Subject: [PATCH] udp: Avoid including netdb.h
netdb.h pulls in a large chain of include files:
rpc/netdb.h
rpc/types.h
rpc/types.h re-defines TRUE/FALSE and does it in this way:
#ifndef FALSE
# define FALSE (0)
#endif
#ifndef TRUE
# define TRUE (1)
#endif
And this later causes build problems that appear in this way:
mipsel-linux-gnu-gcc -Wall -DVER=1.8 -D_GNU_SOURCE -DHAVE_CLOCK_ADJTIME
-DHAVE_POSIX_SPAWN -DHAVE_ONESTEP_SYNC -Os -pipe -mno-branch-likely
-mips32r2 -mtune=24kc -fno-caller-saves -Wno-unused-result
-D_FORTIFY_SOURCE=1 -Wl,-z,now -Wl,-z,relro
-I/home/florian/dev/openwrt/trunk/staging_dir/target-mipsel-unknown-linux-gnu_glibc/usr/include
-I/home/florian/dev/openwrt/trunk/staging_dir/target-mipsel-unknown-linux-gnu_glibc/include
-I/home/florian/dev/toolchains/stbgcc-4.8-1.5/usr/include
-I/home/florian/dev/toolchains/stbgcc-4.8-1.5/include
-DHAVE_CLOCK_ADJTIME -DHAVE_POSIX_SPAWN -DHAVE_ONESTEP_SYNC -c -o
udp.o udp.c

<builtin>: recipe for target 'udp.o' failed
Upon inspection, it does not appear that netdb.h is providing any useful
definition or declaration, so let's just remove its inclusion.
