BPF syscall symbols are confusing

[jackcmay]

Problem

BPF syscall symbols service both Rust and C and different symbols are exported for each language which is not necessary and confusing

Proposed Solution

Consolidate the exported syscall symbols to a single exported symbol where possible.

For example, instead of exporting sol_log and sol_log_ just export `sol_log_' and point all languages to it.

This is a breaking change for existing programs that require all pre-compiled programs to be rebuilt and should go into the first public release that supports programs.

ok if we're going to do this it needs to go into v1.1, and pretty quickly!

[jackcmay]

Yup, how quickly?

Next week or so doable? Ideally we have some soak time on testnet before promoting to mainnet-beta at the end of May

Sounds good, I can get it in asap
