rpcrt4: Free the memory allocated for the protseq and endpoint strings allocated in RpcServerUseProtseq* functions.

Make a copy of the protseq string in alloc_serverprotoseq to simplify
memory management in higher-level functions.

However, on some buggy platforms it returns
RPC_S_INVALID_ENDPOINT_FORMAT. Don't follow this behaviour our
implementation of the API.

We have the version already in the header of the winetest results.

Checked by the IE8 install.

Fix for office 2007 proofing tools installer.

mpeg3_streamsize must estimate the number of samples of an mp3 chunk. 
The result must be block aligned (PCM) or frame aligned (MP3).

Some fields should be redundant now, eg. gl_vtx_type and glType. I'll leave
that for a different patch to fix though.

Wined3d doesn't need it since it already has the element count.

wined3d: Separate the internal representation of vertex declaration elements from the struct used to create it.

Internally we want to store some extra data, like ffp_valid. One of the later
patches also stores the format desc in the declaration elements, instead of
the current WINED3DDECLTYPE.

It's never used.
