Refactor prof_dump() to reduce contention. Refactor prof_dump() to use a two pass algorithm, and prof_leave() prior to the second pass. This avoids write(2) system calls while holding critical prof resources. Fix prof_dump() to close the dump file descriptor for all relevant error paths. Minimize the size of prof-related static buffers when prof is disabled. This saves roughly 65 KiB of application memory for non-prof builds. Refactor prof_ctx_init() out of prof_lookup_global().
