John Cupitt 01eed391ab add sync locks to vips_sink()
vips_sink() used to just fire off threads willy nilly -- this could
cause problems with sequential images if a worker fell too far behind
the pack

copy over the area locking mechanism from vips_sink_memory(): new
threads are now stalled if an old thread has not finished

John Cupitt 24c07cfde2 revert an accidental ABI break
the new window manager code in 8.6.1 changed the prototype of an internal
function which was visible in the public API

and adds a stub for the old prototype

John Cupitt 653e99ea82 don't build enumtypes so often

now we always replace it, so (hopefully) perl is no longer a
compile-time dependency

John Cupitt 47a763209a 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 old 'disc' flag to open defaulted TRUE and disabled read via disc if you

read via memory if set TRUE

John Cupitt 7b64246af2 fix a couple of issues with huge profiles
The base64 encode limit was 1MB, but some huge profiles can get over
that, so it's now 10MB.

transform_save_string_blob() was incorrectly setting a refstring not a
blob as an error fallback, potentially leaving a dangling pointer.

continue
* if the file format library reports an error and fail is set, we log it
and fail

are being tracked

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
