* split `decls.nim` into smaller modules - allows using parts of the ABI without compiling all of `bearssl` * deprecate functions with `Br` prefix - there are duplicate exports both with and without `Br` for the same function and we use both in consumers like `chronos` and `libp2p` * fix several cases of incorrectly mapped types * use `var` for certain arguments that can't be `nil` * add script to regenerate ABI with `c2nim` * consistently use `uint` for length (`int` was sometimes used) The Split likely needs more cleanup work - this is a first cut to get the idea in place. In the new layout, `bearssl/abi/` contains "raw" nim mappings while hand-written helpers are in `bearssl/`.

# For each bearssl header file, we create one nim module that compilers the

|
|
# modules make sure to import these dependencies so that the correct C source
|
|
# files get compiled transitively.

# Most of the header-like content was generated with c2nim, then hand-edited.

#
|
|
# For historical reasons, some functions and types are exposed with a "Br"
|
|
# prefix - these have been marked deprecated.

# Some functions take a length as input - in bearssl, `csize_t` is used for this
|
|
# purpose - wrappers do the same
