I started working on a new command line utility that used this shared
code. I wanted the ability to pass some data from common
initialization code to all of the commands. You can find a similar
pattern in ovs-vsctl.
This patch updates the command handler to take a new struct,
ovs_cmdl_context, instead of argc and argv directly. It includes argc
and argv, but also includes an opaque type (void *), where the user of
this API can attach its custom data it wants passed along to command
handlers.
This patch affected the ovstest sub-programs, as well. The patch
includes a bit of an odd hack to OVSTEST_REGISTER() to avoid making
the main() function of the sub-programs take a ovs_cmdl_context.
The test main() functions still receive argc and argv directly, as
that seems more natural. The test-subprograms themselves are able to
make use of a context internally, though.
