d251b37d92 add vips_argument_get_id() 
We had a global we incremented to allocate property ids, but of course that
won't work with DLLs. Instead, add vips_argument_get_id() and call that to
allocate new prop ids.

1a95b2df89 fix tga header read 
When you ping() an image with imagemagick to get the header, some format
loaders (eg. TGA) don't set all the fields. In this case,
image->colormap was not set and that made GetImageChannelDepth() crash.

Work around this, at least in this case, by allocating a colourmap
ourselves if none is set.

b085908558 remove vips7 stuff from API 
You must now include vips7 support explicitly with

	#include <vips/vips7compat.h>

in your code just after including `vips.h`.

The old vips7 names, such as `Rect`, were starting to cause problems
with other packages like opencv.

265fb2a825 improve colourspace guessing in icc 
icc_transform does a better job of guessing the colourspace of an image -- if
the colourspace has not been set (generic multiband), it'll look at the
image bands instead and guess from that

Fixed deadlock in vips_cache_drop_all if vips__cache_dump is true

80a0a24cfa Fixed deadlock in vips_cache_drop_all if vips__cache_dump is true 
Both vips_cache_drop_all and vips_cache_print acquire vips_cache_lock
on entry, but vips_cache_drop_all calls vips_cache_print internally if
vips__cache_dump is true, leading to a deadlock situation.
This commit solves the issue using one further level of indirection
and a new vips_cache_print_nolock function.

d3439f4d49 Fix wrong value for VIPS_FOREIGN_PNG_FILTER_ALL 
The value is derived by oring all the filter flags:

    0x08 | 0x10 | 0x20 | 0x40 | 0x80 == 0xf8

The value was also checked against PNG_ALL_FILTERS in png.h.
