+/* Find and optionally add an entry in the change_sections list.
+
+ We need to be careful in how we match section names because of the support
+ for wildcard characters. For example suppose that the user has invoked
+ objcopy like this:
+
+ --set-section-flags .debug_*=debug
+ --set-section-flags .debug_str=readonly,debug
+ --change-section-address .debug_*ranges=0x1000
+
+ With the idea that all debug sections will receive the DEBUG flag, the
+ .debug_str section will also receive the READONLY flag and the
+ .debug_ranges and .debug_aranges sections will have their address set to
+ 0x1000. (This may not make much sense, but it is just an example).
+
+ When adding the section name patterns to the section list we need to make
+ sure that previous entries do not match with the new entry, unless the
+ match is exact. (In which case we assume that the user is overriding
+ the previous entry with the new context).
+
+ When matching real section names to the section list we make use of the
+ wildcard characters, but we must do so in context. Eg if we are setting
+ section addresses then we match for .debug_ranges but not for .debug_info.
+
+ Finally, if ADD is false and we do find a match, we mark the section list
+ entry as used. */
