Extended the JSON_INIT_CLEAR macro to avoid segfaults.
Scenario: converting a JSON_BOOL, with a value of true, to a JSON_HASH or
JSON_ARRAY. The true value (in a union with an osrfHash* and an osrfList*)
was being interpreted as a non_NULL pointer and deferenced. Oops.
With this change, we clear the boolean value (by nullifying one of the
unioned pointers) whenever changing from a JSON_BOOL to anything else.

Performance tweak to jsonIterator.
Instead of storing a malloc'd copy of the key of a JSON_HASH entry,
just store a const pointer to the key string stored in the
internal osrfHash. That way we don't have to do a malloc and
free every time we bump the iterator.
This change also requires the addition of a couple of const qualifiers
in the client code.
This is a performance tweak to the osrfHashGet function, a widely
used utility function.
The old version accepted a variable number of arguments: a pointer
to an osrfHash, a string optionally containing printf-style
format specifiers, and addtional parameters as needed to fill in
the blanks.
In practice, none of the code ever uses the printf-style formatting.
We always pass exactly two parameters. We burn CPU cycles scanning
the string for format specifiers and never find any.
I eliminated the unused variable parameters and turned osrfHashGet()
into a simple two-parameter function. Just in case anybody ever
wants it, I also cloned the original version into a new function
named osrfHashGetFmt, which accepts a variable number of arguments
as before.
Note that, since the signature of the function is changing,
it is necessary to recompile any open-ils programs that
call it, namely:
Add two new commands, "open" and "close", to open and close ongoing
connections to specified services. (Otherwise a connection is created
and destroyed for every request.)
Main purpose: to be able to use srfsh for database operations that require
transactions.
Warning: typically the <keepalive> value will need to be increased for
the service in question in opensrf.xml, or else the server will close
the connection before you can type your request.

from an osrfList without destroying it, and returns a pointer to
the item thus removed.
2. Create a new jsonObjectExtractIndex, which removes a

jsonObjectRemoveIndex(). Contrary to the original comment, this

In osrf_system_shutdown(): provide a return value for an early
return (since the function is of type int).
It's not clear whether these are the right semantics, since we
never capture the return value anyway. But if we're going
to return anything at all, it makes sense to return something
different in the case of an early return.

not sure why this is an issue now (different perl/json:xs verions?), but
$obj->{$k} = JSONObject2Perl($bool)
results in 'Modification of a read-only value attempted', while
$obj->{$k} = $bool

just missing something?

This update mainly tightens the error handling.
1. If there aren't enough arguments on the command line, return EXIT_FAILURE
instead of zero.
2. Defer the call to set_proc_title() until we are done using the command
line arguments, so that we don't have to make copies of them.
3. Check the return value from osrfConfigInit(). Otherwise a NULL (caused,
e.g., by a missing config file) leads to a segfault.
4. If the config file doesn't define any routers to spawn, exit immediately
with an error message before entering the fork loop.
5. If a child process returns (due to an error) instead of entering the
normal endless loop, break out of the fork loop. Otherwise the child
remains in the fork loop and spawns children of its own (unless it's the
last child to be spawned). At best, that's just silly.
6. Append an newline to a message issued from setupRouter(). (It's not
clear why this message goes directly to stderr instead of to the usual
logging machinery, which at this point is directed to stderr anyway.)
