gdb: New maint info line-table command.
Add a new command 'maint info line-table' to display the contents of GDB's internal line table structure. Useful when trying to understand problems (within gdb) relating to line tables. gdb/ChangeLog: * symmisc.c (maintenance_info_line_tables): New function. (maintenance_print_one_line_table): New function. (_initialize_symmisc): Register 'maint info line-table' command. * NEWS: Mention new command. gdb/doc/ChangeLog: * gdb.texinfo (Symbols): Document new 'maint info line-table' command. gdb/testsuite/ChangeLog: * gdb.base/maint.exp: New tests for 'maint info line-table'.
