* alloc: Don't require size % align == 0Tavian Barnes2024-11-021-8/+0
| | | | | | | | | Allowing unaligned sizes will allow us to allocate aligned slabs with additional metadata in the tail without ballooning the allocation size for large alignments.

* xtime: Add a wrapper for timer_create()/setitimer()Tavian Barnes2024-10-101-0/+9
| | | | | | setitimer() is obsolescent in POSIX 2008 and removed from POSIX 2024. However, at least macOS doesn't implement the new timer_create() API, so we still need the setitimer() fallback.

* build: Replace `make config` with a `./configure` scriptTavian Barnes2024-04-2933-0/+327
This lets us do more traditional out-of-tree builds like $ ../path/to/bfs/configure $ make The .mk files are moved from ./config to ./build, mostly so that ./configure will auto-complete easily.
