[PATCH 00/10] perf parse-events: enable more flex/bison warnings

[Ian Rogers <irogers@google.com>]

All C compiler warnings are disabled are disabled by -w. This change
removes the -w from flex and bison targets. To avoid implicit
declarations header files are declared as targets and included.

Tested with GCC 9.3.0 and clang 9.0.1.

Previously posted as a single change:
