Store bitmaps and bitmaps always in separate fields in the internal
menu structure.  Get rid of a lot of assumptions in the code that the
menu can have strings only when it is not some other type and that
bitmaps come in two flavors.
Add a lot of conformance tests, including some submitted by Jason
Edmeades.

Moved options from the Makefile into the source.

Send a "DoAction" control event when the user scrolls the text.

Also map AF_UNSPEC sockaddrs in the sockaddr handlers.
Zero initialize the sockaddr in ws_sockaddr_alloc().

Remove spaces before '\n' in traces.

Add some traces to make it easier to debug icon generation problems.

Check the return value of IStream_SetSize in IStream_Read, since
otherwise execution could continue on and cause heap corruption.

BlockChainStream_ReadAt returns a BOOL, not an HRESULT so change
StgStreamImpl_Read to handle this, by returning STG_E_READFAULT on
failure.

The DontWait parameter is used for forcing the function not to wait
for the server to finish.

NULL instead.

Implement ldap_create_page_control{A,W} and
ldap_parse_page_control{A,W}.
Move the page handling functions into their own file.
