NEWS:
* Switching endianness mid-byte no longer potentially re-reads bytes.
* bit_offset now consistently refers to the number of bits already
  read.
* HParsedTokens now have a bit_length field; this is a size_t.  This
  may be removed for memory reasons.

The bit writer has not yet been updated to match; the result of
switching bit writer endianness in the middle of a byte remains
undefined.

llvm doesn't care about your size

Fix compilation when PKG_CONFIG_PATH is not in environ

Remove vacuous states in base64_sem?.c

Move backend names into src/benchmark.c

They apparently removed alloc_size at some point (it was a no-op
beforehand), causing the attribute to throw an error when clang compiles
anything including allocator.h.

I don't think these actually affect correctness since there's no way for
0x40 or 0x60 to show up in a parse tree anyway, but they're confusing.

It's causing unreferenced-variable warnings, and isn't referenced
anywhere aside from benchmark.c. If client code is likely to reference
it, perhaps move it into another header, so people who include hammer.h
don't have to refer to it to have warning-free code.

Scons now doesn't throw away PKG_CONFIG_PATH, so NixOS can build it

Scons now doesn't throw away /home/stewart/.nix-profile/lib/pkgconfig:/nix/var/nix/profiles/default/lib/pkgconfig:/run/current-system/sw/lib/pkgconfig, so NixOS can build it

add h_permutation

h_put_value and h_get_value done.

change pointer type to uintptr_t for portability

implement h_with_endianness combinator

Added NetBSD and OpenBSD ports

Make HHashTable resizeable and improve benchmarking output

Ported to OpenBSD.

Make build work on NetBSD

NetBSD's character class test macros are defined such that they produce
a compiler warning when given a char argument. Adding a cast to the call
fixes this.
