Enhance io_submit() decoding
strace didn't decode important fields in the iocb passed to io_submit.
This patch changes the code to dump them all. Also it prefixes the fields
with names to make it easier to read.
* desc.c (iocb_cmd_lookup, print_common_flags): New functions.
(sys_io_submit): New iocb decoder.
Looks like this commit does not declare struct iocb,
with the following result:
...
gcc -DHAVE_CONFIG_H -I. -I./linux/i386 -I./linux -I./linux -Wall
-Wwrite-strings -g -O2 -MT desc.o -MD -MP -MF .deps/desc.Tpo -c -o desc.o desc.c
