Separate naming of functions that save complete files to disk
from functions that write data to streams.
|

Use fz_output in debug printing functions.
Use fz_output in pdfshow.
Use fz_output in fz_trace_device instead of stdout.
Use fz_output in pdf-write.c.
Rename fz_new_output_to_filename to fz_new_output_with_path.
Add seek and tell to fz_output.
Remove unused functions like fz_fprintf.
Fix typo in pdf_print_obj.

Previously, we had people calling image->get_pixmap directly. Now we
have them all call fz_image_get_pixmap, which will look for a cached
version in the store, and only call get_pixmap if required.
Previously fz_image_get_pixmap used to look for the cached version
in the store, and decode if not - hence the decoding code is now
extracted out into standard_image_get_pixmap.
This was the original intent of the code, it just somehow didn't end
up like that.
This nicely queues us up for being able to have fz_images that use
a different get_pixel implementation, such as that which will be
required for the gprf code.

If FZ_LARGEFILE is defined when building, MuPDF uses 64bit offsets
for files; this allows us to open streams larger than 2Gig.
The downsides to this are that:
* The xref entries are larger.
* All PDF ints are held as 64bit things rather than 32bit things
(to cope with /Prev entries, hint stream offsets etc).
* All file positions are stored as 64bits rather than 32.
The implementation works by detecting FZ_LARGEFILE. Some #ifdeffery
in fitz/system.h sets fz_off_t to either int or int64_t as appropriate,
and sets defines for fz_fopen, fz_fseek, fz_ftell etc as required.
These call the fseeko64 etc functions on linux (and so define
_LARGEFILE64_SOURCE) and the explicit 64bit functions on windows.

The new pdfclean sanitize functionality mean that mutool now
needs the data files, so maintaining the split that was designed to
keep data files out of mutool is no longer viable.

Purge several embedded contexts:
Remove embedded context in fz_output.
Remove embedded context in fz_stream.
Remove embedded context in fz_device.
Remove fz_rebind_stream (since it is no longer necessary).
Remove embedded context in svg_device.
Remove embedded context in XML parser.
Add ctx argument to fz_document functions.
Remove embedded context in fz_document.
Remove embedded context in pdf_document.
Remove embedded context in pdf_obj.
Make fz_page independent of fz_document in the interface.
We shouldn't need to pass the document to all functions handling a page.
If a page is tied to the source document, it's redundant; otherwise it's
just pointless.
Fix reference counting oddity in fz_new_image_from_pixmap.

Rename fz_close to fz_drop_stream.
Rename fz_close_archive to fz_drop_archive.
Rename fz_close_output to fz_drop_output.
Rename fz_free_* to fz_drop_*.
Rename pdf_free_* to pdf_drop_*.
Rename xps_free_* to xps_drop_*.

pdfextract_main by default iterates through all objects from number 0
to the size of the document's xref table. Object number 0 is however
always supposed to be free, so pdfextract consistently fails and shows
a slightly confusing warning. Object extraction should by default start
at object 1 in order to prevent this warning.

Thanks to Pengsu Cheng for pointing out the problem.

Remove the fz_context field to avoid the structure growing.
|
|
Match our naming conventions.
