The current wave tests only use a single header for playback.  Tests
have been added to use multiple headers and to reuse them.  This is
how streaming applications and direct sound use the wave api.

This should make it easier to add encryption tests later.

- implemented NtQueryInformationThread's ThreadDescriptorTableEntry
  information class
- used it to implement the kernel32's equivalent (GetThreadSelectorEntry)

- implemented ntdll.NtQueryInformationFile's FilePipeLocalInformation control code 
- reimplemented kernel32.GetNamedPipeInfo on top of it
- enhance current features to make this work both on client and server handles
- now also returning the number of instances

Thanks to Juan Lang for catching this one.

Implement NdrFullPointerFree.

rpcrt4: Implement remaining part of NdrFullPointerQueryPointer and implement NdrFullPointerInsertRefId.

Add some tests.

crypt32: Implement CertVerifyCRLTimeValidity and partially implement CertVerifySubjectCertificateContext.

ComputeConformanceOrVariance it is still necessary to set the count
variable to the value retrieved.
