Bug fix.
When all the servers for a given server go away, the router deletes the
server class from its internal data structures. However that can happen
in the middle of a loop receiving successive messages from that server.
The old code would continue trying to read more messages from the
deleted server class, leading to a segfault.
The new code checks to see whether the server class still exists. If
not, it breaks out of the loop.

Instead of keeping all child processes in a single list, keep them in two
separate lists: one list of those which are currently servicing requests,
and another list of idle children. Move the children back and forth as
their status changes.
This change has three advantages:
1. When searching for an active child, there is a smaller list to search.
2. When doing a select() to identify children that have become available,
we can look for messages only from the active children, since the idle
ones won't write anything back to the parent. (Actually we could have
done this with a single list, but we didn't.)
3. Probably most important: since the idle list functions as a stack, we
assign the next request to the child that was most recently active, or was
most recently launched. That's the child that is most likely still to be
physically in memory. Formerly we assigned requests to children approximately
on a round-robin basis. As a result we assigned each new request to the
child that was most likely to be swapped out.
Also, in prefork_clear(): kill each child process individually. Sending a
SIGKILL to the entire process group kills the parent as well as the
children.

Changed the way pending requests are stored in an osrfAppSession.
Before, pending requests were stored in a so-called request_queue.
However it wasn't a queue at all, except in name. It was an
osrfList, i.e. an expandable pointer array used as a random
access container. Request ids were used as subscripts into the
array.
Since we don't reuse request ids (except in the theoretical case
of a wraparound), the array grew without limit. This unbounded
growth in the memory footprint could create problems for a
long-running busy process. It might have contributed to the
rumored instabililty of chopchop, our homegrown Jabber server.
Now, pending requests are stored in a hash table, where each
of 64 slots holds a doubly linked list. There should be no
effect on performance unless there are hundreds or thousands
of pending requests at once, in which case we would probably
get bogged down anyway.

Partial fix for launchpad bug 489294: OpenSRF seems to depend on explicit --prefix configure option
In the process of creating Perl and Python scripts using AC_SUBST(sysconfdir),
autoconf would generate variables like '${prefix}' if no explicit --prefix
option was passed to configure - and this would cause those scripts to fail
with syntax errors.
We can work around that, and so we shall. The bigger question is whether
creating scripts with hardcoded defaults results in problems when it comes
to creating system packages; according to http://www.gnu.org/software/hello/manual/autoconf/Installation-Directory-Variables.html
one should try to defer these changes to the Makefile so that the
destination directory can be specified at make or make install time,
instead.
At least this gets us working with no explicit configure options again.
Perhaps a packaging expert can help us out of this mire :)

Minor performance benefit: for one of the branches we avoid an

Implemented session_connected(), which had been declared in the header but never
defined.
Changed transport_client.c to use session_connected(), so that it wouldn't need to
see a declaration of jabber_machine.
Moved from transport_session.h to transport_session.c: several macros and the
declaration of jabber_machine, of which none are needed elsewhere.
Removed some comments from the header so that they won't override more complete
comments in the implementation file.
In session_connect(): inserted a return statement in order to bypass some
superfluous string comparisons.
Added the const qualifier to the return type of get_xml_attr(). We don't want to
be able to overwrite the text returned by the XML parser.
In endElementHandler(): look for "stream:error", to match the opening tag, instead
of "error:error".
Resest status_buffer along with the other buffers.
Introduced several minor performance tweaks.
Added more doxygen-style comments for documentation.

1. Replace the old JSON parser (jsonParseString()) with a newer, faster one
(jsonParse()).
2. Because the new JSON parser is strict about syntax errors that the old
parser would ignore, it was necessary to parse the srfsh command line more
intelligently. Otherwise it would be impossible to build a JSON string
internally with reliably correct syntax.
Hence: instead of using strtok() to break up the command line into tokens, we
now use a rudimentary recursive descent parser to isolate JSON strings as
distinct arguments, even if they contain embedded white space.
As a fairly benign side effect of these changes, the treatment of commas
in the command line is changing a bit. All parts of the command line
(not just JSON strings) may now be optionally separated by commas.
3. We now use an osrfStringArray to hold the results of parsing, rather
than a bare array of pointers.
4. The function formerly known as "parse_request" is now named "process_request",
because it does a lot more than just parsing.

Fix a bug in md5sum() (which only affected code compiled
with debugging turned on).
md5sum() builds an md5 message digest in a buffer. Originally
it used memset() to initialize the buffer with binary zeroes.
At some point the call to memset() was replaced with the
osrf_clearbuf() macro. When compiled in debugging mode,
osrf_clearbuf() fills the buffer with exclamation points;
otherwise it reverts to the original memset().
In this case the use of osrf_clearbuf is inappropriate, because
we use strcat() to build the message digest, two bytes at a
time. We don't need to use memset(), but the first byte needs
to be initialized to a nul byte so that strcat() will work as
intended. Hence:
1. Remove the call to osrf_clearbuf().
2. Put a nul byte at the beginning of the buffer.
Also, I made the buffer smaller. There's no reason for it
to be 256 bytes long.

Performance tweak to message handling.
In five locations in osrf_message.c, we were turning a jsonObject into
a JSON string, only to parse it again back into a jsonObject:
-- osrf_message_add_object_param()
-- osrfMessageToJSON() (two occurrences)
-- osrf_message_deserialize() (two occurrences)
That's silly.
This new version copies the original jsonObject directly, with no round
trip through a JSON string. We use jsonObjectDecodeClass() to do the
copy, in order to make sure that all class hints are decoded into
classnames.
(Until recently, jsonObjectDecodeClass() would remove classnames that were
already present. That's presumably the reason for the curious and
inefficient two-step procedure that we were using up till now.)
Also: In two locations (in osrf_message_add_object_param() and
osrf_message_add_param()) We used jsonParseString() to parse a
hard-coded "[]". I replaced those calls with equivalent (and faster)
calls to jsonNewObjectType( JSON_ARRAY );
Also: in osrf_message_set_result_content() I eliminated a pointless test
for nullity of the json_string variable. An earlier test already
guarantees that json_string is not NULL.

At present this change will have no effect. Apart from a

we pass a freshly parsed jsonObject that can't possibly

Enhance the performance of the recursive descent JSON parser,
mainly the jsonParse() function.
1. The old version would create a jsonObject and then copy it, with
possible modifications, via a call to jsonObjectDecodeClass(), in
order to decode class hints into the classname member. Finally, it
would throw away the original jsonObject.
The copying operation is expensive, and the new version eliminates
it. When decoding is desired (which is nearly always), execution
passes through a parallel version of the get_hash() function, which
does the decoding on the fly.
In my benchmarking, the new version reduces the parsing time by
around 35 - 45 percent. It is now at least twice as fast as the
older jsonParseString() function, which uses a finite state
machine instead of recursive descent.
2. In get_number(): instead of allocating and destroying a
temporary growing_buffer, use the one available in the
Parser structure.
3. In osrf_json.h: Applied some pedantic corrections to the
doxygen comments for the old parser.
--------
In all cases tested, the new version produces results identical
to those of the old version. The results are also identical to
those of the older parser, apart from error detection.
