e16b6a7188 rpc: Rename size to vsize in mempool related calls (Miguel Herranz)
Pull request description:
#13008 rebased on `master`, with release notes split out.
> In getmempoolancestors, getmempooldescendants, getmempoolentry and getrawmempool RPCs size returns the virtual transaction size as defined in BIP 141. Renaming it to vsize makes it consistent with returned value and other calls such as getrawtransaction.
>
> Related to #11218.
