Make many more headers internal-only.

Fixes for the amalgamation generator for internal headers.

Remove BOTAN_DLL exporting macros from all internal-only headers;
the classes/functions there don't need to be exported, and
avoiding the PIC/GOT indirection can be a big win.

Add missing BOTAN_DLLs where necessary, mostly gfpmath and cvc

For GCC, use -fvisibility=hidden and set BOTAN_DLL to the
visibility __attribute__ to export those classes/functions.
