Subject: 27.0.60; [PATCH] Unify and improve gdb-mi source window display

From: Yuan Fu <[email-masked]>
Date: Sat, 28 Mar 2020 00:03:21 -0400

Before this change, stepping and other gdb command handlers use 'gud-display-line’ and 'gdb-goto-breakpoint' uses 'gdb-display-source-buffer'.  Now whenever gdb-mi code tries to open a source buffer, 'gdb-display-source-buffer’ is used.  Also, we simplify the logic in 'gdb-display-source-buffer’ and add a feature to limit the maximum number of source windows.

From a user’s perspective, this change solves two problems: 1. The behavior difference between jumping to break point and stepping (and other command) 2. Gdb-mi opening more windows than I wanted for displaying source files.
