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.

Additionally, crypto/conf/conf_lib.c needs to include e_os.h to catch
those aliases.

This compiles correctly, but depending on what may be defined, it's
possible that this could fail compilation. The braces are mismatched,
and it's possible to end up with an else followed by another else.
