496601e504 [docs] (2/2) Fix generation of API documentation (#56745). 
Creating the API Reference in the (new) `reference' sub-directory is
consistent with other documentation sub-topics, such as `design',
`glyphs' and `tutorial'.

This patch fixes broken hyperlinks in the documentation pointing to
and from the API Reference.  It also allows web assets to load from
their relative paths.

* builds/freetype.mk (DOC_DIR): Adjust.
(refdoc, refdoc-venv): Add `--site' argument.

* builds/toplevel.mk (do-dist): Updated.

26d0f579c0 * include/freetype/internal/ftmemory.h (FT_OFFSET): New macro. 
Use this for `base + offset' pointer calculations where `base' can
be NULL (triggering a sanitizer warning even if the resulting
pointer gets never dereferenced since it is undefined behaviour
in C).
