Different distributions have different names for the lua 5.1 package.
Use cmake's built in pkg-config support to search for the first one,
rather than running it explicitly and searching for a single version.

Race is possible in ulog_kmsg(): if no /dev/kmsg exists
(e.g. while /dev gets re-mounted) regular file created instead.
>From this point system goes without kernel logger:
special character file can't be created anymore, all clients keep
overwriting single message in regular file.
To avoid this we open file in "r+" mode which doesn't create
file if it's not found.

The default uloop error handling is to delete the fd. Continue to do
that, but also set the write_error flag and notify the user.

Add ability to skip building the examples. The default value is ON to follow
the original cmake behavior.

User's s->notify_read is called in ustream_fill_read(). If
s->read_blocked is set there, then stop reading more.

No functional change.
- Reuse existing NULL check on buf.
- Add some comments for ease of reading the code.

Use PKG_SEARCH_MODULE() to detect json-c library,
otherwise the search fails, if both json-c and json
are not present in pkg-config database.

The ulog api is intended to be used by procd, fstools, ubox etc. to provide
a generic logging api for early boot messages and automatic switching between
syslog / kmsg / stdout depending on the way the process is executed.

Most app don't want to crash because of unhandled SIGPIPE. It could
happen is such trivial situations like writing to socket.

It turns out that mach_absolute_time() is not monotonic at all. While
at it, convert the CLOCK_REALTIME implementation to using
clock_get_time() as well.

It can be used to fill caller-specified buffer with data already in
ustream read buffer. Useful in the following use pattern.
int available = ustream_pending_data(s, false);
if (available >= sizeof(struct msghdr)) {
struct msghdr h;
ustream_read(s, &h, sizeof(h));
}

Otherwise some flags like USOCK_NONBLOCK wouldn't work as expected
(O_NONBLOCK affects connect behavior).

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.
