FAQ update to mention Applink.

Note that debug and release libraries are NOT interchangeable.  If you

built OpenSSL with /MD your application must use /MD and cannot use /MDd.

As per 0.9.8 the above limitation is eliminated for .DLLs. OpenSSL

.DLLs compiled with some specific run-time option [we recommend the

default /MD] can be deployed with application compiled with different

option or even different compiler. But there is a catch! Instead of

re-compiling OpenSSL toolkit, as you would have to with prior versions,

you have to compile small C snippet with compiler and/or options of

your choice. The snippet gets installed as

<install-root>/include/openssl/applink.c and should be either added to

your project or simply #include-d in one [and only one] of your source

files. Failure to do either manifests itself as fatal "no

OPENSSL_Applink" error.
