PrivateKey() instead.

The extended function includes a 'flags' argument to allow callers
to specify different requested behaviors. In particular, callers can
request that temporary storage buffers are allocated from the secure heap,
which could be relevant when loading private key material.
Refactor PEM_read_bio to use BIO_mems instead of BUFs directly,
use some helper routines to reduce the overall function length, and make
some of the checks more reasonable.
