The `absolute` and `relative` locktimes as well as the `Sequence` are
all primitive bitcoin types.
Move the `Sequence`, and `locktime` stuff over to `primitives`.
There is nothing surprising here, the consensus encoding stuff stays in
`bitcoin` and we re-export everything from `blockdata`.
Eventually we would like all our crates other than `bitcoin` to be able
to be used without an allocator. Currently, and during crate smashing,
this is not that useful because so much of the code comes from `bitcoin`
and relies on the availability of an allocator.
As an initial step, add the `alloc` feature to `addresses` , `base58`,
and `primitives`.
In order to to keep `--no-default-features` builds working make the
crates empty if the `alloc` feature is not enabled. This is a suboptimal
solution because the error messages users will get when they forget to
enable `alloc` will be confusing (eg something like primitives does not
contain Transaction). However our CI script (`run_task.sh`) expects
`--no-default-features` to build cleanly (as do I).
Move the `opcodes` module to the new `primitives` crate. This is pretty
straight forward, some things to note:
- Are we ok with the public wildcard re-export from `blockdata`? I think
so because the whole `blockdata` module should, IMO, be deleted after
everything in it is moved to `primitives`.
- `decode_pushnum` becomes public.
Includes addition of a `patch` section for `primitives` in the
`bitcoin/embedded` crate.
Introduce an empty `bitcoin-primitives` crate.
We were give the name on crates.io and previously a version
`v0.1.16-alpha` was released so we use `v0.100.0`.
