347aafa6d7 Fix some build warnings when building with musl 2020-11-18 14:45:11 -08:00

b5e75ff7d1 fix build with gcc 10 
Define setjmp_buffer as static to avoid the following build failure with
gcc 10 (which defaults to -fno-common):

/home/buildroot/autobuild/instance-1/output-1/host/lib/gcc/arm-buildroot-linux-gnueabihf/10.2.0/../../../../arm-buildroot-linux-gnueabihf/bin/ld: image_utils.o:(.bss+0x0): multiple definition of `setjmp_buffer'; metadata.o:(.bss+0x0): first defined here
collect2: error: ld returned 1 exit status

46c692fc59 metadata: Reduce stack usage in nfo parsing 
64KB is a bit much for a stack buffer.  Use dynamic allocation instead.

c29a9cf52b image: Support rotation of monochrome JPEGs. 
Extends the existing 90°-increment rotation support
(i.e. /Resized/ID?rotation=DEG) to monochrome JPEGs.

SF Patch #135 (Thanks R.L. Horn).

f18c3cee6f image: Improve resize quality at the edges. 
get_pix() returns opaque black pixels for out-of-bounds coordinates, resulting
in spurious averages at the edges. The attached patch appears to fix the
problem, at least for the floating-point resizers.

From SF user R.L. Horn.
