005f438bf5 - Use pjdlog_exitx() to log errors and exit instead of errx(). 
- Use 'unable to' (instead of 'cannot') consistently.

524840d8d0 Problem with assertion is that it logs on stderr. Add two macros: 
PJDLOG_ASSERT() and PJDLOG_VERIFY() that will check the given condition
and log the problem where appropriate. The difference between those
two is that PJDLOG_VERIFY() always work and PJDLOG_ASSERT() can be
turned off by defining NDEBUG.

declare it is the default and be placed at the end of the queue so it is
checked last.

9fab3c1b94 Remove macros that are not really needed. The idea was to have them in case 
we grow more descriptors, but I'll reconsider readding them once we get there.

Passing (a = b) expression to FD_ISSET() is bad idea, as FD_ISSET() evaluates
its argument twice.

d92714eea8 Default connection timeout is way too long. To make it shorter we have to 
make socket non-blocking, connect() and if we get EINPROGRESS, we have to
wait using select(). Very complex, but I know no other way to define
connection timeout for a given socket.

secondary, which died between send(2) and recv(2). Do it by adding timeout
to recv(2) for primary incoming and outgoing sockets and secondary outgoing
socket.

This does not change any WARNS level and survives a make universe.

32115b105a Please welcome HAST - Highly Avalable Storage. 
HAST allows to transparently store data on two physically separated machines
connected over the TCP/IP network. HAST works in Primary-Secondary
(Master-Backup, Master-Slave) configuration, which means that only one of the
cluster nodes can be active at any given time. Only Primary node is able to
handle I/O requests to HAST-managed devices. Currently HAST is limited to two
cluster nodes in total.

HAST operates on block level - it provides disk-like devices in /dev/hast/
directory for use by file systems and/or applications. Working on block level
makes it transparent for file systems and applications. There in no difference
between using HAST-provided device and raw disk, partition, etc. All of them
are just regular GEOM providers in FreeBSD.

For more information please consult hastd(8), hastctl(8) and hast.conf(5)
manual pages, as well as http://wiki.FreeBSD.org/HAST.
