The 'log2()' and 'log2f()' functions have been added in FreeBSD's libc
version 9.0.0, but they are missing in version 8.2.0, which is used in
Genode. This patch provides preliminary implementations of these
functions until the Genode libc gets updated to version 9.0.0 or above.
Fixes#143.
This version of the library was hardwired to the former USB storage
driver supplied with DDE Linux. This driver is no more. The ffat.mk lib
is superseded by the libc_ffat plugin anyway. This plugin uses Genode's
block session interface instead of co-locating the block driver with the
application.
MuPDF is a fast and versatile PDF rendering library with only a few
dependencies. It depends on openjpeg (JPEG2000 codec) and jbig2dec (b/w
image compression library). Therefore, this patch comprises the ports of
these libraries as well. All libraries compile well in the Genode build
system but are not tested yet.
Removed dummy implementation of '_ioctl'. This function is called
internally within the libc, i.e., by 'tcgetattr'. For running
libreadline in Noux, we need to hook into those ioctl operations via
the libc plugin interface.
