#### Problem
The existing StoredAccountMeta requires the file and in-memory layout of
account metadata to match StoredMeta and AccountMeta. This limits the
flexibility to implement different accounts storage file formats.
#### Summary of Changes
This PR abstracts out StoredAccountMeta as an Enum.
1. replace hardcoded loaded accounts data size limit with compute budget instruction;
2. new transaction error for invalid account data size limit
3. test requested limit with combination of features and transactions
As `Range` is a special case of an `Iterator`, this is a generalization
that makes `get_all_accounts()` accept other kinds of ranges. Such as
`RangeInclusive`.
#### Problem
The existing append_accounts returns a vector of offsets, which accounts-db
later uses it to infer the storage size of each account. However, such inference
does not apply to the new hot/cold storage format.
#### Summary of Changes
This PR changes the return value of append_accounts() to `Vec<StoredAccountInfo>`,
which includes both offset and storage size information of an account.
* support loading snapshots with > 1 append vec per slot
* pr feedback
* drain to into_values
* unwrap() -> expect()
* loop to find non-conflicting file and add test
All the references returned from a `StoredAccountMeta` instance
actually come from the underlying account. As written, the lifetimes of
the returned references are constrained by the lifetime of the
`StoredAccountMeta` instance.
While technically correct, it is overly strict. It is totally fine to
use the returned reference as long as the underlying account is alive.
Which could be longer than the lifetime of the `StoredAccountMeta`
wrapper.
This PR makes all the StoredAccountMeta fields pub(crate)
and provides getter functions to access its member fields.
This PR is a preparation step for abstracting out StoredAccountMeta.
* introduce workspace.package
* introduce workspace.dependencies
* read version from root cargo.toml
* pass check when version = { workspace = true }
* don't bump version when version = { workspace = true }
* including workspace Cargo.toml when bump version
* programs/sbf use workspace inheritance
* fix increasing cargo version ignore program/sbf/Cargo.toml
#### Problem
As we start supporting new storage formats, those account-meta
structs will be shared by different storage formats and thus need
a new home.
#### Summary of Changes
This PR creates meta.rs under account_storage and moves all the account-meta
structs out from append_vec.rs.
