move tiff decompress outside lock (#2969) 
* move tiff decompress outside lock

Most time in TIFF read is spent in decompression. If we move this
outside the lock, we can get a useful speedup.

This commit adds the machinery to move the lock to before decompress, so
jp2k decompression is now threaded.

Before:

```
$ vips copy wtc.jpg x.tif[tile,compression=jp2k]
$ time vips avg x.tif
117.249845
real	0m15.085s
user	0m16.155s
sys	0m0.109s
```

After:

```
$ time vips avg x.tif
117.249845
real	0m1.207s
user	0m18.384s
sys	0m0.369s
```

* start moving jpg decode outside the lock

* move jpeg decompress outside the lock

seems to work

* add some more tile size checks

double-check jpeg tile size before decode

* fix tiffload demand hinting

We were not setting the hint correctly in header load, and we were not
hinting smalltile for tiled TIFFs.

Improve symbol visibility (#2688) 
* Improve symbol visibility

* Decorate required internal symbols with VIPS_API

* Remove a couple of stray header decls

* Incorporate review comment

- Ensure symbol visibility is also set on static libraries.
- Prefer to use `cc.has_function_attribute('visibility:hidden')`.

* Don't export internal deprecated symbols

* Move deprecated symbols to vips7compat.h

* `IM_FORMAT_H` -> `VIPS_FORMAT_H`

* Move `vips_window_ref` compat stub to `vips7compat.c`

* Disable deprecation warnings internally

* `vips_image_get_kill` -> `vips_image_iskilled`

* Ensure API compatibility

* Add missing include directives

* Move `vips__init` decl to vips7compat

* Move `vips__get_sizeof_vipsobject` to vips7compat

* Fix introspection build

* Fix 2 introspection warnings

* Ensure compatibility with vipsdisp

John Cupitt 5117c1a980 remove mode_t from headers 
it seems to fail with MSVC.

int works fine, and is what g_open() uses.

Kleis Auke Wolthuizen 9246094033 Fix function pointer cast issues 
It is undefined behavior in C and C++ to cast a function pointer
to another type and call it that way. This does work in most native
platforms, however, despite it being UB, but in WASM it can fail.

Kleis Auke Wolthuizen 6fc2015783 Remove use of varargs in vips_*_open 
This matches the declaration of g_open and helps tools (such as ASan) when
running on non-native platforms.

John Cupitt 4b2c8587b2 vips_malloc() size tracking 
vips_malloc() now tracks allocation size and can report total mem use.
It seems to trigger quite a few nip2 bugs though, I guess we are
g_free()ing the result in places (or vice versa).
