* solana-program - altbn128: add g1 & g2 compression
still fixing tests for point of infinity
feat: proof compression syscall working
add rust test to ci
remove prints
added c test
added sycall pricing
* fixed ci checks
* refactored altbn128 and compression
Computing Poseidon[0] hashes is too expensive to be done in a Solana
program in one transaction. Poseidon is a zero-knowlege proof friendly
hash function, used by the majority of ZK-based projects, including the
ones built on top of Solana.
This change introduces the `sol_poseidon` syscall which takes 2D byte
slice as an input and then calculates a Poseidon hash using a BN254
curve and the following Poseidon parameters:
* x^5 S-boxes
* width - 2 ≤ t ≤ 13
* inputs - 1 ≤ n ≤ 12
* 8 full rounds and partial rounds depending on t: [56, 57, 56, 60, 60,
63, 64, 63, 60, 66, 60, 65]
Computation of Poseidon hashes is done with the light-poseidon[1]
crate, which is audited[2] and compatible with Circom[3] (BN254 curve,
the same parameters and constants).
Proposed compute costs depend on number of inputs and are based on
light-poseidon benchmarks[4].

* Fix C headers (the name of the syscall was incorrect).
* Add C SBF tests using the alt_bn128 syscall.
* Fix the Rust SBF program:
* Do not use serde and array-bytes, provide test cases as byte arrays
directly.
* Use the `custom_heap_default` macro.
* Replace `bpf` with `sbf` in the crate name.
* Execute both previously existing Rust tests and new C tests in
`programs/sbf/tests`, so they are actually tested on CI.
* Bump sbf-tools to v1.32
This version of sbf-tools is based on Rust 1.65.0 and LLVM 15.0.
* Temporary ignore build-sbf tests until issue with buildkite cache resolved
