Streamline HB_NO_CFF

Remove HB_VECTOR_SIZE

It was cumbersome to get it to work reliably, for dubious performance
gain, mostly in the subsetter maybe...

Life is easier without.  It was disabled forever anyway.

Add hb_bitwise_neg

Remove accidentally left cruft

Remove (unused) posix_memalign fallback

Was wrong.  The returned pointer couldn't be passed to free().  Ouch!

[ci] Test no build system builds

Introduced in aa3450c, let's preserve it

Fix cmake build

Hopefullly.

[config] Don't compile disabled features

This makes it possible to include all .cc files into build, even if not
building CoreText, Uniscribe, etc.

This was mostly to help custom builders.  But also means that we can
include all files in our own build system.  Not sure if we should.
Definitely simplifies things, but slightly only.

[config] Flesh out CONFIG.md

Part of https://github.com/harfbuzz/harfbuzz/issues/1652

Minor

[config] Replace HAVE_FALLBACK with HB_NO_FALLBACK_SHAPE

This disables fallback shaper in tiny builds.  Projects that don't
use our build system and want to disable fallback shaper (eg. Firefox)
should define HB_NO_FALLBACK_SHAPE now.

Part of https://github.com/harfbuzz/harfbuzz/issues/1652

Add CONFIG.md

https://github.com/harfbuzz/harfbuzz/issues/1652

Minor

Use injected class name

Disable non-OpenType kerning with hb-ft in HB_TINY

Deprecate v_kerning callback again

Part of https://github.com/harfbuzz/harfbuzz/issues/1682

Minor

Partially revert "[ft/ot] Remove implementation of deprecated kerning funcs"

This reverts commit 47030b1855f04c0d75899ffb6f5021fea3c19b90.

Reverts only the hb-ft part, to reinstate non-OpenType kerning with
FreeType.

Fixes https://github.com/harfbuzz/harfbuzz/issues/1682

Revert "Deprecate font kern API"

This reverts commit d219f899f4b2fb4b39ebc1dff9fb648fc5d6d112.

API change: Un-deprecate font kern API.

Part of https://github.com/harfbuzz/harfbuzz/issues/1682

We should document that this API is only necessary to hook up
non-OpenType kerning.  hb-ot-font will continue to NOT implement them.

Canonically reorder U+0C55 and U+0C56

enable cff subset tests

add Unicode UCS-4 cmap
fix Unicode bits in OS/2
add Unicode cmap sub-table in SourceHanSans-Regular_subset.otf
regenerate cff subset test expected results

[cff] minor format (#1774)

Remove 'mym3'

change assert(false) to failure

Fix typo :)

Move HB_NO_SETLOCALE to closer place to its to unbreak HB_TINY build (#1768)

Add HB_NO_OEPN (#1767)

Add HB_NO_SETLOCALE

Remove round polyfill

Added in 01dff1e and 19256bef, this was targeted at older
msvc versions that don't support C99 but now as we require
C++11 we don't target places those envs thus removing this.

Simplify HB_PARTIALIZE impl

+this works on gcc 4.8 as well as default code path.

Revert "Test new solution for HB_PARTIALIZE"

This reverts commit a0c4900799c26e4ff34180842a5ff21048fe31a0.

Test new solution for HB_PARTIALIZE

Just testing bots.  Will finish based on results.

[ci] Use HB_OPTIMIZE_SIZE instead of __OPTIMIZE_SIZE__

[ci] Test -Os and optimize size in Alpine bot

__OPTIMIZE_SIZE__ should be defined whenever -Os but some Internet thread
indicate may not so lets do that ourselves as that is the main intention

minor, add HB_USE_INTERNAL_QSORT

The only thing I need for a working wasm in a minimum libc,
otherwise I have to provide the very same qsort inside that libc

[ci] remove wine from fedora bot

We are not testing Windows exes in fedora mingw bot, we don't have to as
probably won't go that smoothly and we have real Windows bots anyway
and as wine installation itself is time taking let's remove it

[stat] minor format
