This commit adds comments to bio_method_st definitions where the
function pointers are defined as NULL. Most of the structs have comments
but some where missing and not all consitent.

I noticed that some of the BIO_METHOD structs are placing the name on
the same line as the type and some don't. This commit places the name
on a separate line for consistency (which looks like what the majority
do)

Move the the BIO_METHOD and BIO structures into internal header files,
provide appropriate accessor methods and update all internal code to use
the new accessors where appropriate.

Undo unapproved commit that removed DJGPP and WATT32

DJGPP is no longer a supported platform.  Remove all #ifdef, etc.,
cases that refer to it.  DJGPP also #define'd WATT32, so that
is now removed as well.

Windows 8 SDKs complain that GetVersion() is deprecated.

We only use GetVersion like this:

	(GetVersion() < 0x80000000)

which checks if the Windows version is NT based. Use a macro check_winnt()
which uses GetVersion() on older SDK versions and true otherwise.

This change includes all the name changes needed throughout all C files.
