chore: fix clippy warnings on latest nightly rust ( #78 )
...
btw `#[cfg(...)]` was used implicitly and expanded always lead to `use
alloc::collections::BTreeMap as Map;`
the second `cfg(std)` just doesn't work bcz `featureS`

I tried locally merge `fix-tests` and `fix-clippy` branches and CI
should work after my PRs

<h2>v0.21.0 - 2023-01-04</h2>
<h3>Added</h3>
<ul>
<li>Add support for resumable function calls. (<a
href="https://github-redirect.dependabot.com/paritytech/wasmi/pull/598 ">paritytech/wasmi#598</a>)
<ul>
<li>This feature allows to resume a function call upon encountering a
host trap.</li>
</ul>
</li>
<li>Add support for concurrently running function executions using a
single <code>wasmi</code> engine.
<ul>
<li>This feature also allows to call Wasm functions from host functions.
(<a
href="https://github-redirect.dependabot.com/paritytech/wasmi/pull/590 ">paritytech/wasmi#590</a>)</li>
</ul>
</li>
<li>Add initial naive WASI support for <code>wasmi</code> using the new
<code>wasmi_wasi</code> crate. (<a
href="https://github-redirect.dependabot.com/paritytech/wasmi/pull/557 ">paritytech/wasmi#557</a>)
<ul>
<li>Special thanks to <a href="https://github.com/OLUWAMUYIWA ">Onigbinde
Oluwamuyiwa Elijah</a> for carrying the WASI support efforts!</li>

<li><strong>Note:</strong> There is ongoing work to integrate WASI
support in <code>wasmi_cli</code> so that the <code>wasmi</code> CLI
will then
be able to execute arbitrary <code>wasm-wasi</code> files out of the box
in the future.</li>
</ul>
</li>
<li>Add <code>Module::imports</code> that allows to query Wasm module
imports. (<a

<a
href="https://github-redirect.dependabot.com/paritytech/wasmi/pull/583 ">paritytech/wasmi#583</a>)</li>
</ul>
<h3>Fixed</h3>
<ul>
<li>Fix a bug that imported linear memories and tables were initialized
twice upon instantiation. (<a
href="https://github-redirect.dependabot.com/paritytech/wasmi/pull/593 ">paritytech/wasmi#593</a>)</li>
<li>The <code>wasmi</code> CLI now properly hints for file path
arguments. (<a
href="https://github-redirect.dependabot.com/paritytech/wasmi/pull/596 ">paritytech/wasmi#596</a>)</li>
</ul>
<h3>Changed</h3>
<ul>
<li>The <code>wasmi::Trap</code> type is now more similar to Wasmtime's
<code>Trap</code> type. (<a
href="https://github-redirect.dependabot.com/paritytech/wasmi/pull/559 ">paritytech/wasmi#559</a>)</li>
<li>The <code>wasmi::Store</code> type is now <code>Send</code> and
<code>Sync</code> as intended. (<a
href="https://github-redirect.dependabot.com/paritytech/wasmi/pull/566 ">paritytech/wasmi#566</a>)</li>
<li>The <code>wasmi</code> CLI now prints exported functions names if
the function name CLI argument is missing. (<a
href="https://github-redirect.dependabot.com/paritytech/wasmi/pull/579 ">paritytech/wasmi#579</a>)</li>
<li>Improve feedback when running a Wasm module without exported

* save: optimized gas func a bit (benches work, fixture tests fail)
* 1033% overhead on many_blocks.wasm when mut_global gas_metering together with stack_height
* size overhead test for both gas metering methods + stack limiter
* added more benches
* improved print_size_overhead test
* test for comparing size overheads of two gas_metering injectors
* before optimization: benches + size overhead
* optimization try-1: inline part of gas func instructions: +benches +size overheads
* optimization try-2: inline hot path of gas fn: +benches +size overheads
* opt try-3: count for gas fn cost on the caller side: +benches +size overhead
* revert to initial version but with static gas fn cost on the caller side: +benches +sizes
* tests fixed
* use newest wasmi 0.20: +benches +docs updated
* use if-else block instead of Return: +benches

Fix counting of the local variables
...
The code assumed that the number of `Local` and number of locals is the
same thing. In reality though it is not. `Local` actually represents a
group of locals with the same type. The group can declare more than one
variable and the number of them is returned by `Local::count`.
In this PR we acknowledge this fact. Along the way we add a checked
arithmetic for locals_count and max_stack_height summation.

Don't generate duplicate thunks
...
Previously, functions that appear in multiple places
(exported, start function, table) would generate a thunk
for each place they appear in. Those additional thunks are
identical and only only one of them would be referenced.
Main offender are tables with redundant entries.
This commit eliminates those duplicate thunks without adding
any additional overhead.

Fix Instruction::CallIndirect stack height metering

The stack height metering for functions containing
CallIndirect was wrong. The code did not take into
consideration that is pops one value from the stack.
The effect was that the stack height of functions

Preserve "deploy" when optimizing pwasm ctor module
...
When optimizing the constructor module for a PWasm contract the "deploy" symbol is preserved instead of the "call"
symbol. Before this change `build` would error for PWasm contracts because `pack_instance` would not find the "deploy"
symbol in the optimized contract.
Fixes #128
