And quiet noisy logging on normal write failures.
We can now stress test the thumbnail generation by setting
CAMLI_DISABLE_THUMB_CACHE=1 which will make all the thumbnails in the
browsers be unique, and not write them to cache on the server.
Then, when we're happy with the thumbnails, we just increment the
thumbnailVersion string and that busts all the browser- and
server-side caches.

Adds more tests to cover rotations with resize when used with
MaxWidth/MaxHeight, previously only ScaledWidth/ScaledHeight were
tested.
Improve tests to compare bounds when determining equality, otherwise
an image sized 0x0 is equal to all other images.
Sort test image filenames so test order is stable and obvious.
Keep more data in memory when indexing images upon receive. Some
largish CR2 files need more data or the EXIF parsing will fail.
Should address some or all of https://camlistore.org/issue/274

Makes the assumption that our old image logic was 'If the image is
huge (>2400px) shrink it to twice the target thumbnail size with
resample (which is quick) then box filter the image in half (which is
slow)'. There was a bug there that was causing large intermediary
images to be allocated when the source image was just the right size
and in portrait orientation (mainly trigger by photos from my Nexus 4).
Generalizes resize code to always resample to 2 times the thumbnail
size and then smooth down. Throws more pixels away faster.
Add downsizing routines that operate inplace. This greatly reduces
our peak memory usage when generating thumbnails.
Add version optimized for our particular resize case (halving);
providing a speed boost over the generalized versions.
Add tests and benchmarks comparing new resize to old.
Test for pkg/misc/resize can be run with --output=output_dir/ to see
the images generated by the old and new resize routines along with
mask of their differences.
Addresses some of the concerns in https://camlistore.org/issue/237

Running 'go run dev/envvardoc/envvardoc.go' now shows:
'All environment variables are documented'
I also took the liberty of cleaning-up our mishmash of logic for handling
boolean environment variables, and cleaned up a couple other spots that didn't
seem right.
This change adds docmentation for all variables starting with (CAM|DEV|AWS).
This leaves some variables still undocumented. If there are variables worth
documenting in the following list, maybe we should rename them to have a
CAM{LI} prefix for consistency's sake:

images: DecodeConfig to get the predicted width
and height after EXIF correction
search&index: add GetImageInfo and use it in search
to predict the thumbnail dimensions
http://camlistore.org/issue/115

This allows to know after a call to images.Decode if the image
was actually rotated or flipped.
Without knowing this, when making a thumbnail, it could happen
(if there was no rescaling required) that an image that needed
being rotated/flipped would not get rotated, because
useBytesUnchanged would still be true.
Change-Id: Ifc5e1e1f5a8543e6754102e3b3a685b736ae8673
This change implements rotation and flipping on images.
It can be done automatically, using the EXIF Orientation as a hint,
or optionally forced.
