/**
 * @file allocator.c
 * @brief The process-wide allocator table used for all of infix's internal heap allocations.
 *
 * Every internal allocation is routed through `infix_allocator` (see the `infix_*`
 * memory macros in `infix.h`). By default the table points at the C library's
 * `malloc`/`calloc`/`realloc`/`free`, so out of the box infix behaves exactly as it
 * always has. Host applications can install their own allocator with
 * `infix_set_allocator()` (e.g. a language runtime's tracked heap) so that every
 * block infix allocates and returns to the host comes from a single, known allocator.
