We can't determine the correct block size until we read the header, and we
can't create the BigBlockFile until we know the correct block size. To
solve this dilemma, have StorageImpl calculate the file size it needs instead
of asking the BigBlockFile to "ensure a big block exists".

This should always be calculated based on the big block size.

Big block sizes can be 512 or 4096, so we define arrays that are large
enough in either case.

Use the actual big block size from the open storage file. Also, remove a
special case that was only used for reading/writing the header.

The header is always 512 bytes, regardless of the big block size.

comdlg32: Removed unused parameters from FILEDLG95_OnWMSize, FILEDLG95_OnWMCommand, and FD32_WMMeasureItem.

wineps.drv: Retrieve the full printer name to avoid truncation when the name is 32 characters or longer.

Since we return success, we should at least make sure the result is not
uninitialized memory.

d3dx9_36: Rename variables in D3DXGetShaderConstantTable(Ex) to match naming convention used in the file.
