6130c10567 Use NO_WCAST_ALIGN for usr.bin/hastctl and usr.bin/hastd; the alignment
warnings in sbin/hastd/lzf.c are only emitted for i386 and amd64, and
there they can be safely ignored.

e2eabb44d7 The proto API is a general purpose API, so don't use 'hast' in structures or
function names. It can now be used outside of HAST.

9e5bdc9d83 - Turn on printf extentions.
- Load support for %T for pritning time.
- Add support for %N for printing number in human readable form.
- Add support for %S for printing sockaddr structure (currently only AF_INET
  family is supported, as this is all we need in HAST).
- Disable gcc compile-time format checking as this will no longer work.

8cd3d45ad9 Allow to compress on-the-wire data using two algorithms:
- HOLE - it simply turns all-zero blocks into few bytes header;
	it is extremely fast, so it is turned on by default;
	it is mostly intended to speed up initial synchronization
	where we expect many zeros;
- LZF - very fast algorithm by Marc Alexander Lehmann, which shows
	very decent compression ratio and has BSD license.

5bdff860e7 Because it is very hard to make fork(2) from threaded process safe (we are
limited to async-signal safe functions in the child process), move all hooks
execution to the main (non-threaded) process.

Do it by maintaining connection (socketpair) between child and parent
and sending events from the child to parent, so it can execute the hook.

This is step in right direction for others reasons too. For example there is
one less problem to drop privs in worker processes.

7729e3ba40 Remove redundant WARNS?=6 overrides and inherit the WARNS setting from
the toplevel directory.

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.
