Stop storing the canonical list of arguments separately. For the canonicalize-flags command, we want to avoid showing options that either have no values in their own right (such as expansion options and wrapper options) and instances of options that did not make it to the final value. This is work we already do in OptionValueDescription, so we can generate the canonical form from the values tracked there, instead of tracking it separately.
This means the canonical list is more correct where implicit requirements are concerned: implicit requirements are not listed in the canonical form, but now the values they overwrote will be correctly absent as well.
Use this improved list for the effective command line published to the BEP.
RELNOTES: Published command lines should have improved lists of effective options.

An option has precedence over previous options at the same enum-valued priority. Track its placement in this ordering explicitly.
This will allow after-the-fact expansion of expansion options such that they correctly take precedence or not compared to other mentions of the same flag. This is needed to fix --config's expansion.

For tools that wrap Bazel in some way, the original way that the tool was invoked can be a useful piece of information to track when logging what Bazel did and why.
In order to output this information in the same way that Bazel outputs its command lines, we accept --tool_command_line in the structure command line format that Bazel uses in the BEP. These structured command lines are protos that we expect as a base64 encoded byte array. For simple scripts that wish to use this feature without compiling the proto, we will also accept any old string (that cannot be interpreted as a base64 encoding) as a single "chunk" in a structured command line.
This is experimental for now and users should not get attached to the format. We will remove the experimental_ prefix when it is stable.
RELNOTES: None.

Change ceb1013c1ca0238188e2714442fcfb2efb16bc6a added an event for
the structured command line to the BEP. Announce that event as a
child of the build-starting event so that it gets properly chained
and does not have to be chained in by a progress event.

This is part of the effort outlined in https://bazel.build/designs/2017/07/13/improved-command-line-reporting.html. The refactoring of the options parser is not yet complete, so we still do not have complete & correct information about the canonical command line. Where the information is blatantly incorrect, a best approximation was made, with comments and tests documenting the deficiencies.
Change the names of the initial CommandLine fields in the BEP to be explicitly identified as unstructured.
RELNOTES: None.
