* Add option to pin all programs added and show links and maps
* "add programs" now supports the equivalent of bpftool's "prog loadall"
in addition to just "prog load"
* add "show links" netsh command
* expose "show maps" netsh command. It was partially implemented but
never exposed before.
* remove ebpf_map_query_definition() and test as being redundant with
bpf_obj_get_info_by_fd() (and in the future, a strongly typed one that
is map specific but different from the query map definition prototype)
* Fix bug where getting the next ID failed to check for index beyond
array size. And add test cases for it.
* Fix bug in ebpf_state.c where after enough tests ran it would start
returning EBPF_NO_MEMORY because _ebpf_state_next_index was never
reset.
Addresses #549

* Add netsh capability to unpin programs
* The netsh "set program id=<id> pinned=" (with no value) will now unpin a
program from all paths
* The netsh "delete program <id>" will now unpin a program from all
paths before and releasing any reference held by netsh itself
* Make the "attached=<string>" argument to netsh set programs work
with a section name like string
* Add libbpf api bpf_obj_get()
* Add ebpf_get_next_pinned_program_name() API to enumerate pinned
programs
Fixes#190#373
This is required for #188 which will update the "show programs"
and also add an option to "add program" to pin all programs rather
than just the first one in a file, like bpftool has such an option.

* Update mock netsh behavior since PR 540 changed the underlying requirements
PreprocessCommand now correctly matches tags so you can specify a later
optional tag without having to specify earlier optional tags
Signed-off-by: Dave Thaler <dthaler@microsoft.com>
* Add libpf's libbpf_prog_type_by_name() API
And add an ebpf_get_program_type_by_name() that returns the GUIDs
instead of ints.
This also removes the hard-coding of GUIDs or ints from the netsh
helper.
