Don't depend on stdio.h for our own I/O functions.

Fits with the rest of the code.

Move the definition of the structure contents into new fitz-imp.h
file. Make all code outside of fitz access the buffer through the
defined API.
Add a convenience API for people that want to get buffers as
null terminated C strings.

All seen in MSVC, mostly in 64bit builds.

Previously it was inherently tied to zip archives and directories.
Now these are separated out into distinct subclasses. This prepares
for support for further archive formats.
|
|
The size listed in the central directory can be used to allocate an
output buffer and inflate can be told to not write more than this
number of bytes. The listed size cannot be assumed to be the size
of the output data however as the zip file may be corrupted. Instead
the size of the output data must be given by inflate and must be
less than or equal to the listed size.
The same reasoning goes for uncompressed entries and simply reading
the uncompressed data from the archive file (which may terminate
early).
Fixes indeterminism broken_png_image.xps.

This silences the many warnings we get when building for x64
in windows.
This does not address any of the warnings we get in thirdparty
libraries - in particular harfbuzz. These look (at a quick
glance) harmless though.

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.

It's a C99ism.

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.

fz_open_file does not return NULL on failure -- it throws an exception!

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_*.

Commit 5add23c7233c3f34fdfa6387873b1d3bdb93e1d6 and commit
2f4cdd4fd0580e3121773e89a7c6e7a9e1ffa54b introduced three memory leaks
which only appear in error cases:
* unzip.c leaks if a ZIP archive uses a compression method other than
store or Deflate
* xps-zip.c leaks if fz_open_archive_with_stream throws for broken
ZIP archives
* xps-zip.c leaks also if a piece of a split file is missing
