Fix up vips_text()
...
Fixes two issues:
1. vips_text() in autofit mode could set the wrong DPI, since it set the
DPI in its own copy of the variable, but did not do a final update on
the DPI setting that FT uses for rendering.
2. vips_text() in autofit mode allocated a new context each time, rather
than reusing the context for that call. This caused a small memory leak.

strict round down on jpeg shrink

Before, they could make B_W for one-band output. This caused problems
with (for example) two black image bandjoined: the second band then
looked like an alpha to hasalpha() and enabled premultiply/unpremultiply
for operations like affine.
Now, it's always MULTIBAND. This is the generic multiband image type, so
you don't get any unexpected alpha handling.

icc_import attaches the input profile if used
...
icc_import can take a fallback input profile in case the embedded one is
broken or missing. If we use the fallback profile, this change attaches
it to the output image.
This means that icc_import will always output an image with the icc
profile that was used to import it. This helps to make the behaviour of
`thumbnail` more consistent.

fix a crash with delayed load
...
If a delayed load failed, it could leave the pipeline only half-set up.
Sebsequent threads could then segv.
Set a load-has-failed flag and test before generate.

improve rounding in convi intize
...
We were rounding up with ceil() when intize-ing convolution masks.
However, the vector path has a true range of (1.0, -1.0], so a mask with
1.0 as the max (for example) was actually triggering the overflow detector
and falling back to the C path.
Round up with ceil(x + 1) instead, so 1.0 (for example) will be mapped
to 0.5 and won't overflow.

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
