Add EFX types and enums to alext.h
...
The types and enums are in efx.h, which is included by alext.h. It's done this
way because EFX has a lot if definitions which would polute alext.h

Fix for MSVC
...
MSVC won't accept zero-sized arrays at the end of structs, if that struct is
used in another struct that's not also at the end. This wastes a float for each

Make the filter history buffer size flexible
...
This lets the filter history buffer be as big as needed for a given use, so
that it can have a size large enough for the more demanding cases, but not be
wasteful for lesser-demanding cases, while not incuring the overhead of an
added pointer indirection
