2020-12-15classify: add pcap/trace classfier mgmt API callsJon Loeliger4-188/+709
Add lookup/get/set API calls to manage both PCAP and Trace filtering Classifier tables. The "lookup" call may be used to identify a Classifier table within a chain of tables taht matches a particular mask vector. For efficiency, this call should be used to determine to which table a match vector should be added. The "get" calls return the first table within a chain (either a PCAP or the Trace) set of tables. The "set" call may be used to add a new table to one such chain. If the "sort_masks" flag is set, the tables within the chain are ordered such that the most-specific mask is first, and the least-specific mask is last. A call that "sets" a chain to ~0 will delete and free all the tables with a chain. The PCAP filters are per-interface, with "local0", (that is, sw_if_index == 0) holding the system-wide PCAP filter. The Classifier used a reference-counted "set" for each PCAP or trace filter that it stored. The ref counts were not used, and the vector of tables was only used temporarily to establish a sorted order for tables based on masks. None of that complexity was actually warranted, and where it was used, the same could be achieved more simply.

2020-11-10classify: fix classify filter trace del cli processingJon Loeliger1-35/+49
When a 'del' is used to delete a classify table, only the mask is needed to locate the table. Any match vector is unneeded. The tests failed to notice this, but if the test is run by hand in vppctl, it issues a parse error. Fix the test so that it doesn't supply irrelevant data. Fix the CLI processing to read always complete newline terminated line of input instead. This allows unneeded CLI parameters to be ignored. It also necessitated fixing a trace test which had then erroneously split a single CLI command over multiple lines. While in the area, fix a latent bug on table matching where a test for compatible mask vector sizes were not matching impedance properly (byte vs ux32x4).
