2021-01-28qapi: Use QAPI_LIST_APPEND in trivial casesEric Blake20-222/+96
The easiest spots to use QAPI_LIST_APPEND are where we already have an obvious pointer to the tail of a list. While at it, consistently use the variable name 'tail' for that purpose.

2021-01-28qapi: Introduce QAPI_LIST_APPENDEric Blake1-0/+13
Similar to the existing QAPI_LIST_PREPEND, but designed for use where we want to preserve insertion order. Callers will be added in upcoming patches. Note the difference in signature: PREPEND takes List*, APPEND takes List**.

2021-01-28qapi: A couple more QAPI_LIST_PREPEND() stragglersEric Blake2-27/+16
Commit 54aa3de72e switched multiple sites to use QAPI_LIST_PREPEND instead of open-coding, but missed a couple of spots.

2021-01-28net: Clarify early exit conditionEric Blake1-0/+2
On first glance, the loop in qmp_query_rx_filter() has early return paths that could leak any allocation of filter_list from a previous iteration. But on closer inspection, it is obvious that all of the early exits are guarded by has_name, and that the bulk of the loop body can be executed at most once if the user is filtering by name, thus, any early exit coincides with an empty list. Add asserts to make this obvious.
