Bug Fixes:

Under the Hood:
- Debian compatibility level changed from 4 to 5.
- Make sure we can deal with older pkg-config, which needs leading arguments.
- Use "embedded" symbols for xmalloc(), xfree() and friends.
- Added "query_trace" property to trace all queries which were searched.
- Moved halloc-based string functions like h_strdup() to dedicated hstrfn.c.
- Expanded search mask to 64 bits to be able to hold all digits and letters.
- Count aliased queries and hits from aliases.
- Pre-compute shared file media type at record creation time.
- Pass query limits to st_search() to avoid needless pattern matching.
- Added h_strsplit() and h_strsplit_set().
- Added strvec_append_with() to expand vector by appending another vector.
- crash_assert_logv(): don't call crash_mode() if assert failure was recorded.
- entropy_clock_time(): mix the entropy nonce through hashing for more diffusion.
- node_can_accept_connection(): only send headers back when handshaking.
- qrp_add_file(): optimized to avoid computing word length if not required.
- thread_stack_check_overflow(): ignore virtual addresses outside stack range.
- vmm_init_once(): ensure any shared library for stacktrace unwinding is loaded.
