[ptxdist] [PATCH v2 4/7] poppler: version bump 0.18.0 -> 0.59.0

[Roland Hieber <r.hieber@pengutronix.de>]

This is quite a version bump, spanning six years of poppler development.
Upstream now provides data for rendering cyrillic languages in the
package poppler-data, but this dependency is only detected at compile
time, so make sure the build order is right.

Some applications require the old xpdf headers, the CPP wrapper or CMYK
support, so make these configure options selectable. Same for the Splash
backend, which can now also be built with single precision or
fixed-point arithmetic. PNG and JPEG support is no longer broken,
poppler now also includes an internal DCT decoder. The GTK dependency
has been dropped (or was it even necessary in the first place?)

Don't wonder about --disable-relocatable, it only applies to Windows.

poppler allows using zlib to uncompress flate streams, but with the
warning that this is "not totally safe", so I disabled it.

Additionally, poppler could benefit from packaging libopenjpeg and
libtiff in ptxdist for parsing embedded JPEG2000 or TIFF in PDFs.
Likewise, libnss could be packaged for PDF signature support. Also
there is the option to build a Qt5 wrapper, but I don't have a good way
to test this, so it is currently disabled.

Notes:
    changes in v1 -> v2:
     - version bump to 0.59.0, includes our 0.57.0 patches from v1
     - bring back old vim modeline
     - simplify single-precision/fixed-point logic
