solana-feature-set 2.1.2

Solana runtime features.
Documentation
Collection of all runtime features. Steps to add a new feature are outlined below. Note that these steps only cover the process of getting a feature into the core Solana code. - For features that are unambiguously good (ie bug fixes), these steps are sufficient. - For features that should go up for community vote (ie fee structure changes), more information on the additional steps to follow can be found at: 1. Generate a new keypair with `solana-keygen new --outfile feature.json --no-passphrase` - Keypairs should be held by core contributors only. If you're a non-core contributor going through these steps, the PR process will facilitate a keypair holder being picked. That person will generate the keypair, provide pubkey for PR, and ultimately enable the feature. 2. Add a public module for the feature, specifying keypair pubkey as the id with `solana_pubkey::declare_id!()` within the module. Additionally, add an entry to `FEATURE_NAMES` map. 3. Add desired logic to check for and switch on feature availability. For more information on how features are picked up, see comments for `Feature`.
