misbehaved because we did not notice this needs to grab lines
that have the given two fixed strings at the same time.

This further updates the built-in grep engine so that we can say
something like "this pattern should match only in head". This
can be used to simplify grepping in the log messages.

This makes three functions and associated option structures from
builtin-grep available from other parts of the system.
* options to drive built-in grep engine is stored in struct
grep_opt;
* pattern strings and extended grep expressions are added to
struct grep_opt with append_grep_pattern();
* when finished calling append_grep_pattern(), call
compile_grep_patterns() to prepare for execution;
* call grep_buffer() to find matches in the in-core buffer.
This also adds an internal option "status_only" to grep_opt,
which suppresses any output from grep_buffer(). Callers of the
function as library can use it to check if there is a match
without producing any output.
