Always create sub-blobs in MEMORY_MODE_READONLY
This fixes a design bug with sanitize and sub-blobs that can
cause crashes. Jonathan and I found and debugged this issue
when we tested a corrupt font with the md5sum / filename:
ea395483d37af0cb933f40689ff7b60a. Two hours of intense
debugging we found out that the font has overlapping GSUB/GPOS
tables, and as such, sanitizing the second table can modify
the first one, which can cause all kinds of undefined behavior.
The correct way to fix this is to make sure sub-blobs are
always created readonly, since we consider the parent blob
to be a shared resource and can't modify it, even if it *is*
writable.
This essentially makes the READONLY_MAY_MAKE_WRITABLE mode
unused... Maybe we should simply remove / deprecate it.

Remove public enum names again
As was reported to me, glib-mkenum does not understand named enums,
so remove for now.

all our enums.

Make it an error to include non-top-level headers
Users should #include <hb.h> (or hb-ft.h, hb-glib.h, etc), but
never things like hb-shape.h directly. This makes it easier to
refactor headers later on without breaking compatibility.

[HB] Remove HB_MEMORY_MODE_READONLY_NEVER_DUPLICATE
Unlike the rest of the memory-mode enum, this one didn't only
describe the access mode of the input memory region. Remove it.
If someone wants to inhibit duplicating, they can lock the blob
and throw away the key.
Based on mailing list discussion with Carl Worth.
