Though currently jshn is more a one-shot data transformation tool and
won't leak much memory in its lifetime, people may use it as example
code, so do it right.

The cmake logic is wrong (E.G. PKG_CHECK_FOR_MODULES fails unless all
modules are found), and the legacy libjson.so name is also used by the other
libjson (http://sourceforge.net/projects/libjson/) which provides an
incompatible API, so just drop it.

Add a new helper function usock_port() which converts the given numeric port number
into a string using a private static buffer. This way a calling application can
conveniently use numeric port arguments without having to convert them before:
int fd = usock(USOCK_UDP, "example.org", usock_port(80));

When running the test case below the $key variable holds "foo bar" instead
of the expected "foo bar".

Quote the output of the "jshn -r" backtick expression to prevent the shell
from erroneously collapsing whitespace.

fd and timeout lua object has a __gc method in its metatable. After the object
is freed and the another new object use the same reference in __uloop_cb and
__uloop_fds, the new object will be freed by the old __gc of the old object
when garbag collecting.

When you call the fd_add, it will return an object with `delete` method.
So you can delete that event if you want.

Use uloop.fd_add like this:
local socket = require "socket"
udp = socket.udp()
uloop.fd_add(
udp, -- socket
function( -- callback function
ufd, -- socket object when register the fd
events -- uloop events. eg. uloop.ULOOP_READ .
)
local words, msg_or_ip, port_or_nil = ufd:receivefrom()
print('Recv UDP packet from '..msg_or_ip..':'..port_or_nil..' : '..words)
end,
uloop.ULOOP_READ -- event you want to listen
)
The `examples/uloop-example.lua` show an example of this work.
