[4/5] git commit: TS-1006: Make InkFreeList memory pool configurable
TS-1006: Make InkFreeList memory pool configurable
Introduce four configurable parameters in records.config file, which will
be used to control debug information and adjust the behavior of reclaimable
InkFreeList memory pool:
* proxy.config.allocator.debug_filter
Dump debug information according bit mask of debug_filter, if a bit is set
in the mask, then debug information of the corresponding action are dumped:
bit 0: reclaim memory in ink_freelist_new
bit 1: allocate memory from partial-free Chunks(if exist) or OS
* proxy.config.allocator.enable_reclaim
The value of enable_reclaim should be 0 or 1. Default 0, reclaim disabled.
* proxy.config.allocator.reclaim_factor
The value of reclaim_factor should be in 0.0 ~ 1.0, allocator use it to
calculate average value of idle memory in InkFreeList, which will determine
when to reclaim memory. The larger the value, the faster the reclaiming.
This flag is effective only when enable_reclaim is set.
* proxy.config.allocator.max_overage
Allocator will reclaim memory only when it continuously satisfy the reclaim
condition for max_overage times. This flag is effective only when
enable_reclaim is set.
