libibverbs: complete initial implementation
The implementation lacks complete support for all potential threading usage models, but it should support current usage models. The library is about 90% complete, and should be usable by most applications. Missing functionality and complete multi-threading support will be deferred until an application requires it, or a later time.

winverbs: modify how device events are reported
Change reporting device events to simplify interface and avoid missing events. Device events are now set using flags, allowing multiple events to occur in the kernel before userspace retrieves them. This will avoid losing events or userspace needing to call into the kernel to retrieve one event at a time. Events are also associated with a device port, rather than with the device itself.
The new types of events are kept more generic for transport neutral independence.

winverbs: allow synchronous operations
The winverbs library incorrectly calls DeviceIoControl with a NULL overlapped structure. Since the file was opened with overlapped I/O, the results of any DeviceIoControl calls are indetermined, according to the documentation.
The intent of using NULL was to convert from an asynchronous operation to a synchronous call. To fix this, provide a wrapper around DeviceIoControl that can accept a NULL overlapped parameter. If a NULL parameter is used, the call converts to a synchronous operation.
The wrapper is implemeted by adding a base class, CWVBase, that the other classes will derive from. Common functionality and data are moved out of the existing classes and into CWVBase.

indexlist: fix dereferencing NULL pointer
If the indexlist has not grown, then pArray is NULL. Calls to the IndexList API will end up accessing a NULL pointer. To avoid adding checks (pArray != NULL) in the API, allocate an 'EmptyList' index entry that pArray can reference until the first allocation is done.

When using a diff utility to find differences between two subdirectories,
for example, an svn branch and the trunk, you can have the diff program
ignore files. This is useful to avoid diffs caused by object files,
executables, or svn tracking files.
The following file can be fed into diff to have it ignore files that

The current uvp_get_interface() routine takes a structure as input. Included in the structure is a version number. In the winverb branch, I added a new API to take the version as a separate parameter, along with the size of the structure.
A better solution to supporting multiple interfaces is to define interfaces using GUIDs. This not only allows different versions of the same interface (for example the UVP interface), but also provides a mechanism that can be used to add new interfaces without affecting existing ABIs or APIs.
