We can call memcpy() with a pointer 1 past the last allocated byte and length
of 0 and you can argue that that's undefined behaviour.

- If we have a maximum amount of characters permitted to be printed
(for example "%.2s", which allows for a maximum of 2 chars), we
minimize the number of characters from the string to printed to
that size.
- If there is space for padding and there is a maximum amount of
characters to print (for example "%3.2s", which shall give at
least a 1 space padding), the amount of characters to pad with
gets added to the maximum so the minimum field size (3 in this
example) gets filled out.

Visual C version from version 2003 complain about certain function
names, for example:
apps\apps.c(2572) : warning C4996: 'open': The POSIX name for this item is deprecated. Instead, use the ISO C++ conformant name: _open. See online help for details.
This adds preprocessor aliases for them in e_os.h.

those aliases.

The function InitOnceExceuteOnce is the best way to support the
implementation of CRYPTO_THREAD_run_once() on Windows. Unfortunately
WinXP doesn't have it. To get around that we had two different
implementations: one for WinXP and one for later versions. Which one was
used was based on the value of _WIN32_WINNT.
This approach was starting to cause problems though because other parts of
OpenSSL assume _WIN32_WINNT is going to be 0x0501 and crashes were
occurring dependant on include file ordering. In addition a conditional
based on _WIN32_WINNT had made its way into a public header file through
commit 5c4328f. This is problematic because the value of this macro can
vary between OpenSSL build time and application build time.
The simplest solution to this mess is just to always use the WinXP version
of CRYPTO_THREAD_run_once(). Its perhaps slightly sub-optimal but probably
not noticably.

Giving setbuf() a 64-bit pointer isn't faulty, as the argument is
passed by a 64-bit register anyway, so you only get a warning
(MAYLOSEDATA2) pointing out that only the least significant 32 bits
will be used.
However, we know that a FILE* returned by fopen() and such really is a
32-bit pointer (a study of the system header files make that clear),
so we temporarly turn off that warning when calling setbuf().

Since with SSL_VERIFY_NONE, the connection may continue and the
session may even be cached, we should save some evidence that the
chain was not sufficiently verified and would have been rejected
with SSL_VERIFY_PEER. To that end when a CT callback returs failure
we set the verify result to X509_V_ERR_NO_VALID_SCTS.
Note: We only run the CT callback in the first place if the verify
result is still X509_V_OK prior to start of the callback.
