[jdk17u-dev] RFR: 8292989: Avoid dynamic memory in AsyncLogWriter [v2]

[Xin Liu]

> This patch is *NOT* a clean backport.  The logic part is exactly the same, but I have to adjust code in the following parts:
> 1. change from KVHashtable to ResourceHashtable because we want to use resourceArea instead of C_HEAP. 
> 2. we added lambda-API iterator() to ResourceHashtable. Instead of backporting all patches from TIP, we just reuse the original iterator(). 
> 
> 
> template<typename Function>
> void iterate(Function function) const { // lambda enabled API
> 
> 
> Testing: 
> jdk-test1 tests including gtest. 
> Manually check there's no malloc/free in runtime.

Xin Liu has updated the pull request incrementally with one additional commit since the last revision:

  Revert resourceHash.hpp and use functor instead of C++ lambda.
