James R. Barlow eb5200d26a Change most tests to use ocrmypdf API instead of subprocess 
The main benefit of this is code coverage gains can actually follow it.
Also removes most ugly os.environ hacks.

James R. Barlow b27b92fbf3 optimize: on aggressive settings try JPG to PNG transcoding 
If the color count of an image is low such as when black and white
documents are scanned in color, PNG with lossy quantization may
produce a superior encoding to JPEG. This is expensive to test however.

James R. Barlow 67a405c6b7 Move install-time external program checks out of setup.py 
We did runtime tests for several of them anyway, and it's better to do
at runtime since config may change after installation.

James R. Barlow 19e35db2b7 Fix issue when weave handoff occurs with no OCR font present 
If using --tesseract-timeout 0 and any image processing on a file with
more than 100 pages, the weave handoff will occur. Ensure this
works correctly even if no Glyphless font is present.

Closes #347

James R. Barlow 03ab5a8ee2 If --tesseract-timeout 0, say nothing when we time out

James R. Barlow 6f554c6ae8 tesseract: account for behavior changes when params are missing 
Tesseract 4.0-rc1 now accepts invalid parameters in config and
won't return an error anymore. We prefer to raise an error if this
occurs.

James R. Barlow bb50501369 ghostscript: never use autorotatepages 
It looks like from the gs manual that this parameter is only respected for
vector devices so it never had any effect, but to stay on the safe side,
which it off.

James R. Barlow 47885f4230 Remove initial qpdf.repair 
Since pikepdf is doing the work the initial repair takes time and gives
little benefit.

It turns out to not be worthwhile to
save the results of PdfInfo parsing,
since the time to save this seems to exceed the costs of recalculating
it since the "weave" code. At least
for small files.

James R. Barlow 94150f414a Remove qpdf.merge 
We no longer need to merge pages this way. Much of the functionality
was there to implement page splitting without hitting ulimit which
will be fixed in qpdf > 8.0.2. The tests were expensive to run.

Also remove pytest-timeout since it breaks the Linux build.
