revise loader demand hints
...
Add a check that header and load methods agree on the demand hint, and
make sure all loaders pass.
If they disagree, you can get bad performance in some cases, since the
pipeline can be built from the header dhint.

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.
