apr_json: object keys are strings.
2b510a8 
Make this clear in the API by requiring a usual string in apr_json_object_set()
and creating the apr_json_string_t from it.

It's also more user friendly as otherwise apr_json_string_create() is to be
used when setting an entry.

Also, axe the 'pool' arg from apr_json_array_add() since it's not needed.

Merge r1883750 from trunk:
2b85c17 
apr_pools: lock parent pool in pool_destroy_debug().

By using apr_pool_clear_debug() instead of pool_clear_debug() in
pool_destroy_debug() we gain the locking provided by the former and thus
protection from concurrent access from apr_pool_walk_tree(), which is
undefined behaviour.

While pool_destroy_debug()=>apr_pool_clear_debug()=>pool_clear_debug() calls
pool_destroy_debug() for all the children pools, this does not cause a deadlock
because apr_pool_clear_debug() locks the parent pool only (not the pool itself)
and thus pool_destroy_debug(pool->child) locks the current pool with no issue.

This fixes use-after-free like the below in httpd (with -D APR_POOL_DEBUG):

apr_pools: lock parent pool in pool_destroy_debug().
94d2e04 
By using apr_pool_clear_debug() instead of pool_clear_debug() in
pool_destroy_debug() we gain the locking provided by the former and thus
protection from concurrent access from apr_pool_walk_tree(), which is
undefined behaviour.

While pool_destroy_debug()=>apr_pool_clear_debug()=>pool_clear_debug() calls
pool_destroy_debug() for all the children pools, this does not cause a deadlock
because apr_pool_clear_debug() locks the parent pool only (not the pool itself)
and thus pool_destroy_debug(pool->child) locks the current pool with no issue.

This fixes use-after-free like the below in httpd (with -D APR_POOL_DEBUG):
