fix a crash with heavy use of draw

we were leaving a few bits of the original image around after
vips_image_copy_memory(), including the progress signal ... if earlier images

we were only replacing enumtypes if it had changed, but this meant that

hide warnings if VIPS_WARNING is defined
...
If VIPS_WARNING is defined, suppress all warning messages from vips by
installing a null log handler.
Libraries should not call g_log_set_handler(), it is supposed to be for
the application layer, but this can be awkward to set up if you are using
libvips from something like Ruby.
This env var hack is a workaround.

The base64 encode limit was 1MB, but some huge profiles can get over

add CLAHE
...
vips_hist_local() has a new param, max_slope, which sets the maximum
amount that the local contrast can be boosted by -- CLAHE
see https://github.com/jcupitt/libvips/issues/268
also fix a couple of small range problems
- scale by 255, not 256, to avoid an overflow
- cum hist includes the current value, so sum to <= target, not < target

upsize with something other than nearest
...
vips_resize() uses to just use nearest when upsizing, following standard
practice in repro. This is often unfortunate for image processing, where
small nearest upsizes will produce obvious aliasing.
It now picks a VipsInterpolate which corresponds (roughly) to the
selected VipsKernel and uses that with affine for any upsizing.

better vips_resize() for cubic/linear/nearest
...
vips_resize() used to do most of a downsize with vips_shrink() and the
final 200 - 300% with vips_reduce(). This was correct for lanczos2/3,
but not right for linear/cubic, which need more shrink and less
reduce to avoid aliasing.
This patch makes vips_resize() leave the final 100 - 200% to
vips_reduce() for linear/cubic, and leave everything to reduce for
nearest.

vips_image_write() only refs input when it has to

free pixel buffers on image close
...
We were freeing pixel buffers on thread exit. This was convenient, but
meant that main thread buffers were not freed until program exit. As a
result, long-running programs which created main thread buffers would
slowly fill the operation cache with useless junk, forcing everything else out.
This change also frees pixel buffers on image close. This makes the
cache work much better in long-running programs, and can substantially
reduce memory use.

free main-thread pixel buffers
...
threads keep pixel buffers in thread-private storage, and free these
buffers on thread exit ... this means buffers created by the main thread will
only be freed on program exit!
if your program creates any main-thread buffers, these buffers will
eventually fill the operation cache and force everything else out,
making the cache useless
this patch explicitly frees main-thread pixel buffers on image close

restore bandfmt after unpremultiply in thumbnail
...
vips_unpremultiply() always outputs float. If you save the output of
vipsthumbnail to a format that supports float files, like tiff, it won't
ever get cast back to the source format.
Example:
$ vipsheader Opera-icon-high-res.png
Opera-icon-high-res.png: 3056x3325 uchar, 4 bands, srgb, pngload
$ vipsthumbnail Opera-icon-high-res.png -o x.tif
$ vipsheader x.tif
x.tif: 117x128 float, 4 bands, scrgb, tiffload
This change makes it note and restore BandFmt aropund pre/unpremultiply.
