Added code and assertions to make sure tokenizer_t arrays are properly sorted.
VXML parser: use G_STRFUNC instead of hardwiring the routine name in messages.
aje_key_init(): make sure the global AJE context is also initialized.
Added aje_thread_random_bytes() to generate randomness from the thread's pool.
Added "stronger" (but much slower) AJE random number generation routines.

Instead of relying on a pre-computed buffer of random numbers, these routines
request the needed amount of random values from the AJE pool, involving a
rekeying of the context (and possibly a re-seeding), which makes them slower
to generate because the overhead is paid each time.
Make sure we extract GTA_VERSION and skip GTA_VERSION_NUMBER lines.
Regenerated Configure to fix endianess detection of IEEE-754 floats on Solaris.
