* Simplify names of some ebpf_result codes
* Remove _ERROR_ for consistency
* Combine EBPF_INVALID_HANDLE and EBPF_INVALID_OBJECT
* Rename EBPF_ERROR_NOT_FOUND to EBPF_KEY_NOT_FOUND for consistency with the associated description.
* Change code that returned EBPF_ERROR_NOT_FOUND for a case other than a
key, to use a different appropriate result, so the description stays correct.
Fixes#212

* Pinning a program requires a name to pin to
* The load program API doesn't correctly deal with an empty section name
(it does use the first section but then tells the execution context
that the section name is empty instead of the chosen one), so for now
require the section name in any "add program" command
* Allow netsh to hold references on multiple programs
* Fix handle leak in "show programs"
* Implement ability to pin a program, but unpinning requires
a way to look up what a program was pinned to, and no such
API exists currently.
* Implement filtering "show programs" output by filename and section

Since the program type changed from int to GUID the display has been
broken (it displays a useless pointer value). This fix makes it display
the string name of the type.

The IDL was generating MIDL2279 because it used const on an [out] param,
which is warned against since RPC marshaling copies the result into new
memory. See https://marc.info/?l=ms-dcom&m=103440617317922 for some
discussion.
Other changes should hopefully be obvious.
