comctl32: Added input validation to TOOLTIPS_GetTextW() in order to handle gracefully the case where it is called with an empty tooltip.

wineps.drv: Make sure we call CreateFontIndirect with zero width, otherwise we'll get a scaled-width font.

Use TLB_MultiByteToBSTR to allocate import library entry name in
ITypeLib2_Constructor_MSFT as BSTR instead of a normal block of memory
to make the allocator the same as for SLTG typelibs. Free the name
with SysFreeString instead of TLB_Free.

rpcrt4: Fix RpcStringBindingComposeA/W and RpcStringBindingParseA/W to escape and unescape delimiters in the string binding.

This behaviour is stated by the DCE/RPC specification and is also
shown in the rpcrt4 conformance tests.

rpcrt4: Print a warning if connecting to a named pipe failed in rpcrt4_conn_open_pipe in the !wait case.

The epm tower for the ncalrpc protseq should have a floor with a
protid of EPM_PROTOCOL_PIPE instead of EPM_PROTOCOL_SMB.

rpcrt4: Fix crash in rpcrt4_ncalrpc_parse_top_of_tower due to unconditionally dereferencing networkaddr and endpoint variables.

These can be NULL when parts of the tower are not required.

The size depends on the length of the endpoint string, not the network
address string.

rpcrt4: Re-implement part of the conformant varying structure processing routines using array_* functions.

This allows conformant string array types to be
marshalled/unmarshalled when embedded in a complex type.
