Wim Taymans 4de0f83aca security: add missing NULL checks after realloc/strdup in LV2 plugin
Memory Safety: Medium

Two issues in the LV2 filter-graph plugin:

1. uri_table_map(): realloc() result was assigned directly to
   table->data, losing the original pointer on failure (memory leak)
   and causing a NULL pointer dereference on the next access. Also
   the subsequent strdup() had no NULL check. Fixed by using a
   temporary pointer for realloc and checking strdup's return.

2. lv2_state_retrieve(): realloc() of sd->tmp was used without a
   NULL check, so a failed allocation would cause sd->tmp to become
   NULL and be immediately passed to spa_json_parse_stringn(). Fixed
   by checking the realloc result before assignment.
