Behdad Esfahbod 2d39031f7b [buffer/set/map] Move immutable check only to C API boundary
The immutable objects are a concept only enforced by the C API.
So move checks only to that region.

This does assume that the rest of the code is careful not getting
into these internal methods on immutable objects, which something
we do, but have no way of enforcing (currently).

Behdad Esfahbod 505b3fc6cf [harfbuzz.cc] Fix OffsetTable name clash with Mac headers
There's no easy way to undo a "using namespace" in our sources, so by the time
we get to include hb-coretext.cc from harfbuzz.cc, we already have "using namespace OT"
active, which clashes with Mac headers.

Garret Rieger 8f47dd5779 [subset] don't set lookup visited in closure_lookups_context_t::recurse.
- Lookup::closure_lookups also checks if the lookups visited and sets the lookup to visited. If we set visited in 'recurse' then Lookup::closure_lookups will fail to recurse into the children of the lookup.
- Also when copying ChainRule's skip LookupRecord's that point to lookups which aren't retained. This matches FontTool's behaviour.

Dominik Röttsches a5f6f869e8 Drop layout table if layout lookup accelerator allocation failed
If the table is kept, when the table is present but only the accelerator
allocation failed, then we run into nullptr dereferences downstream in
hb_ot_map_t::apply when trying to access proxy.accels[i].

To fix this, instead of only setting lookup_count of accelerator_t
itself, drop the whole table to avoid hb-ot-map construction assuming
that the lookups will work correctly despite accelerator allocation
having failed.

David Corbett dec52006d9 Map BCP 47 tags to all macrolanguages
The general rule is that if a BCP 47 macrolanguage maps to an OpenType
language system tag, all its individual languages map to it too.
Previously, a tag like "prs" (Dari) would not map to the language system
tag ('FAR ') of its macrolanguage ("fa") because "prs" already has its
own language system tag ('DRI '). That exception has been removed: now
"prs" maps to 'DRI ' and falls back to 'FAR '.

This is beneficial for reproducible builds, as build paths can vary
between builds.

Ross Burton 5aff83104e [build] generate hb-version.h once at configure time with Meson
Currently with Meson hb-version.h is generated during the build without
any explicit dependencies which can result in build failures due races
over the file.

Change this to be generated at configure time, so that the file is always
generated once before the build itself.

Closes #2667

Ross Burton bc1c93fbe0 [build] No need to pass source directory to gen-hb-version
The input file is by definition in the source directory, so dirname()
that instead of needing the directory to be passed.

Needed because a follow-up commit will change when this is called, and the
source directory isn't trivially available at that point.
