James R. Barlow 5ba56adb53 Fix page rotation issue (again) 
Commit 1327ab3 introduced a fix for a regression, which was reported
in #581, #634. It appears that the actual cause of this issue was
default parameters to rasterize_pdf_page in pluggy not working as
expected, causing a default rotation=0 even when a rotation was needed.
As such the OCR image was generated with the wrong orientation,
causing the initial regression and fix in commit 1327ab3.

Now that the real problem is identified, it's apparent that the logic
prior to 1327ab3 was found and we can revert to 1327ab3 since it fixes
all known cases including #658.

This reverts 1327ab3 except for retaining improves to rotation output.

James R. Barlow d1e0c81eda Ensure worker_pdf is closed after gathering info in a thread 
This is hacky, uses global state, but it does improve the situation for now.

James R. Barlow 10c8e4f8b4 Only create debug.log when running from command line 
When used as a library ocrmypdf shouldn't make policy decisions, like where to
put a log file. Unsurprisingly, creating it causes problems for library users
because we deleted the temporary folder which held the log file and made no
effort to move it to a new location.

Also update the documentation to better described how an application should
handle this.

Closes #657

James R. Barlow b93cf51c0f Disable pikepdf mmap 
Infrequently we can reproduce this error:

terminating with uncaught exception of type std::runtime_error: pybind11_object_dealloc(): Tried to deallocate unregistered instance!

The error is probably related to pybind11 issue #2252 and a bunch of
other related issues. Until that is resolved in pybind11 and pikepdf
we will disable the pikepdf mmap interface.
