/* 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. */
