Behdad Esfahbod ed972d5d73 [iter] Rewrite test functions
Notably, add hb_is_source_of(,) and hb_is_sink_of(,) to replace most
uses of hb_is_iterator_of(,).

Behdad Esfahbod 726002a6a6 [iter] Make hb_is_iterator_of() check is_convertible
Instead of is_cr_convertible.

Behdad Esfahbod 5da3c9c33f [iter] Fix hb_zip() end condition
We should compare-equal to end if either iterator's end reaches,
not if both reach at the same time.  Fixes infinite-loop in test
which was happening after hb_enumerate() switched to using hb_zip().

Behdad Esfahbod 7675d0d3a6 [iter] Add hb_range()
hb_range() is like Python range.  hb_iota() has slightly different API.
Ie. it takes a start, instead of end.

Behdad Esfahbod af571dbffc [meta] Replace most hb_enable_if with hb_requires
They do absolutely same thing.  hb_requires is to encode constraints,
whereas hb_enable_if is for more conditional enabling.

Behdad Esfahbod a98e4068e7 Revert "Hide symbols in hb-iter"
This reverts commit 98f14c4cdb.

Same as previous commit.

Behdad Esfahbod 98f14c4cdb Hide symbols in hb-iter
Painful.  All template methods need to be explicitly hidden :(.

Maybe we should switch to -fvisibility=hidden pragma.

A LOT more to go.

Behdad Esfahbod 2bd2750234 [iter] Tweak SFINAE again

Behdad Esfahbod d419a9a437 [iter] Use different SFINAE scheme to make MSVC happy
From Orvid King: TLDR; MSVC has some issues using sizeof(declval<T>()) for
SFINAE of templated types, so I just used SFINAE in a different context where
MSVC doesn't have the issue.

Behdad Esfahbod 42ab32cbba [iter] Remove passing pointer to hb_iter()
While doable with hb_deref_pointer() as well, we also would then
need to do it in a ton of places.  Not worth it / messy.

Behdad Esfahbod b6f29bf141 [iter] Accept pointers in hb_iter()
No idea how to avoid dupicating code.  Was hoping hb_deref_pointer()
would do it, but looks like a pointer can't bind to a universal
reference T&&.  Humm.
