69e1ec0331 Get rid of secp256k1_fe_const_b (Pieter Wuille)
Pull request description:
Replaces #1282.
Its only remaining use is in a test introduced in #1118, and it is easily replaced by the new `secp256k1_fe_add_int` from #1217.

To use, invoke `cmake` with argument `--preset dev-mode`.
Solves one item in #1235.
One disadvantage over `./configure --enable-dev-mode` is that CMake
does not provide a way to "hide" presets from users. That is,
`cmake --list-presets` will list dev-mode, and it will also appear
in `cmake-gui`, even though it's not selectable there due to bug
https://gitlab.kitware.com/cmake/cmake/-/issues/23341. (So in our
case, that's probably rather a feature than a bug.)
We curently use version 3 presets which require CMake 3.21+.
Unfortunately, CMake versions before 3.19 may ignore the `--preset`
argument silently. So if the preset is not picked up, make sure you
have a recent enough CMake version.
More unfortunately, we can't even spell this warning out in
CMakePresets.json because CMake does not support officially support
comments in JSON, see
- https://gitlab.kitware.com/cmake/cmake/-/issues/21858
- https://gitlab.kitware.com/cmake/cmake/-/merge_requests/5853 .
We could use a hack hinted at in
https://gitlab.kitware.com/cmake/cmake/-/issues/21858#note_908543
but that's risky, because it could simply break for future versions,
and we probably want to use presets not only for dev mode.

Pull request description:
From [IRC](https://gnusha.org/secp256k1/2023-01-31.log):
> 06:29 \< hebasto\> What are reasons to define the `SECP256K1_INLINE` macro in user's `include/secp256k1.h` header, while it is used internally only?
> 06:32 \< hebasto\> I mean, any other (or a new dedicated) header in `src` looks more appropriate, no?
> 06:35 \< sipa\> I think it may just predate any "utility" internal headers.
> 06:42 \< sipa\> I think it makes sense to move it to util.h
Pros:
- it is a step in direction to better organized headers (in context of #924, #1039)
Cons:
- code duplication for `SECP256K1_GNUC_PREREQ` macro

ef49a11d29 build: allow static or shared but not both (Cory Fields)

Pull request description:
Continuing from here: https://github.com/bitcoin-core/secp256k1/issues/1224#issuecomment-1460438227
Unfortunately it wasn't really possible to keep a clean diff here because of the nature of the change. I suggest reviewing the lib creation stuff in its entirety, sorry about that :\
Rather than allowing for shared and static libs to be built at the same time like autotools, this PR switches to the CMake convention of allowing only 1.
A new `BUILD_SHARED_LIBS` option is added to match CMake convention, as well as a `SECP256K1_DISABLE_SHARED` option which overrides it. That way even projects which have `BUILD_SHARED_LIBS=1` can opt-into a static libsecp in particular.
Details:
Two object libraries are created: `secp256k1_asm` and `secp256k1_precomputed_objs`. Some tests/benchmarks use the object libraries directly, some link against the real lib: `secp256k1`.
Because the objs don't know what they're going to be linked into, they need to be told how to deal with PIC.
The `DEFINE_SYMBOL` property sets the `DLL_EXPORT` define as necessary (when building a shared lib)

There is little reason for having the number of bits in the scalar as a parameter, as I don't think there are any (current) use cases for non-256-bit scalars.
