4ef825014d extract is sequential again

b183d32b15 use a hash table for tilecache
now we can have large numbers of tiles, use a hash table for tile lookup

65f679c7ac add a line cache
add vips_linecache() ... like tilecache, but caches scanlines and sizes
dynamically with request size

1abac4018a better enum arg error message
you now get something like:

$ vips tiffsave k2.jpg x.tif --compression poop
tiffsave: enum 'VipsForeignTiffCompression' has no member 'poop', should be one of: none, jpeg, deflate, packbits, ccittfax4, lzw

463058c149 note and use res unit on jpg load/save
previously, jpeg save always used pixels/inch and jpeg load converted to
vips pixels/mm

now on jpg load the image's res unit is recorded in
VIPS_META_RESOLUTION_UNIT, and on jpg save the res unit is set from
VIPS_META_RESOLUTION_UNIT (or defaults to inches).

you can now copy a cm-preferring tiff to a jpg and the unit is preserved

8214d15982 more improvements to dzsave
now writes x_files and x.dzi, as per spec (thanks Benjamin)

deprecate tile_width and tile_height, just have tile_size now

a9c7a36670 be more cautious enabling tiff ycbcr
we were turning on ycbcr for all jpeg tiffs and relying on the jpeg
compressor to only use it when possible ... now just turn on ycbcr for
8-bit RGB images

a71fe51d2d support "rs" mode in im_open()

73f8263286 sequential can now skip ahead
vips_sequential() no longer bans all non-seq access, it just bans
rewinding --- if you ask for something some way ahead, it reads and
throws away pixels

this means VipsExtract and VipsInsert can now be seq: they will read and
throw away any stuff they don't need

25ad2b7a53 turn off seq mode in vips7
the new sequential mode readers for tiff/jpg/png were not working well
from the vips7 command-line: they either decompressed twice, or handed
over a sequential mode image

it should now work as well as it did pre-seq.

643dc28950 turn on seq mode automatically in cli
cli operations turn on seq mode automatically when they can

vips_operation_get_flags() added: lets you attach a set of flags to an
operation

flags for now are "nocache" (replacing the old nocache system) and "seqential"

if vips_object_set_argument_from_string() from string sees "seq" flag on the
object for which it is setting the arg, it enables sequential mode

all operations which can run sequentially have been tagged

the operation printer knows about flags and can display them

8582e40307 improve use from many threads
lock around the operation cache and the upstrea/downstream link system
so vips works when used from many threads: you can now create an image
in one thread and process it in another

daac11b01c add "minimise" signal
on end of an image loop, send a "minimise" signal down the pipeline

tilecache listens for this signal on its output and drops the cache
