* tuiDisassem.c (tui_disassemble): New function to disassemble
several lines in a buffer. (tui_find_disassembly_address): New function to search backward or forward a disassembly line. (tuiSetDisassemContent): Use tui_disassemble to obtain the real content and format it in the window. (tuiShowDisassemAndUpdateSource): Remove unused locals. (tuiVerticalDisassemScroll): Use tui_find_disassembly_address to obtain the address to disassemble for the scrolling. * tuiDisassem.h (tuiGetBeginAsmAddress): Update. * tuiSourceWin.c (tuiUpdateSourceWindowAsIs): Don't pass symtab.
