Error handling now:
* gives name of mutex when fails.
* if clock_gettime() fails, this is fatal for CLOCK_REALTIME
and CLOCK_MONOTONIC (as before) but not for any other
clock (new behaviour).
* log errors (and other anomalies) in pthread_getcpuclockid(),
but do not abort.
Remove a couple of warnings about variable "format" values for
printf-like functions.
Fix bug in new vtysh/extract.pl -- change mechanics of extracting
CMD_INSTALL_TABLE entries, so that deals better with #if etc
between entries.

gcc 4.6.1 picked up a couple of (spurious) "may be used unitialised"
variables -- fixed.
For reasons unknown FreeBSD unistd.h declares
_POSIX_THREAD_SAFE_FUNCTIONS as -1... which tripped a CONFIRM().
_POSIX_SPIN_LOCKS is declared 200112, and according to POSIX-2004
_POSIX_SPIN_LOCKS => _POSIX_THREAD_SAFE_FUNCTIONS -- so it is a
bit of a surprise (though the statement in POSIX is in the context
of support for "Advanced Realtime Threads", which includes
_POSIX_SPIN_LOCKS)... Recast to warn instead of generate
compilation error.
Fixed test-prefix.c to work with uint8_t sa_family_t !

Added -W command line argument to bgpd to start watch-dog:
-W99[,[+]path]
where: 99 is the watch-dog interval, eg. 2 or 5
path is file that watch-dog writes to -- default is
stderr.
if '+' is given, will append to the file.
Watch-Dog looks out for:
* not being woken up when expected.
* CLOCK_REALTIME and CLOCK_MONOTONIC not advancing together.
* pthreads stalling.
* mutexes being locked for long periods.
* CPU consumption by each pthread in each watch-dog interval.
If pthreads are locking up or going into a flat spin, the
Watch-Dog should spot it.
Pro tem: outputs pthread properties to stderr at start-up.

-Wunused-but-set-variable throws up a number of errors, this patch
removes some of thos in bgpd, lib and zebra.
Fix crash in vty when using ">*" /dev/null output pipe.
Work in Progress (WIP):
1) adding "Watch-Dog" pthread to keep an eye on all other pthreads
and state of mutexes etc.
2) creation of Integrated Configuration in vtysh.

* bgp_peer_index
replace unused bgp_peer_index_reset() by bgp_peer_index_finish()
and call same at bgp shut-down.
discard unused bgp_peer_index_mutex_free() and replace
bgp_peer_index_mutex_init() by bgp_peer_index_init_r().
* lib/command.c and command_parse.c
add cmd_parser_finish() to discard store of "words" and arrange to
call same in cmd_table_terminate().
* reset vector of files in qps_selection_ream(), so that frees the
vector body -- which it should have been doing !
* add mem_mt_show_stderr() for debug (for all the use it may be).
* fix qpt_mutex_destroy(), qpt_cond_destroy() and qpt_spin_destroy()
so that if fail when !qpthreads_active will log the error (and not
crash). Sweeps issues under the carpet, but does not hide same.

* fix stream_put() to accept NULL src (again).
* changed how vty terminal reports time-out and end-of-file,
and made --more-- show the same as ordinary cli.
* tighten on or two stream functions, to cope if for some
reason the getp > endp or endp > size.
* update documentation in vio_lines.c
* fixed (potential) bug which would have tripped up --more--
if were to be required while outputting notification for a
cancel operation.
* as a new command loop is set up, make sure all start in
vst_cmd_running_executing, so that output will be dispatched.
* fix uty_std_out_push() and uty_vtysh_out_push to take notice
of vst_cmd_running and vst_cmd_executing and change to
vst_cmd_complete as required.
* fix handling of hold_mark in VOUT_TERM obuf an line control.
* fix various state related issues for vtysh server and the
vtysh itself.
* when vtysh connects to a daemon, the daemon responds with
its name and version number.
TBD: the vtysh to check that version is as expected !
* clarified handling of errors in vtysh... distinguishing
errors reported by the client daemon, and errors in the
mechanics of talking to the client daemon.

NB: this is a partial interim version -- NOT for production.
Reinstate vtysh. In bgpd: cope better with generating oversize messages.
The "pipework" branch is no more. There is now "euro_ix" and "euro_ix_b",
where 'b' stands for 'bleedin'. The "pipework" is currently in 'bleedin'.
Version updated to: 0.99.18ex20b
Major changes in this commit:
* modified bgpd to avoid crashing if an oversize message is created.
At present, any oversize messages are simply discarded. This may be a
mistake... since it is possible that some routes that should have been
withdrawn are not. TBA.
The stream lib facilities have been overhauled to may this easier.
* restoring vtysh.
At present the vtysh is thought to work, except that it does not
currently create integrated configuration files.
For the time being, *only* the following compile:
lib, bgpd, zebra, vtysh, tests
All other daemons will fail to compile, and must be disabled.

Version advanced to 0.99.18ex19p.
Fixed occasional failure to immediately display prompt after
previous command output was abandonned by ^C, particularly with
"--more--".
Completely removed the "~" temporary prompt, and simplified some
logic.
Added indication of pthread running to "show version".

Improve error handling for all new pipework inputs and outputs.
Change behaviour of ^C from VTY Terminal, so that will interrupt
output and terminate all running pipes -- including running
shell commands.
In pipe commands, recognise "~/..." and "~user/..." home directory
forms.
Changed "~/" to mean the usual home for the current user. "~~/"
now means the configuration file directory.
Introduced "shdir DIR" command to show what is (currently) what.
Changed "<|" so that if the command has a path, it is expanded
using Quagga's rules (including "~~/" and "~./") and the
"here" directory is set to that path.
Fixed collection of stderr output from all pipes so that is
separate from stdout output, and is always sent to the base
output (eg VTY Terminal).
Increase amount of information about the heap that "show mem"
shows -- particularly if the "memory_tracker" is enabled.
Tested and applied resulting fixes.

Tidy up signalling of "ready" to command loop, and checking of
appropriate state to close written configuration file.
