Remove deprecated functions before 1.0

[szhorvat]

Old deprecated functions should be removed before the 1.0 release.

Add functions that shouldn't be removed, or whose removal needs discussion, to the following list (with a short reasoning):

All of these seem okay to me, no reason not to remove them.

[szhorvat]

@krlmlr @Antonov548 Let us know if the removal of any of these would cause an issue for R/igraph

[krlmlr]

@Antonov548: can you please do a quick grep exercise in src/interface.c and src/interface_extra.c ?

[szhorvat]

@krlmlr The compiler should give warnings when you use a deprecated function (unless this was disabled—I don't remember). There was one deprecation I can recall since the last R release.

Please ignore the following, which will only become deprecated in 1.0:

igraph_interface.h
146:IGRAPH_DEPRECATED IGRAPH_EXPORT igraph_error_t igraph_delete_vertices_idx(

[Antonov548]

As long as I remember it was disabled.
